I had 2 packs of this yeast to make a starter with for my bock. When I opened the packages they smelled pretty bad. Is this normal? I went ahead and used a cup of DME with 1300ml of water and boiled that for 15 min. It's been 8 hours now and there's no activity in the starter flask. When I smacked the pack and let it sit for a while they both started to balloon up so I think they were good. How much longer should I wait? I've read this one is slow.
