Hi, after brewing an altbier on Sat & pitching Wyeast 2565 (Kolsch), I had no activity after ~36 hrs. To clarify, when I activated the smack pack, it never really inflated so I suspected something was off. However, as I was in a pinch I went ahead & pitched it anyway. The wort was on the cool side when I pitched - probably high 50's but then rose into the low. 60's in the ambient temps in my basement which is right in the suggested range of 55-70. After 24 hrs of no activity, I moved upstairs into the high 60's to try to kickstart but no dice.
Now, as I still had no activity & had no other fresh yeast on hand, I dug through the fridge & came up with an old pack of US-05. It wad a 2009 Best By date on it but I didn't have many options so I pitched last night.
After about 6 hrs now, I have activity - but I am wondering if Im looking at any off effects from using this old yeast? Any thoughts or ideas?
Thanks!
