I am new to mead making and decided to buy a 1 gallon mead kit from a local brew supply store. The instructions stated to add a crushed Campden tablet to the must 24 hours before pitching the yeast. Beersmith (I brew beer regularly) stated that I should only add 1.5 grams of lalvin 71b to ferment the mead and to use a staggered nutrient schedule. I added the 24 hour nutrient addition and am on 48 hours after pitching the yeast and am still not seeing any activity in the airlock. Did I mess up by following the kit instructions and adding the Campden tablet? Is my mead a lost cause? Thanks for your advice.
