I am making an old Ale for Christmas.
5 g batch. Primary 1 week. Secondary 3 weeks maybe 1 more (Lazy…).
Using Lallemands/Danstar Nottingham dry yeast: 1 package.
I have never used this yeast so I don’t know if it is still living or not. Should I dump in another package when I rack it?
Most likely there will be plenty of yeast left in the beer to carbonate the bottles. I would consider repitching if the ABV is high (~8%+) or if it spends more than a month in the secondary. If you do decide to pitch yeast at bottling, you can rehydrate a packet and put some of the liquified yeast in the bottling bucket - there’s no need to add all of it since a whole packet is overkill.
Sometimes I will fold the yeast pack and put a small piece of tape on it to keep it closed. Then I will put it into a small ziplock bag and put it in the fridge till next time. This may not be ideal but it seems to work.
I keep a pack of t-58 in a bag in the fridge and it seems to keep on working fine. I just sprinkle it in as the beer racks not bothering to rehydrate. My wife has a container of bread yeast that been in the fringe for over year and the bread still rises.
