Wines I'm Making: Fermentation (September 29, 2014)

I inoculated our pressed Cabernet grapes yesterday, after a four-day cold soak. We picked the grapes on the 24th. This morning, the wine is beginning to bubble a little. The fermentation appears to have begun. The Sangiovese rosé fermentation is now in day four. Having had minor problems with hydrogen sulphide in the past two years I decided to use the yeast nutrients usually recommended (DAP and Fermaid K), although I've never used them in the past. I'm hoping better nutrient availability will prevent hydrogen sulphide problems this year. We'll see.
