NN had the lowest TH and the cleanest taste among the four "premium" nics we ran a blind taste test on last summer. The test was largely motivated by me second-guessing what I was putting in my freezer. I understand that some people like a lot of TH and would find fresh NN or VT premium to be lacking in that respect. But I'm not in that camp, and especially for the purpose of a vapocalypse stash, my theory is to put the cleanest nic possible in the freezer, 'cause it's unlikely to get any better with age.
