I've had some brews take 2~3 days to start bubbling, depending on the temperature, yeast, and whether or not I did a starter. Don't panic yet.I used some Thames Valley in my Winter Spice ale but after 36 hours I'm not seeing any activity. Has me nervous the Wyeast pack may not have been enough.
Yeah I'm not freaked yet but I had an ESB yeast I got cheap cause the smack pack was broken that didn't do anything in my starter for 2 days so I tossed it and went with the Thames. Just going to be annoyed. I have some nice IPA yeast I harvested myself I could use in a pinch but it's not really what I'm going for.
