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.
