First posted question here so sorry if I've missed a previous answer. I've been trying out a secondary ferment in old champagne bottles of a barrel fermented cider. When decanting into the bottles I have been careful to exclude all sediment from the first ferment and the brew is nice and clear. To start things going again I've used either apple juice or sugar. I'm very happy with the carbonation, but the fermentation is leaving dead yeast as a sediment which clouds up the cider once opened. I was thinking that a way around this might be to use carbonation drops to get the fizz hence no sediment. What's the quality of the bubbles like in terms of size and how do they last in the glass if using drops? Thank you.
