That’s right and it’s actually at the lower end of my preferred temperature range for cask ale.14° is pretty impressive, it's only a degree or two over ideal cask ale serving temp.
Inspired by your test, I thought I would measure my set up to see how it compared. Following advice from an earlier thread, I have got my King Keg in a tray filled with water. I've draped a towel over the whole keg with both ends in the water, and I've set a little usb fan on it to give it some welly. I then put another king keg next to it in the tray but this one is filled with water, has no towel on it and also no lid, so is pretty much ambient apart from the cooling effect on the bottom inch where it's in the water.A day later and...
The ambient temperature this morning was 17C, the beer temperature was14C. The ambient temperature has risen through the day to 20.6C, the beer temperature is still 14C.
Now it’s getting a little bit more exciting!
Great review. Looks pretty useful, though it won't work for me as my King Kegs have their tap at the bottomHere a review of it
I've never had any fermetation control as I don't have room for either a brewfridge or fermentation chamber so when I saw the fermentation bag I thought it would be the perfect solution for me. So after reading all the positive reviews on Amazon and morebeer I decided to buy one from...www.thehomebrewforum.co.uk
Here in sunny Suffolk at 6 p.m. yesterday evening I hadToday’s report...
Ambient temperature is 23.6C
Beer temp is 15C
Now that’s more like it!
I’ve been thinking about this because it’s a great idea. My thinking is that a waterproof bag containing something could be taped on the inside of the pocket and in direct contact with the keg. The “something” could be water but this will just pool at the bottom of the bag so it needs a little structure - either more of a gel or many cells like an ice cube bag.In the pockets for the ice blocks it would be good to have something that'll thermally bind the blocks to the barrel - like bags of gel or water.
10.5 degrees reduction is very impressive and English style beers as I discovered yesterday taste great at 16Here we go...
Ambient temperature is 27C
Beer temperature is 16.5C
I’m calling that a win.
That’s not bad. I’m assuming you use chilled water but if not you could try keeping water in the fridge/freezer in an old coke bottle or similar and replace/replenish the water in your tray with ice cold water.10.5 degrees reduction is very impressive and English style beers as I discovered yesterday taste great at 16
My figures for yesterday are not as good, though not hopeless
Air temp 29.8
Water, in keg just sitting on the counter, a surprisingly low 24.4
Beer, in keg in tray of water with towel draped over and two fans, 20.4
While I'm happy with the reduction of 9.4 when comparing the beer with ambient, the beer was just too warm to be enjoyable whereas I think 16 would have suited my present brew perfectly.
Whatever the method I shall be glad when it's cooled down a bit.................
No it was just water straight out of the tap (rising main, not roof tank). I probably could improve it as you say by using chilled water, but I'm trying to keep it as simple as possible without trespassing on fridge/freezer space if possible!That’s not bad.
