Quick background...back in December I bought a Northern Brewer Scottish 70
kit with a Wyeast 1728 smack pack. I kept the yeast in the fridge in my garage and in late December, early January the outside temperature dropped to the teens for a couple weeks. I was worried that the temperature in the fridge may have dropped too low and that the yeast may have been damaged so I went out to my LHBS
and bought another yeast pack to use. I smacked both; the older one didn't swell so I only pitched the new one. Well now 18 hours later the old one has swelled. I'm not going to make another scotch/scottish ale in the next week so should I pop open my fermenter and pitch the second pack? Otherwise it's going in the trash...
On another note it's been 18 hours and I'm not seeing much activity, though I think it's a bit cold as the temperature stripe on the bucket says it's 60 degrees, so I'm trying to raise the temp a bit. Any thoughts?
