Viva la Revolution! Hand in hand, carbohydrate and yeast came together in forbidden unity. The carbs didn't suspect the yeast's eerie intentions and accepted an invitation to dinner. By the time they discovered they were the main course, it was already to late. Feral yeasts turned cannibal consuming and reproducing at a rapid uncontrolled rate. Major mistake #1. I didn't introduce them. Being the large wine Petite Sirah is intended to be, I preferred a pre-fermentation cold soak to ensure full flavor and deep color. After 5 days in my garage, the fruit temperature began increasing despite the blanket of dry ice so I transported the fruit to a friend's temperature controlled tasting room. I punched down lightly twice a day and closely followed the Brix. 22.5 at harvest increased to 25 after sitting on the skins, which I was happy with. I wanted to innoculate the evening of the 18th. 8 days of pre-fermentation maceration. Using a standard floating hydrometer (sugar tester), I discovered a 5 degree drop in sugar. Feral yeasts, like wild dogs, run rampant and cannot be controlled without immediate attention. Of course, it was late evening, brew store closed, and I did not have designer yeast. Major mistake #2. I didn't have the supplies to control the situation. Hoping to slow the rascals down, I added dry ice to create a less then hospitable environment but by the morning the Brix had dropped to 10!!! A very gracious winemaker took pity on me and provided yeast RP15 which I immediately "pitched" (yeast addition) with an activator. Sometimes, with quick action, the winemaker's deputized yeasts will corral the outlaws and take back the town. The next morning I was at 3 Brix and by the end of the day was dry (no more sugar). I'm not sure who won the wild west but Bacchus was feeling merciful and granted justice and rehabilitation. No off odors and the wine had potential to develop into something beautiful. That's fantastic but at the time I was just glad it was wine. Lesson: Control your temperature if you intend to cold soak. Environments change and things happen very fast.
