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.

Wine Grape Spotlight – Malbec
Malbec is a grape variety with a deep, inky color, producing dry red wines that boast robust tannins and a long, smooth finish.
Where is Malbec from?
Malbec was almost exclusively grown in France, where it played a primary role as one of the main Bordeaux grapes. The climate and pests in France did not allow for Malbec to perform to its utmost potential. Struggling to thrive, growers saw it as weak, finicky, and susceptible to disease as well as rot. It is mainly associated with Argentina and Chile now because it thrives there. It took well to the climate, excelling in the high elevation and heat, making it one of the most widely planted grapes. In the United States, you can find the majority of wine grape plantings in California, yet Malbec only makes up for 0.5% of those plantings.
Malbec Characteristics
This grape can yield a wide range of fruit aromas that vary widely depending on the climate they are grown in. Cooler climates like France and Washington state yield black cherry, raspberry, and plum aromas. For warmer climates like Chile, you’ll get more blackberry, blueberry, plum, and black cherry. They’re juicy and jammy, with notes of vanilla, tobacco, dark chocolate, and oak. They have medium acid and moderate levels of tannins. Chilean Malbec’s boast with red fruit flavors like cherry, raspberry and have floral and slight earthy notes.

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?

A Guide to Chardonnay
Chardonnay is a white wine grape that originated in the Burgundy wine region of eastern France. We source our Chardonnay wine grapes from 3, high quality, and sustainable appellations in California. This includes Suisun Valley, Lodi, and Central Valley. These regions produce a range of outstanding high quality to premium luxury wine grapes for the best value.
Suisun Valley, California
Firstly, Suisun Valley Chardonnay tends to yield beautiful notes of honeysuckle, green apple, and lemon tied into a welcoming nose. It is full-bodied and lush on the palate featuring tropical flavors of pineapple, peach, and bright citrus. It also has a clean and pleasant finish. We recommend fermenting in a stainless steel fermenting tank using QA23 wine yeast. This is perfect if you’re aiming for that tropical profile in your Chardonnay.
Lodi, California
Secondly, If you’re looking to make a beautifully balanced wine with lovely notes of pineapple and citrus, that mingles with notes of sweet vanilla custard finishing with just the right amount of silkiness and acid, we recommend the Lodi Chardonnay. We also recommend fermenting with D47 wine yeast in a French oak barrel. When you are fermenting in a barrel, it’s best to use MBR31 to allow your Chardonnay to go through Malo-Lactic Fermentation. This will achieve those silky and buttery finishes.
Central Valley, California
Finally, If you’re drawn to the Lodi Chard characteristics but you’re looking for more complexity, try the Central Valley Chardonnay. It has the potential to yield fresh tropical fruit, pears, and peaches along with custard cream flavors leading to a creamy, soft, and mouth-filling finish. For these results, we recommend fermenting in a stainless steel tank or fermenting tub with VIN13 wine yeast and aging in a French oak barrel. Inside the barrel, it should undergo Malo-Lactic Fermentation with the use of MBR31 and will yield that layered complexity you’re craving.
