It's been 2 1/2 days since I pitched Wyeast 2000 Budvar Lager yeast into my CAP and there is still no airlock activity. I pitched at around 9.5 (celsius) and let it cool to and held steady at 9. I've given the fermenter a good shake a couple times a day to no avail. I'm now letting it warm up a couple degrees to see what happens. The smack-pack was slow to act, but there was activity. Any thoughts? Be patient? Pitch a pack of SA-05 for a light corn ale?
