My traditional Mead is coming along nicely, and is currently in Secondary. It is about three weeks old, and I racked it to secondary because the airlock has slowed down considerably. (once every minute or so) I have it sitting on my kitchen counter, wrapped in a blanket, so that I may watch the progress. It has dropped almost as much yeast as primary fermentation did and it's only been in secondary for about 5-6 days. The yeasts stated alcohol tolerance is 14% but it has reached 15%, though it is still fermenting slightly. I'm going to be adding some additional honey to sweeten in the next few days. (2.5 - 3 lbs.) Would it be a good idea to add a tiny bit of nutrient to "help out" the suspended yeast, or at this point would the yeast not have enough time to consume the nutrient, due to high abv content, and leave an off flavor?
Also, I'm going to mix in a little sulfite to keep the mead from grabbing too much air during the mixing processes and oxidize. Would that shock, or possibly kill, the yeast?
Thanks for any help,
