As for your yeast question... lucky for you there's an old ChemE in the house. It's called "temperature control". Circulate the beer/ agitate the tank/ throttle the gas... likely used a combo of all three. Bigger question is HTF do you "cold brew"??? Yeast need warm to do their job... I tried the Gator stuff Tour. Too bitter an aftertaste for me. I liked the cheaper Abita Amber better. I'm giving the rest of the Gator to my IPA loving son in law. BTW here is how Coors does it. https://www.coors.com/process Quote Link to comment Share on other sites More sharing options...

Regarding "cold brew" Tour- had to look up the exact number, but I knew from my home winemaking some yeasts work just fine at lower temperatures, just way more slowly. For lagers you can go as low as 40 degrees, though the range is up to 54 degrees. Don't know about you, but I'm thinking if you sat outside when it was 45 degrees in just a tshirt and shorts, you'd think it was pretty cold.

Fahrenheit of course. 40 Celsius is over 100 degrees F. 40 Kelvin is just a tad colder than liquid nitrogen.... Since we're talking really cold stuff, one thing I regret is never having had the opportunity to play with liquid helium. At around 4 degrees Kelvin, it's only that much above absolute zero, as cold as anything can get in the universe, and it does some pretty wild things. If you poured liquid nitrogen into liquid helium, it would freeze. 2 Quote Link to comment Share on other sites More sharing options...

I'm not an IPA guy (had a good APA once) and I really liked the Gator... but then I was chomping on crawdads at the time... fried and etouffeed. 8 hours ago, Ibleedbrown said: We talking Fahrenheit, Celsius, or Kelvin?

Supposedly that’s the key to cryogenic freezing. Quote Link to comment Share on other sites More sharing options...

Supposedly that’s the key to cryogenic freezing. I had to research it for you, absolute zero can't be obtained- but we've gotten mighty close. Like within 0.0001 of a degree Kelvin. Let's just say, for all practical purposes, we've gotten there. If you're talking cryogenic freezing of bodies for thawing them out in the far future- MHO is it's never going to happen, at least with any technology we currently have. A little personal history. I worked in a Blood Bank reference lab. There's big problems freezing organic stuff for permanent storage. If you remember water expands when it freezes, right? And what's a primary constituent of living cells? Yup, water. We had\have an inventory of super duper rare cells (by comparison AB negative- 1 in 180 persons, is common as dirt compared to a few that were 1 in 50,000- or the only known example in the world type) permanently frozen in liquid nitrogen. Regardless how careful you were in the freezing, when you needed to thaw them out- you always got maybe a little, maybe a lot of those red cells that didn't survive the process. Same thing is happening to those few who thought freezing them will let them be thawed out in the future is the ticket. The few brain cells that survive is all that's going to be left- the rest is going to be some exploded mush. Quote Link to comment Share on other sites More sharing options...
