I brewed a high gravity 1.092, 90 minute ipa everything on brew day went better than planned. I used a 600 ml. Starter with an English ale yeast that came with that kit from the lhbs. I aerated the wort after I cooled it for approximate 24 hours. When I pitched the starter I had great airlock activity about 3 hours later. Then with the unexpected autumn weather the house heated up to about 88 degrees I couldn't even read the temp on the thermometer attached to the bucket so I threw the bucket in the keezer for a little bit to try and bring the little yeasties back while the temp in the house came down as soon as the thermometer hit 68 I pulled the bucket. It has almost been 24 hours now and I have very little activity with a high gravity beer like this I was expecting activity in the bubbler for at least a 7-10 days. What can I do to ensure this ferments and finishes properly
