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.

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.

A Guide to Cabernet Sauvignon
What is Cabernet Sauvignon?
Known as the king of red grapes, Cabernet Sauvignon enjoys the same regal status in California as it does in its native home of Bordeaux, France. Californian Cabernet Sauvignon tends to be more fruit-forward and mellow, with rich dark fruit notes. The most common aromatic and flavor components found in this varietal are plum, black cherry, blueberry as well as warm spice, vanilla, black pepper, and tobacco. Aside from being known for its dark color and full body, it’s known for often being over 13.5% in alcohol content. The average alcohol content of a Cab from California floats around 14.5%. At Musto Wine Grape we carry a variety of Cabernet Sauvignon grapes from multiple AVAs in California, as well as all of the yeasts, nutrients, and equipment you’ll need.
What kind of yeast should I use when making Cabernet Sauvignon?
*Note that full expression of the desired characteristics for any of the following yeast strains is based on proper care and feeding if the yeasts, along with using quality fruit and good winemaking practices. It is also strongly recommended that Go-Ferm and Fermaid-K are used as well as temperature management throughout the entire fermentation. As always, if you need assistance with any part of your winemaking process, do not hesitate to reach out to us at sales@juicegrape.com or give us a call at (877) 812-1137 to speak with someone who can assist with any product recommendations, procedures, or problems.
BM45 yields a big mouthfeel, notes of cherry liquor, rose petal, jam, plum, berry as well as earthy and spicy elements. It offers color stability and helps to minimize vegetative characteristics.
BDX is an all-around great choice for berry, plum, and jam characteristics. It has a moderate fermenting rate and offers good color retention. By re-enforcing existing tannins, it develops structure in the wine. Because of this, we advise to not use with unripe fruit.
RP15 emphasizes the berry aspects of the fruit, along with color stability, increased mouthfeel, and agreeable tannins.
D254 yields a big mouthfeel and rounds tannins as well as intense fruit. It has a focus on berry and jam characteristics, but more so of dried fruit than fresh. It’s also great for color stability and adds body to blends.
D80 offers big volume and fine grain tannins. It is great for encouraging more positive tannin intensity to a blend.
Where do you source your Cabernet Sauvignon from?
We offer Cabernet Sauvignon from multiple AVA’s within California and Washington:
Lanza-Musto Vineyards in Suisun Valley, CA (Valley, 169, 15, and Koch)
Mettler Family Ranch in Lodi, CA
Napa Valley, CA
Washington State (Clone 33)
Sonoma County, CA (Chalk Hill)
Amador, CA
King’s River, CA
Paso Robles, CA
Central Valley, CA
Is there a certain winemaking procedure specific to Cabernet Sauvignon?
You can follow our Red Wine Grape Procedure which you can find here, if you are using juice you can find the procedure here and if you are using frozen must, here. The procedure is standard for making red wines, but using the proper yeasts and nutrients specific for Cabernet Sauvignon and consistent monitoring will have the biggest impact on your final wine.
Where can I buy grapes, juice, or must?
At Musto Wine Grape Company, all red grape varieties are available in 36lb cases, in frozen must by request, or in 6-gallon fresh juice pails. For Sterile Juice options that can be shipped year-round and without refrigeration click here.

Peach Prosecco Popsicles
Peach Prosecco Popsicles
One of our all-time favorite summer treats is popsicles. You can make popsicles from pretty much anything, and they are perfect to cool down on a hot summer night! Not to mention, throwing in some fresh fruit and wine into a popsicle is one of the most genius inventions. We’ve got an easy peach prosecco popsicle recipe waiting for you, so keep reading!
Peach bellinis are a favorite cocktail! If you like them as well, you’re in luck because these popsicles are basically peach bellinis on a stick.
What you need and what to do:
You’ll need to buy some peach puree or make some yourself, which isn’t difficult at all. To make your own, grab 3 ripe peaches. Bring a pot of water to a boil, and place the peaches inside for about 1 minute. After about a minute, immediately remove the peaches from the boiling water and place into a bowl of ice water. Let the peaches sit in the cold water for about a minute or so, and you’ll be able to peel the skins off with your fingers. You can also use a knife if that’s your thing. Once you have removed the skins, you can begin to slice the peaches and remove the flesh off of the pits. Next, you’ll place the peach slices into a food processer or blender and blend until smooth. An easy alternative would also be to buy a bag of frozen sliced peaches if you want to skip the boiling and peeling. If your peaches are not sweet to your standards, feel free to add some sweetener to give it a boost. Mix your puree with Prosecco and pour it into popsicle molds. You can freeze overnight, or if you prep in the morning they can be ready for the late-afternoon.
Enjoy with family, friends, or a good quarantine movie night.

A White Wine Drinker’s First Shot at Tasting Red Wines
A White Wine Drinker’s First Shot at Tasting Red Wines
Christina has given me a few bottles of wine to stretch my tasting abilities and educate my nose and taste buds. Here’s how it went! My go-to’s have always been a sweet white or rosé, I haven’t really ventured out with reds mostly because the first red I had was gross and I figured all red wines were like that. I was definitely wrong! Note, I am a beginner at tasting red wines so these are very amateur notes.
The first wine Christina gave me to try was a 2018 Sonoma Cabernet Sauvignon.
Ashley: I smell cherry the most, with kind of a plumy smell, and maybe prune; but cherry was the first thing I smelled.
Christina: Great! Next time think about what kind of cherry – Black cherry? Red cherry? Ripe cherry?
Ashley: It has a nice deep purple toned color to it and has no floaters.
Christina: Good, the browner the tinge of the wine the older the wine is.
Ashley: There’s no carbonation or fizz – I’m used to the wines I drink having bubbles or a little fizz to them.
Christina: Good! Fizz really only happens if the wine wasn’t taken care of or if it is a sparkling wine.
Ashley: It makes my mouth pucker at first but doesn’t leave my tongue dry for long, it goes away quickly.
Christina: If you salivate that means the wine is high in acid, if it dries out your mouth that means tannins are present. Sometimes people use the word “pucker” referring to both. Next time try to think about what is causing that feeling? Is it the salivation in your mouth like if you just tasted a bitter lemon, or is it the drying out of your mouth/chalky feeling in your mouth?
Ashley: Alcohol is pretty high!
Christina: Glad you picked up on this! Most Cabernets from Sonoma and Napa California are higher in alcohol.
Ashley: Kind of tastes like a Cigar.
Christina: That usually has to do with barrel aging or growing region; you find this characteristic a lot in red wines from Chile and Argentina. If you find it in a CA wine it’s usually due to barrel aging in a heavy toasted barrel.
Ashley: I pick up black pepper but it’s not strong.
Christina: I’m glad you thought about the type of pepper. That’s great. Try to be as specific as you can be.
Ashley: It’s easy to swallow but gives a hot feeling in my chest, kind of like if you drank something hot with cinnamon.
Christina: That is an indicator of high alcohol. Good job picking up on that!
Ashley: Kind of a charred taste, like eating the black burnt part of a marshmallow or pizza crust.
Christina: This has to do with the aging process of this wine. It sounds to me like it was a little “tight” and could have been laid down for a few more years so the balance of fruit and earth could shine through. Great specific description of what you tasted.
Ashley: It’s not something I would drink on a regular but it wasn’t terrible.
Christina: Great, you are figuring out what you like. Think about what type of food you would have this with and if it would change your perception of the wine.
Next was a 2015 Cabernet Sauvignon 169.
Ashley: This one gave a rush of burning through my nose upon first sip and swallo2. It reminds me of the sensation you get when you burp through your nose
Christina: This means it’s got a decent amount of alcohol in it.
Ashley: I definitely taste black pepper with this one; it’s very smooth, smoky and earthy. Kind of when you eat a vegetable right out of the garden without washing it and it has like dirt on it haha!
Christina: Haha those are good descriptors!
Ashley: It doesn’t seem to be too high in tannins, after a few sips my tongue started to dry out, but right off the bat I didn’t feel much dryness.
Christina: This means the tannins were balanced, soft, and supple. That’s a good thing for red wines.
Ashley: I also got black cherry and plum in this one, though it is dry it kind of gave me the impression that it was going to be slightly sweet, because it smells like it but it definitely was not sweet.
Christina: This happens a lot with dry red wines; you get sweet notes on the nose but not on the palate. Good job picking up on the fruit aromas!
Ashley: Overall this is the first red wine I didn’t hate and would actually drink again! I definitely see myself enjoying it with a steak for dinner.
Christina: Wow that’s great!
The last wine I tried was a 2018 Chilean Malbec.
Ashley: Very earthy, I got that same dirt taste from the cab but it’s way more prominent with this one.
Christina: Good descriptors!
Ashley: It’s also very dry, significantly drier and higher in tannins than the cab 169. It dried my tongue out on the first sip and kind of made my throat feel dry too.
Christina: Perfect! Now you know the difference between medium/balanced tannins and high tannin wines.
Ashley: I do pick up on a black pepper, and get some licorice, some bitter blackberry as well. But the dirt taste is what my mouth captures first and sticks throughout the whole experience.
Christina: Okay good observations and descriptors!
Ashley: I wasn’t a fan of this one because the dirt taste was all I could focus on.
Christina: Good! You know now that you don’t like high tannin earthy wines.
Reflection
The Cab 169 from Suisun Valley, CA definitely left an impression on me and I am going to explore with other wines from the similar region and see what else I can take a liking to! Overall this was a fun experience and I look forward to experimenting and broadening my wine horizons. A big thanks to Christina for being an awesome teacher, it’s looking like I’ll be a pro at tasting and winemaking in no time!

Milk Loaf Recipe Using 71B Yeast
Have you run out of ideas for what to keep yourself busy with during quarantine? We’ve decided to experiment and the results were delicious. Using 71B yeast and Scott Lab’s recipe for milk loaf, we put our baking skills to the test and had a whole bunch of fun doing it!
Prep time runs just about two and a half hours, and bake time is about 25 minutes so this will surely keep you busy!
Here’s what you’ll need (for a yield of 2 loaves. If you’d like more increase ingredients as needed):
- 4 cups of bread flour
- 2 teaspoons of salt
- 1 tablespoon of sugar
- 2 sachets (9 grams) of Lalvin 71B Yeast (Don’t have this on hand? No worries! We have it in stock. Give us a call/visit and we’ll get you what you need!)
- 2 tablespoons of butter
- 1 cup warm whole milk
- 1 cup tap water
Here’s what you’ve got to do:
- Mix all dry ingredients together in a bowl. Then, add butter, milk and water. Mix everything together with a spatula.
- Once the wet ingredients have been absorbed, remove dough from bowl and transfer to a counter or workspace.
- Extensively knead the dough by stretching and folding it repeatedly. Once the dough is smooth and slightly shiny, divide it into two pieces. Cover each with plastic and let rise for 40 minutes.
- Flatten each piece of dough and roll into the shape of a football. Let the dough rise again for another 40 minutes.
- Place the dough into a bread pan (about 6”-7” long, 3.5” deep) and cover with plastic and allow to rise for another 60 minutes.
- Bake in a pre-heated oven at 420 degrees F for approximately 25 minutes.
- Let cool and enjoy!
