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.

Cleaning vs. Sanitizing in Winemaking
What is the difference between Cleaning vs. Sanitizing?
This is a discussion we have with customers constantly. Cleaning your equipment means that you have removed all of the visible dirt and residue on your equipment. Sanitizing means you have treated your equipment with a chemical solution that will eliminate, or prevent the growth of spoilage organisms. You MUST clean your equipment before sanitizing the equipment, since you cannot properly sanitize equipment with visible residue on it.
Below is a video from our online classes – WinemakingInstructions.com that talks about and shows you step by step how to clean and sanitize your equipment.

Special Primitivo coming from fifth generation farmer Berton Costamagna
Special Primitivo coming from fifth generation farmer Berton Costamagna
There is something very special about walking through this Primitivo vineyard for fifth generation farmer Berton Costamagna. “Since 1902 my family has been here in Lodi farming these wine grapes”, says Berton. “To think that my Nono (Great, Great, Great Grandfather) had the foresight to start a farming adventure back then, by planting his first vineyard of Primitivo here, and to see where it is now, is so inspiring to me.” With its sandy loams, and ideal climate, farmers back then quickly saw the potential for growing wine grapes in Lodi, in the heart of California. Fast forward 120 years, and Lodi California has come to be known as the Zinfandel Capital of the World, and is now one of the top producing AVA’s in the world. The Costamagna family has continued farming their family’s clone of Primitivo for all these years for wineries and home winemakers to enjoy with their families. “These grapes make for a great wine, but what is truly special, is these grapes connect us to the hard work, traditions, and memories of my family before me. My hope is that folks can make as many memories drinking the wine from these grapes as our family has made farming them.” 🍇🍷 We can’t wait to receive these grapes from the Costamagna Family!

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 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!

Black Muscat: A Grape by Any Other Name
The oldest genetically traceable family of grapes is the Muscat family. Over the centuries, the grape has traveled around the world and transformed itself through many genetic mutations. One of the most well known genetic crosses of the original Muscat grape is the Black Muscat. Black Muscat is a cross of the Schiava Grossa and the Muscat of Alexandria. The grape has very large, plump berries, with white flesh and black skin. The grape has intense, sweet floral and candy-like flavors.
Black Muscat can be used for a very wide variety of wine making purposes. It can be pressed to produce a white juice, that has been used in famous dessert wine productions as well as left on the skins to produce a flavorful rose or red table wine. It is popularly used for table wine production in California, China, and Eastern Europe. Quady Winery in California has gained fame and many acclimations over their dessert wine, Elysium, produced from the Black Muscat grape. The intense florals and sweet fruit flavors that are found in the unprocessed grape, translate in the finished wine product. Big flavors of raspberry jam and candied citrus make the wine deliciously sweet with enough acidity to create a harmonious balance. Because the wine can be made in so many different styles, the winemaker has many choices to control the outcome of the final product. If creating a dessert style wine, beneficial yeast strains would be Vin 13 or R2 to promote the complex floral aromatics. If creating a rose or table wine, QA23 or 71B yeast strains will help to promote aromatics and to capture the ripe red fruit flavors. Skin contact time will be critical; a few hours on the skins will produce a flavorful rose and then full maceration/fermentation on the skins will create a fruit forward table wine.
Musto Wine Grape has had such wonderful results with this grape, that Frank Musto has planted his own fields of this varietal. The vines are coming up on their 20th birthday, generating large but complex fruit and excellent yields. Frank Musto’s Black Muscat has started being harvested and is arriving in Hartford currently. Brix levels are averaging in the mid 20’s with smooth acidity. We are looking forward to making a fruit forward rose this year with some of the fruit. It is exciting to create a new style of wine with such an ancient, treasured strain of grape.

How to Add Body without Ever Hitting the Gym, meet the Lagrein grape…..
As winemakers, we have all had a red wine that feels a little thinner in the mouthfeel than we would care for. It may feel thin bodied and slightly flabby. How does a winemaker address this issue in their wine? Unlike people, we can’t send the weak bodied wine to the gym to bulk up, but we can introduce the wine to Lagrein. Lagrein is a red wine grape that originates from the northern valleys of Italy. It has been used to create very aromatic rosés and incredibly full bodied red wines. It has a higher level of acidity and a lower pH factor than many red wines, making it an excellent blending wine. When vinified on its own, Lagrein has a lot of intense, chewy tannins and flavors of plum, tobacco, and an earthy minerality.
When making a stand-alone Lagrein, (or to be used in a blend later), it is suggested that the winemaker may choose to have a limited maceration time for this grape variety. The important and prevalent grape tannins are hydrolysable and will be extracted into the must within the first few days of fermentation. The stronger, bitter seed tannins will be extracted in the accumulating ethanol later on in the fermentation, giving cause to the winemaker for an early pressing. BDX yeast strain will help to create a smoother and rounder mouthfeel, given its propensity for soft tannin extraction. Another excellent yeast for this varietal would be D80 as it will enhance palate volume, finer tannin sensation, and brings out the spicy flavors within the Lagrein grape. Fermentation aids such as Booster Rouge and Opti-Red will help to lock in the color and preserve the longer chain, smoother grape tannins with in the Lagrein grape. The winemaker can chose to add oak dust or fermentation tannins, but with the tannic intensity of the grape, it may not be as crucial as with other varietals. We always advise to use a complete nutrition program throughout fermentation, including the use of Go-Ferm, Fermaid O, and Fermaid K. This will help avoid any stuck fermentations and off aromas.
Due to its intense tannic structure, the Lagrein grape is an excellent grape to blend with other wines to help build up their tannin structure. The winemaker can chose to add in a small percentage at crush to naturally fortify their primary varietal with additional tannins or to ferment a batch of Lagrein separately and then blend into other wines, post fermentation to add to their structure or mouthfeel. With its bright acidic character and higher tannin content, it can greatly add the attributes to any red wine. Having a small amount of Lagrein wine in the winery, maybe the perfect finishing touch to some of your other wines. It can add such strong structure and body to a red wine blend, it can be a useful “secret ingredient” to fortify the body of red wines. Incorporating Lagrein, your wine will feel like it has “hit the gym” without ever having to leave the winery. If only it were that easy for the rest of us!
2018 Chilean Harvest Update
This year’s growing season should produce some intense and complex wines!
We are very excited and fortunate to be sourcing our Chilean grapes and juices from the “Heart of the Chilean Wine Industry” known as the Curico Valley. Curico has been a wine grape growing region since the 1800s. With its fertile soil, microclimates, and the ability to grow over 30 different wine grape varieties, it’s no wonder this prestigious region is considered the heart of the wine industry.
Soil Content: Sand, clay, decomposed granite, and volcanic-alluvial.
The second region we will be sourcing from is the Colchagua Valley. The Colchagua Valley is known for growing bold red wines, such as Carménère, Cabernet Sauvignon, Cabernet Franc, and Syrah. It has a mediterranean climate and is located along the southern end of the Rapel Valley. This topography creates a climate that receives around 23.3 inches of rainfall per year and little to no rainfall during their summer months. This helps keep the grapes safe close to harvest and ensures that the grapes are fighting for water therefore creating a more intense fruit.
Soil Content: Sand, decomposed granite, and clay
This year’s harvest has gotten off to a great start. The white grapes are coming off the vine and will be in transit soon. Our early red grapes such as Pinot Noir and Merlot will start harvesting around March 30th.
Arrival Dates: White grapes should arrive around the last week in April and the red grapes should start to arrive around the first week in May. Get your crushers ready!
Grapes Still Available: Carmenere, Chardonnay, Pinot Grigio, Sauvignon Blanc, and Viognier
Sold Out: Cabernet Sauvignon, Cabernet Franc, Malbec, Merlot, Petite Verdot, Pinot Noir, and Syrah
Fresco Juices Available: Cabernet Sauvignon, Carmenere, Merlot, Malbec, Chardonnay, Sauvignon Blanc, Viognier, Chardonnay/Semillon Blend
Yeast suggestions for the following grapes via Manuela Astaburuaga
Yeast suggestions for the following grapes via Manuela Astaburuaga. Manuela is the enologist at “Correa Albano” and has studied in both France and New Zealand. Her family also owns many of the vineyards we source from.
- Sauvignon Blanc – For the SB the most important thing is the yeast that express the thiols aromas. Try VIN13 to bring out such thiol aromas like tropical fruits.
- Carmenere & Merlot – Try a yeast that expresses the black fruits like CSM
- Cabernet Sauvignon –You want the fruit and earthiness to shine. Try D254, BM4X4, or CSM. Maybe think about blending yeasts for more complexity!
- Pinot noir – RC 212 is one of the best yeasts for Pinot Noir.
Manuela’s Favorite Blend: Merlot-Carmenere
Why does Sauvignon Blanc wine taste so good from Chile? (According to Manuela)
- “The different temperature between day and night is very important to the aroma expression, we have that kind of climate in our Valley (Curicó) so our SB is very aromatic and with a good acidity. We ferment at 58-50ºF to preserve the aromas.”
