To anyone who uses an immersion chiller

[magno]

Super blast from the past! Looks like I used to cover with aluminum foil... I also recall using the lid to cover as much of the top as it could without a notch cut out... but I've been using a plate chiller for several years now (with the lid on).

I use a piece of foil insulation with notch cut. I had a roll I used to wrap around my keggle when I did BIAB

Depends on whether I am brewing on the back deck outside or if I'm in the garage. Typically, I have the lid on, not notched, until i give the IC a good swirl to promote the whirlpool action to chill down faster. Even with my home built 20" 3/8" copper IC, I can chill down to 70F in about 45 minutes, with the lid on

I have my Spike Kettle lid notched.

My BrewBuilt kettle came with a notched lid. I put that on and wrap a starsan soaked rag around it to completely plug the opening. I worry less about it in the winter, but it's just part of my process now.

I used to brew in the driveway, now I brew in the garage.
