Just finished a all grain batch of Vienna Lager. Smacked the Wyeast #2633 last night, but hardly any swelling of package. Made a yeast starter first thing this morning which sat for 6 hours before dumping in the fermenter. Still no real sign of any activity. Called Home Brew Supply where I got it and they told me to let them know if nothing visible after 48 hours. Just wondering if anyone else has had a similar experience with this yeast?
