Formerly known as VQ-15 Yeast

RP15 is a recently isolated Californian strain that was selected from spontaneous Rockpile Syrah fermentations by Vinquiry in collaboration with winemaker Jeff Cohn. RP15 is a moderate rate fermenter with average nitrogen demands. Due to its' ability to develop a structured yet lush and balanced mouthfeel, RP15 is ideally suited to making rich, concentrated reds. Initial winemaker feedback has indicated that RP15 does well with emphasizing varietal flavor and red fruit character. In addition, with careful hydration and nutrients, RP15 delivers good mineral and spice notes to wine. RP15 is recommended for Syrah, Zinfandel, Cabernet Sauvignon and Merlot. Best results from 59 to 90 degrees F, with an alcohol tolerance to 17%.

used with Durrell Syrah
I used RP15 with 2012 vintage Durrell Sonoma Syrah and had a great result. Got a nice even fermentation over 6 days and temperature peaked at 78 degrees, mostly around 74. I ended up with a nice fruit profile. Used Go Ferm Protect and Fermaid K along with it with great success.
