While making my 2nd batch last night from an IPA Dry extract kit the instructions asked for a starter for the dry yeast package which I made and it looked healthy while I was brewing. The instructions said to to pitch around 72-75 degrees but it said to top of the bucket at 5 gallons with 3 gallons of chilled water. I put 3 gallons in the fridge the night before but the thing is, after I cooled my wort down with an ice bath to roughly 95 degrees (the instructions said to get it below 100 degrees) and I added it it in the bucket with the 3 gallons of chilled water, the temp went down to 60 degrees and then I pitched the yeast starter on top of that, put on the airlock and called it a night. I checked the temp this morning when I got up and it's sitting at 68 degrees with no activity yet. Will I have any problems pitching at such a low temp? Also, should I have shaken up the bucket some after pitching? The instructions didn't say to so I didn't. Would you recommend shaking it up now? Thanks!
