Product details

Enoferm RP15™ was isolated and selected from spontaneous Rockpile Syrah fermentations. This California isolate is used in concentrated reds, particularly Syrah, Zinfandel, Cabernet sauvignon and Merlot where a moderate fermentation rate is desired for rich, lush, balanced mouthfeel and full bodied wines. RP15™ has a moderate nitrogen demand, and will allow good results with varietal flavor, and red fruit and mineral aromatic note development, when carefully rehydrated using GOFERM STEROL FLASH™ before inoculation into musts.

Selected by Isolated from Rockpile Syrah fermentation, California, USA
