I used this recipe: 19 lbs honey, 4.5 gals water, 1.5 packets Lavlin EC-1116 yeast, 5 tsp Fermax nutrient, to arrive at 6 gals of must at a CG of 1.115. Last year this recipe started percolating within hours. It's 12 hours and there's some foam but no gases yet. What is the average time to get the fermentation going?
