So I'm sitting here with a 24 hour old batch of blackberry melomel and no sign of fermentation (my own fault for pitching my 1116 straight into the must instead of re-hydrating). Previous experience tells me that I need to wait anything up to 4 or 5 days before I start to worry about the lack of fermentation so far, so I'm not complaining about that yet or asking for advice....I am sure it will come good in the end with some warmth and aeration............However, I was just curious to know what is the longest lag time you have ever had with any yeast when making mead? Are some yeast strains particularly known for long (or short) lags?
