I have a question that is related to this discussion.What is the temperature gradient inside the fermenter? I think I recall reading that the center of the fermentation vessel is warmer because it is furthest away from the cooling sides. But there are currents in the fermenting beer due to the yeast and the movement of the gases - does this homogenize everything, or is there still some gradient in the fermenting liquid?

I'd think someone with a thermowell and a stick on thermo would be able to answer this...

Where can I find stainless NPT thermowells?

During fermentation the temperature of the liquid is pretty uniform.

Why bother with theory when you can actually measure the temperature with a thermometer?

I bought a few from here, they have good prices and excellent quality: https://cgi.ebay.com...id=p3286.c0.m14They have different lengths and threading at their ebay store.

You have to be careful of some of the stuff you read about brewing. Most of it is in regards to commercial, large-batch brewing. How things work in a 1000 gal conical is not necessarily the same as how they work in a 5 gal carboy.For all intents and purposes, I would consider them equal. Come to think of it, even if they're not, any differences in fermentation character caused by different temps would be combined together in the finished beer. You'd get an average flavor anyway.
