Vintner's Harvest CL23

$3.00

Saccharomyces Bayanus – Ideal for crisp, fresh dry white/blush and all sparkling wines. Also the best strain for high alcohol tolerance.

CL23 produces very low levels of fusel oils and other congener compounds during fermentation and so does not contribute much to wine flavour or aroma and can therefore be considered to be a particularly neutral / clean fermenter. However CL23 does contribute significantly to the wines structure and ferments out sugars completely allowing for the driest of wines to be made.

CL23 is noted for its robustness, being able to ferment to 18% abv. ethanol, tolerate high free SO² and high levels of other stress factors such as organic acids, incorrect temperature and pH making CL23 the strain of choice for high alcohol wines or where uncertain recipes are employed and fermenation reliability is a key factor, or where low temperature fermenation, down to 46° F, is required.  This strain is very fermentation friendly in that it produces no foam, starts fermentation quickly, therefore avoiding potential infections, and can be used to re-start stuck fermentations.

CL23 can be used for red winemaking, especially if good structure and dryness are needed, but it will take out color and fruit flavor.  This is the Vintner's Harvest version of the Champagne Strain.
