I intended on brewing tonight so I broke the activator on my Wyeast 1450 last night. Only today did I realize I'm missing a fermenting bucket to actually ferment with (d'oh, big mistake!), so I'll have to wait until tomorrow when the local homebrew shop opens to pick up another.
The Wyeast pack is completely swelled and I'm worried that my yeast will begin to die off before it's even grown. Will it still be good tomorrow? How long between activating the Wyeast pack do I have to use it?
