I recently purchased 6 gallons of ice wine juice from a local grower in upstate NY. The Brix was off the chart on my hydrometer. I'm guessing 50+? I added the obligatory crushed campden tablet to the juice and let set a day before pitching EC1118 yeast. I also added yeast nutrient and energizer per recommended doses. It has been nearly 3 weeks and I have not had any fermentation start. After a week or so, I pitched another packet of 1118 to try and kick start a ferment. Still nothing. My basement is about 65°. I drew off about a quart of must and brought it to a warm room in the house and hit it with another dose of nutrient and energizer. Still nothing..... What should I do next? I've got about $100 tied up in this juice. I'd hate to have to dump it.
