Product Spotlight: CSM Yeast
Product Spotlight: CSM Yeast
CSM yeast was derived from Bordeaux and helps create a vibrant aromatic profile. CSM aids in adding complexity to the palate and pairs well with malolactic fermentation.
Why you want to use it:
It’s the perfect yeast for the Chilean fruit. It reduces vegetal aromas, adds complexity, stabilizes color, and helps increase the aromatic profiles of berries and spices.
Use Tips:
Fermentation starts quickly with this yeast. Be prepared to see Brix drop 24 hours after inoculation. It can stand up 14% ABV and can handle temperatures from 59–90°F. However, I highly suggest keeping your fermentation temps lower than 75°F. Once you hit 80°F you lose aromas and “burn off” flavors. Keeping your wine between 59–75°F during fermentation is a best practice.
You also want to use nutrients when using CSM; nutrients such as Fermaid-O and Fermaid-K. CSM tends to produce H2S (rotten egg smell) if there aren’t enough nutrients during fermentation.
Avoid cold shocking the yeast at inoculation. You’ll want to get the must and the yeast starter within a few degrees of each other before pitching the yeast starter. But without temperatures falling lower than 55°F. Temps below 55°F could stall fermentation and/or kill the yeast.
Goes best with:
CSM was cultivated to help ferment Cabernet Sauvignon, Cabernet Franc, Grenache, Merlot, Sangiovese, Petit Verdot. However, we have seen it used on Carmenere, Malbec, and Syrah from Chile with great results.
Dosage:
6gm/gals
Flavor Profile:
Cherry pit, raspberry, blackberry, spice, violet, bark, and sweet pepper

2023 Chilean Winemaking Harvest Update
2023 Chilean Winemaking Harvest Update
{above photo from our trip to chile a few years ago}
Hello, Winemakers! It’s time to get ready and prepped for the Chilean grape and juice arrival. The Chilean Winemaking Season starts in early April and ends in May. Our growers have planned to start harvesting white wine grapes around March 15th and red grapes around March 23rd. Once on the boat, we will have a better update on delivery timing.
Musto’s 2023 Chilean Offerings:
Chile Grapes: Cabernet Sauvignon, Cabernet Franc, Carmenere, Malbec, Merlot, Petite Verdot, Pinot Noir, Syrah, Chardonnay, Pinot Grigio, Sauvignon Blanc, and Viognier
Chilean Juice: Cabernet Sauvignon, Cabernet Franc, Carmenere, Malbec, Merlot, Petite Verdot, Pinot Noir, Syrah, Chardonnay, Pinot Grigio, Sauvignon Blanc, Viognier, and Muscat.
Chilean Viticulture:
Chile is the same latitude as northern California! Chileans can grow many different types of grapes here, just like in California. The cooling influences they receive from the Pacific Ocean, the Andes Mountains, and the warm and plentiful sunshine attributes to their wine-growing success. Their warm Mediterranean climate helps the grapes to ripen. The Humboldt current, flows up from Antarctica, along the Chilean coast, pushing the cool air inland by the wind patterns. This cooling effect helps cool off the grapes while they mature. Colchagua and Curico Valley both benefit from this ocean influence, which allows these regions to produce grapes from fertile soil for wines that are gaining premium reputations.
The Curico and Colchagua Valleys have some of the best soils in Chile, composed of mostly sand, clay, decomposed granite, and volcanic-alluvial. These regions only receive around 23.3 inches of rainfall per year and little to no rainfall during their summer months. The grapes are safe as harvest approaches, and the weather ensures that the grapes are fighting for water and creating a more intense fruit.
What are Brix?
The harvest is based on sugar levels in the grapes. This information comes from a simple measurement called degrees brix (also known as specific gravity). It’s important because it tells us how much water is present in our must (the mixture of crushed grapes and yeast starter). The lower this number is, the more concentrated or “dry” your wine will be when finished fermenting. The ideal Brix levels for red wines is 23-25 Brix, and for white wines 21-24 Brix.
How are the grapes harvested?
The grapes are handpicked. The pickers walk through rows of vines looking for clusters of ripe fruit to cut off with long-handled knives called “cortadores.” They then gently place these into plastic tubs where they’re carried back to trailers parked nearby–a process that takes place over several days (usually during the morning). Once all of this has been completed successfully, we begin our shipping process!
How do you know when to harvest the grapes?
The wine grape harvest is based on sugar levels in the grapes: if they’re too low you can’t make good wine; too high and it will taste too sweet and you’ll most likely have a stuck fermentation. Each month/week/and as harvest nears, day – the grapes are sampled in the field to see if they have reached their optimum levels yet.
Shipping from Chile to MWG…
Once the grapes arrive at port they are sent to Musto Wine Grape Co. and we unload them into our coolers. Everything is shipped in a refrigerated container and never breaks the cold chain. This ensures that the high quality of the fresh Chilean products are intact. After they arrive it is time for you to pick up your grapes and/or juices and get winemaking!
2023 Chilean Harvest Update:
The Chilean crop looks excellent this season. We are hoping to see the Chilean grapes and juices arrive at around 23-25 Brix, very sweet and juicy. Arrival dates look to be somewhere at the end of April / early May depending on the type of winemaking grape/juice. Give us a call (877-812-1137) or email us at sales@juicegrape.com with any arrival questions.
Fun Fact About Chile: Chile produces more than 1 million tons of grapes every year!
Chilean wine making is a time-honored tradition, and the results are worth it! This will be 18+ years of Musto Wine Grape working with our Chilean vineyards and every year the wines created get better and better. We hope you enjoyed learning about the Chilean wine-making season. It’s an interesting process that requires a lot of work, but in the end, it pays off with delicious wines!
