Hi All again. It's my first full autumn in this mead making game, and I've been busy 'hedgerowing' picking up a few kilos of blackberries. As they're quite soft fruit anyhow, is it advisable to put them thru a freeze thaw cycle for maximum juice and flavour extraction, or is that pointless and risks changing the flavour? I'll be using trying them out both in primary to some new batches, and also as an addition to a fairly strong (18-19%) but bland base mead.
