We need to have a beer together!
For me Rock Bottom is no 1 and always has been...and Hackett has done way better stuff than Supper's Ready - Spectral Mornings? Every Day?
A week or two is fine normally, I have due to laziness left mine for longer - in theory, it's all still sterile....but the longer you leave it the greater the risk...get it packaged now I would say.
From memory, I think there's 2 packs - one goes in at start of fermentation, and the other goes in about 3-5 days before kegging. I think they provide hop socks to keep it all together too. Good kits.
Does anyone know why it isn't Government policy to put Solar Panels on all new builds? Surely for a new estate you could set up localised collection and distribution etc ? Just a thought...
