Where to start when Adjusting and Balancing Must
There are two main steps to Adjusting and Balancing Must, which consist of adjusting your Brix and adjusting your pH/TA. We’ll cover what they are, what they mean, and how to do both.
Where to start when Adjusting and Balancing Must
Firstly, you’ll need your starting numbers. You’ll have to measure your Brix, pH, and TA. To measure your Brix, you can use a Triple Scale Hydrometer. To measure your pH and TA, you’ll need a titration setup or an acid test kit, and some mathematical skills. If I lost you at math skills, don’t fret – Musto Wine Grape Company offers a wide variety of testing including pH and TA testing!
What are Brix, pH, and TA?
Brix is a measurement of the sugar content within your must. This indicates the degree of the grapes’ ripeness at harvest. The higher the Brix, the higher the alcohol content in the finished wine. To get an alcohol conversion level, simply multiply your Brix by .55. pH is the measurement of the ripeness in relation to acidity. A low pH wine is crisp and tart, while higher pH wines are more prone to bacteria growth and spoilage (3.9 pH and higher). Wine generally falls between 3 or 4 on the pH scale, with 3 – 3.4 being the average for white wines and about 3.3 – 3.6 for reds. Finally, TA is measuring acidity by volume. TA stands for Total Acidity. Usually, the higher the pH the lower the TA and vise-versa. This is not always the case though, and you may need to make adjustments to your must. Hold tight, how to do that is next!
How to Adjust and Balance Must
If you need to lower your TA, we recommend using Potassium Bicarbonate. Adding Potassium Bicarbonate to your must will reduce acidity. Make sure to add slowly, as it foams significantly. It is also recommended to add to water first, then add the mixture to your must. Under typical conditions and normal use, Potassium Bicarbonate neutralizes Tartaric Acid. It’s best used when the TA is high and pH is low, due to the fact it causes an increase in pH. It also adds potassium to the must and that requires cold stabilization. Potassium Bicarbonate can contribute to tartrate instability in wine, which is also why cold stabilization is recommended. It is also good to note that the addition of Potassium Bicarbonate will cause a reaction in the wine which will vary from wine to wine and the pH will not shift in a predictable manner. Bench trials should always be done first when attempting to adjust pH.
To lower pH, the most effective method is to add Tartaric Acid. If both TA and pH are too high, tackle the pH. The pH is more critical to the wine chemistry. This addition also requires bench testing to find the best addition.
To raise the brix, we can add table sugar to the must, be sure to dilute the sugar first with hot spring water before adding it to the must or juice. There are good formulas available to calculate sugar required based on the brix you are trying to achieve.
To lower the brix, we will add spring water to the must to “dilute” the high sugar content in the must or juice. Just beware there is a limit on how much water you can add to a must or juice before you reduce the wine quality. There are also good formulas for this adjustment too.

What is Cold Soaking?
Cold soaking, also known as pre-fermentation maceration, is a winemaking technique that is widely used in the production of red wines. It involves holding crushed red grapes at a low temperature and takes place before fermentation.
Why should I be cold soaking?
Cold soaking red grapes such as Pinot Noir, Cabernet Sauvignon, Merlot, and more has many benefits. The aim of a cold soak is to extract more aromas, aroma intensity, and color from the skins of the grapes. In red wines, it makes for a more intensely fruity and deeper-colored wine; but it also makes for a fuller wine with increased palate weight. For example, in Pinot Noir, cold-soaking extracts the softer, more supple tannins to help produce a silky mouthfeel. It also helps emphasize the lush fruit notes like dark cherry and plum. Yum!
But wait; there’s more: Firstly, time in a cold soak, even a brief one, lets a winemaker get a much better handle on the fruit at hand, enough time to get a tank thoroughly mixed, time for any raisins in the fruit to reveal their sugars, time to get more trustworthy readings on basic wine chemistry than the numbers grabbed in the rush of fruit delivery. And second, extracting some goodies early in the cycle leaves open the option of pressing slightly early and working off the last few Brix in barrel, again minimizing the influence of nasty seed tannin.
How do I do it?
It is important to maintain a chilled temperature because if the must gets too warm it can begin fermenting. To properly cold soak, you need to maintain a temperature of about 35-45 degrees Fahrenheit. This could be difficult for home winemakers without a chiller system. Try using dry ice or ice tubes ser in the wine to the wine as cold as you can. Remember, the point of the low temperature is to be sure the yeast cannot get started.
This is usually done for about 5 days, though the length of time varies according to the winemaker’s goals and the grape variety. You should add enzymes to help the extraction move along, and sulfur dioxide to inhibit unwanted microbial activity. Using inert gas to prevent oxidation is also a great idea. Inert gases, known as carbon dioxide, nitrogen, and argon are necessary for winemaking. They are used to supplant air in places where air could come into contact with the wine.

EC-1118 Wine Yeast: Product Spotlight
What makes EC-1118 so great?
EC-1118. It’s an excellent strain to be used in a wide variety of wines. This includes red and white, including sparkling, fruit wines, late harvest wines and cider. It has a strong competitive character that will inhibit wild yeasts, and restart stuck fermentation due to it’s great alcohol and sulfate tolerance. Being a very neutral yeast, it will have very little effect on the varietal character of the grape. It ferments fully, and flocculates well, producing compact lees. It has extremely low production of foam, volatile acid and hydrogen sulfide (H2S) and it ferments well over a wide range of temperatures (50 to 86 degrees Fahrenheit), making it one of the most favorable and popular wine yeasts.
Considering EC-1118 for your next wine batch? Click here to be directed to our store to purchase online, or call us at (877) 812 – 1137 to place an order with one of our associates. We can also provide a step-by-step instructional for re-hydrating your yeast and adding it to your wine. Whether you’re a newbie home winemaker or a pro, we’re here to help!
Pairing Wine with Salmon
What kind of wine should you pair with your salmon, and why?
It mainly comes down to how you prepare the salmon that really determines what wine to pair with it. Salmon is a fatty fish, so it needs a stronger wine to stand up to it. It has rich fats, making a bitter and acidic wine a good general match. Salmon itself is not acidic, but those rich fats work well in place of acidity, and if you add a citrus glaze it would make the acidity in the wine harmonize better. Salmon is naturally mild but also vibrant, its actually able to work well with many different kinds of flavors.
Deciding on a wine to go with your Salmon can be complex because of all the different options in the types of salmon and how it’s prepared, so we decided to include various types of combinations because everyone has a different taste and preference!
Pairing Wine with Salmon and how it varies with various preparation methods
It’s not usual to pair a sweet wine with salmon, though a sweet glaze can call for a semi-dry wine. Reach for a rose or even a semi-dry Riesling, as both have enough lift to help enhance the sweet glaze but also pair the sweeter elements to the glazed salmon.
Reds, whites and even a rose can work as long as they are low in tannins and higher in acidity. A fuller white wine works well with pan fried salmon which becomes heavier and firmed when prepared this way.
Heavier salmon dishes like smoked salmon or ones with creamy and buttery sauces can call for a sparkling wine. Sparkling wines have the ability to lift up those heavier flavors and textures. For smoked or grilled salmon, try a prosecco. Because the acidity will pull the rich flavors of the salmon, it will also lift the heavier smokey flavors too. For a cream sauced salmon dish, grab some Pinot Grigio. This is a dry wine with a smooth finish and has the perfect amount of structure to complement but also add a textured layer to the creamy dish.
For baked or poached salmon, a classic dry wine with medium body and high acidity like a Cabernet Sauvignon from Sonoma would be an excellent pick. This is a medium bodied red wine with heavier levels of acidity but also a smooth, fruity finish making it a great option. Also, wine aged in barrels can have a real punch of flavor which would further enrich the already rich, natural fats and fresh flavors of the salmon.

Air Fryer Buffalo Cauliflower Bites
Air Fryer Buffalo Cauliflower Bites
If you’re obsessed with wings like I am, but are looking for a healthier alternative, try these air fryer buffalo cauliflower bites! Cauliflower has a similar texture to potatoes, but without all the carbs. There are a few way you can prepare these, but I’ve been obsessed with my air fryer lately so that’s what I’ll be using for this recipe.
What you’ll need:
About 5 cups of cauliflower, chopped into florets
Buffalo Sauce – Frank’s Mild Buffalo sauce is my all time favorite!
Unsalted butter
How you’ll do it:
Spray the cooking basket in the air fryer with some non stick cooking spray
Add the cauliflower and cook at 375 degrees for 15 minutes. Toss the cauliflower and add back in for about 5 minutes if they aren’t crispy yet. (Try cooking the cauliflower in smaller batches if they come out soggy – I’ve noticed if you over pack the air fryer they tend to not crisp evenly.)
Add cold butter to the warmed buffalo sauce and add to a large bowl, and pour the sauce mixture on stop and toss to fully coat.
Serve with blue cheese dressing for dipping and carrots and celery sticks to serve on the side.
The impossible pairing:
Yes, you can pair a wine (actually, quite a few!) to go with your buffalo dishes. A slightly sweet white wine will compliment the buffalo sauce the best. Reach for a Champagne, Moscato D’Asti or a Riesling. The fruity flavors and the low level of tannins really works with the buttery spice and they also help with the heat!
Wine Barrel Care and Maintenance
Winemaking is an investment in most winemakers’ eyes. One of your most tedious but worthwhile investments will be a wine barrel. They are expensive to produce and challenging to maintain, but the impact it can have on the quality of your wine makes it worthwhile. This article will cover the anatomy of the barrel, how to clean it, and the maintenance you should familiarize yourself with if you plan on owning one.
Inspecting your barrel
The first thing you should do as soon as you receive your new (or used) wine barrel is to inspect it. You should start by visually examining the barrel’s exterior. Keep an eye out for broken chimes, dented or displaced heads, and misaligned staves. Also look for scrapes, gouges, and any torn or burred hoops. Next, you’ll need to inspect the inside of the barrel. The inside should be completely dry and free of mold. The area where the head meets the staves can be a breeding ground for mold, which usually occurs from a combination of standing water and exposure to starch used in the construction of the barrel. Lastly, observe the aroma of the barrel. The barrel should smell clean, fresh, oaky, and/or toasty. Other than sulfur, there should be no chemical odors and certainly no aroma of spoilage.
Prepping your barrel for wine
This will include one last inspection of your barrel, which is testing your barrel for leakage first. You need to rehydrate your barrel, or “swell” it to prepare it for wine, but it’ll kill two birds with one stone allowing you to inspect for any possible leaks. There are two ways to swell your barrel, the first option being the hot water/quick soak method. The second option is a coldwater/high volume soak. The only main difference is the speed of which the soaking gets done.
Hot water/quick soaking consists of filling the barrel with 3-5 gallons of filtered, chlorine-free, hot water. The ideal temperature for this would be about 180 degrees Fahrenheit. Use caution when using water hotter than this, or using high-temperature steam as this can degrade and damage the barrel. Once you’ve filled your barrel, place your stopper in the bunghole. Rotate the barrel from side to side, completely wetting the barrel’s interior. Stand the barrel upright on its side (one head facing down, the other up) and let stand for about 4 hours to rehydrate the head. Repeat with the opposite side for an additional 4 hours. During these processes, make sure to continuously check for any leakage. If there are no leaks, turn the barrel so it’s bunghole is facing toward and allow to drain and dry completely.
Coldwater/high volume soaking calls for filling he barreling completely with filtered, chlorine-free, cold water. Once you’ve filled the barrel completely, place your stopper in the bunghole and let the barrel stand for about 24 and 48 hours. Once no leaks are present, empty the barrel and allow it to drain and dry completely.
If your barrel continues to leak after multiple swelling attempts
If after either of these methods are complete the barrels still exhibit leaks, repeat the swelling process as it’s possible it just needed more time to swell. There are some additional methods of swelling you can attempt that are more aggressive but can possibly help seal any leaks.
The submerging method:
We have found that sometimes soaking the interior and exterior of the barrel simultaneously can help to get it swelled. Start by placing the barrel upright on one head in a large container. Fermentation tubs work great for this. Next, fill the barrel halfway until water is seeping from the bunghole, then fill the container it’s in up to the same bunghole. Let the barrel sit overnight, then remove all water from the barrel and container, flip the barrel onto its other head and repeat the process. Once emptied, use the cold water method and check for any leaks.
The hoop tightening method:
The hoops on a barrel can become loose when it becomes dry. Using a hoop driver, or if no hoop driver is available, a cold chisel to hammer the hoops toward the center of the barrel. Workaround the barrel, hammering firmly at around one-quarter increments of the circumference. It may be necessary to remove the hoop nails to allow the hoop to slide tighter onto the barrel.
The Barrel Sealing Wax method:
Beeswax can be used to seal small leaks. The first step is to mark any leaks with a pencil or chalk. To properly apply sealing wax, first make sure the barrel is dry. Next, gently sand leaking areas with rough sandpaper. Knead a small piece of beeswax in your hand and work the wax into the area using a putty knife. Beeswax will not change the flavor of your wine and is completely safe to use.
After several attempts, if your barrel continues to leak, it is important to call your sales rep immediately. Empty the barrel, allow it to drain, and completely dry. Next, you have to treat each barrel with 10-20 grams of sulfur sticks (or the equivalent gas form) and re-insert the stopper. This will ensure that you are still maintaining the integrity of the interior of the barrel.
Storing your barrels
Ideally, barrels should always have wine in them. If you are in between winemaking projects though, or you’re waiting for harvest, there are a few guidelines you should follow when storing your barrels. If you are storing a new barrel, store in a cool, humid environment. Some new barrels arrive with their plastic film still on them – if yours does, keep that film on if you plan to store them for a significant amount of time. The process of storing a used barrel requires a bit more work.
If you are ready to empty your barrel, empty it and wash the barrel out with hot water until all of the deposits and tartaric crystals have been dissolved and emptied. Repeat if necessary. If you have access to larger volumes of hot water, fill the barrel completely and let sit overnight. Once emptied, rinse the barrel with cold water and let it dry with the bunghole facing down. Allow to completely dry, and then burn sulfur sticks or discs in the barrel and place stopper in the bunghole. This burning treatment should be repeated every six weeks or so until you are ready to use the barrel again. Finally, store your barrels in a cool, humid environment.
Other tips and tricks for maintaining your barrel
Never leave water in a barrel for more than two days. If the swelling process takes longer, empty, and refill the barrel with fresh water to avoid mold and spoilage micro-organism growth.
A full barrel is a happy barrel! If possible, try to refill your barrel immediately after it has been emptied and cleaned. This way you will never have to re-swell it and there is much less opportunity for bacteria and other spoilage organisms to get into the barrel.
Never use chlorine in or around a barrel, or any winemaking equipment for that matter. TCA, also known as cork taint, can infect much more than just corks. A barrel is a vulnerable place for TCA to be absorbed into due to the spores, molds, and natural phenolics of the wood.
When in doubt, throw it out – or repurpose your barrel for something other than winemaking. If you suspect that there are spoilage organisms in your barrel even after you have tried ozone/steam/proxycarb, (you can find info on these here) err on the side of caution and retire it. You can ruin any future wine you put into such a barrel and it can possibly infect the rest of your winemaking equipment if they are stored near them. Barrels can be repurposed into planters, furniture, and more!

Potassium Metabisulfite: Product Spotlight
What is Potassium Metabisulfite?
Potassium Metabisulfite is an antioxidant and sanitizer, and has several uses in winemaking. After crushing and de-stemming, it is used to help kill off any spoilage bacteria and natural yeast that may be present on the grapes or equipment. It also helps to preserve wine, specifically protecting it against oxidization.
Throughout the entire winemaking process, it’s important to measure your SO2 levels and adjust as needed to improve and lengthen the preservation of your wine. The exact amount needed to be effective is entirely determined by the pH of the wine. Also, free SO2 levels fall faster in a wooden barrel versus in glass or stainless steel tanks, so make sure you manage your SO2 levels very closely.
How do I use it?
If you are adding Potassium Metabisulfite to your must, the proper amount is ¼ teaspoon per 5 gallons of must. If you are making an SO2 sanitizing solution, add 8 teaspoons for every 1 gallon of water. Place into a spray bottle for quick and easy use. After cleaning your equipment and again before use, spray the solution generously and shake off/let any extra solution drip dry.
Potassium Metabisulfite has a shelf life of about one year if you are using it to add to your wine. If you have some that is over a year old, no worries! It still functions as a sanitizer, just make sure you separate and label each to avoid any mix ups.
Where can I get it?
You can find and purchase Potassium Metabisulfite here. Need assistance in using SO2, whether adding to your wine or sanitizing your equipment? Give us a call at (877) 812 – 1137 to speak with a sales associate who can help you!

A Guide to Malolactic Fermentation
Malolactic Fermentation, also known as Secondary Fermentation or “Malo”, is the process in which Malic Acid in the wine converts to Lactic Acid.
What is Malolactic Fermentation?
As stated above, it is the process in which Malic Acid in the wine converts to Lactic Acid. The primary role of Malolactic Fermentation is to deacidify the wine which affects the sensory aspects of wine, making the mouthfeel smoother and it adds complexity to the flavor and aroma of the wine. The deacidification of the wine happens by converting the harsh diprotic malic acid into the softer monoprotic lactic acid. Nearly all red wines go through Malo while only a few whites, like Chardonnay and Viognier, do. One way to recognize if a wine has gone through Malo is if it has a creamy, buttery mid-palate texture. The buttery flavor comes from diacetyl, a by-product of the reaction.
What is Diacetyl?
Diacetyl is a flavor metabolite produced by lactic acid bacteria known as Oenococcus Oeni. Oenococcus Oeni is the main bacteria responsible for conducting Malo, due to its ability to survive the harsh conditions of wine. It is responsible for the production of the sensory aspects noted above. Malo can happen naturally, though often inoculated with the bacteria culture to jumpstart the process.
When does Malo take place?
Malolactic Fermentation can happen in two different ways, during primary fermentation or after. Amid fermentation, it is Co-Inoculation. After fermentation, it is Post-Fermentation Inoculation. Inoculation that takes place after alcoholic fermentation is the most common practice. When you add bacteria cultures like MBR31 after fermentation is complete, it jumpstarts the Malo process. Co-inoculation takes place at the start of alcoholic fermentation, which allows winemakers to focus on other things such as the improvement of flavor development.
What are the signs that Malo is in progress, and how do I know if it is finished?
The best way to identify malo in progress is bubbles! The malolactic activity can be detected by the presence of tiny carbon-dioxide bubbles. When the bubbles stop, Malolactic Fermentation is complete. This can take anywhere between one and three months.
What are the benefits of each method?
Firstly, the benefits of post-fermentation inoculation include better control of the start time duration of Malo. Lessened biogenic amine production leaves the wine unprotected by sulfite for a limited amount of time. This allows less potential for spoilage by other organisms. It reduces the incidence of excessive volatile acidity and enhances flavor profiles and complexity. The benefits of co-inoculation include lower levels of the inhibitory alcohol that are present at the start of Malo, and no need to apply external heating to the ferment due to the heat generated by the yeast fermentation. This results in faster completion of Malo. This means the wine can have sulfite added earlier and reduces the potential for the growth of spoilage organisms. Finally, a bonus is that bacteria added at the start of the yeast fermentation encounter a nutrient-rich environment.

Fermenting Tubs: Product Spotlight
Fermenting Tubs: Product Spotlight
Fermenting tubs: we sell a variety of winemaking products, including tubs specifically made for fermenting. Why is a fermenting tub one of the best investments you can make? Choosing the proper vessel to ferment your wine in is extremely important as it effects the quality of fermentation.
What’s so special about our fermenting tubs?
Our fermenting tubs are made of food grade plastic. Did you know if you used a non-food grade plastic pail or tub to ferment your wine in, you can actually poison yourself? This is due to the plastic actually seeping into your wine while it heats up during fermentation! Wild, right?
What are the benefits of using a fermenting tub aside from not being poisoned?
Aside from not being poisoned by your fermenting tub, the way our fermenting tubs are engineered makes a big difference than per say a normal drum or bucket. Our pails gradually get wider going from the base up, giving the must more surface area to breathe. This also helps with any cold spots you may have. More surface area equals better fermentation, better fermentation equals better wine, and we all know what better wine equals!
Do your fermenting tubs come with lids?
Our fermenting tubs do come with lids (sold separately) however; we actually recommend simply using a bed sheet draped over the tub. Why? Let’s revisit the need to let your wine breathe: not providing enough oxygen to your wine can actually give it a rotten egg smell, this is due to volatile sulfur compounds developing in the enclosed space between the wine and the lid. Not only do you want to avoid rotten egg smelling wine, you also don’t want your tub to explode. A closed fermentation tub becomes an incubator, trapping heat with the gasses and BOOM! Now you have must everywhere AND your winemaking room smells like rotten eggs. Yuck. Using the bed sheet instead of the lid will prevent this too.
If you’ve decided to invest in a fermenting tub, visit our store to pick yours up or give us a call at (877) 812 – 1137 to place your order over the phone with one of our sales associates. You can view the sizes and specs of our tubs here.
Caramel Chocolate Chip Cookies
Caramel chocolate chip cookies are a treat definite to make you swoon. The best part? This can be a quick, easy recipe so you’ll be enjoying these sweet treats in no time!
First, you’ll need the ingredients!
2 cups of all-purpose flour
1 teaspoon of baking soda
1 teaspoon of cornstarch
1/2 teaspoon of salt
1/2 cup of butter
1/2 cup of brown sugar
1/2 cup of granulated sugar
2 large eggs
1 & 1/2 teaspoons of vanilla extract
1 cup of chocolate chips (I usually use milk chocolate, but you have the freedom to pick which chocolate you like more!)
1 cup of caramel chips
1-2 Tablespoons of sea salt (coarse)
Next, combine and bake!
Firstly, in a medium bowl, combine the flour, baking soda, cornstarch, and salt. Secondly, beat the butter and sugars together in a separate bowl. You can use a stand mixer with a paddle attachment or a handheld mixer on low speed until combined. Thirdly, Beat the eggs and vanilla in a small bowl until combined and then stir into the flour mixture until well blended. Fourthly, Add chocolate and caramel chips, preheat your oven to 350 degrees, and place cookie dough onto a baking sheet spaced two inches apart. You can use a tablespoon or small ice cream scoop to measure out the side of each cookie. Press sea salt on the tops of each cookie. Finally, bake for 10-12 minutes or until lightly browned and allow to cool.
Wait, nothing is complete without a glass of wine…
Have you ever made Port before? It pairs perfectly with these cookies! The rich textures, fresh fruit factors, hints of chocolate, and sweet profile of Ruby Port makes it a no-brainer for pairing with many kinds of caramel, milk, and dark chocolate choices.
How to Make Port Wine:
You can make port from existing wine by adding grain alcohol, everclear, or brandy. First, determine the alcohol level you want your port to be. Second, use Pearson’s Square to determine how much brandy you need to add. Third, add that amount of brandy and sugar adjustment to the wine.
