This has probably been discussed a million times :-[ but … ;D
In looking into all grain I’m looking for a cooler to do batch sparging (a la Denny).
Right now it looks like my options would be between a Coleman Xtreme or an Igloo Marine (both rectangular) and was wondering if there are any issues with one or the other (for me the Igloo would be cheaper).
I’m also wondering about the size. If I plan on doing 5 gallon batches, maybe even some “big beers” (high gravity) in the future, what would be good a good size to look at, so that I’m not kicking myself for either having too much head space to not be able to easily keep a steady temp, but to not worry about having too small a size to deal with bigger grain bills.
I use a redigloo 52 qt cooler, and it makes beer every bit as good as those blue ones… Seriously though, I can make session beers and high gravity beers with the same cooler, all for 5 gallon batches.
+1, I just made a 1.033 with 7 lb of grain with normal 1-2* loss and I have maxed it out with ~30 lbs at 2qt/lb for a 1.105/1.032 partigyle. it’s a 72 at extreme. (blue)
I don’t think either of the models you mention will make a difference. Look for the one with the lowest drain that will drain the most completely. 70 qt. is a good size. I have a 48 qt. which maxes pout at 10 gal. of 1.050 beer or 5 gal. of 1.100. And even that is hard to manage.
I use the 82 qt Coleman Extreme for 10 gallon batches. It works well but I do find that, with thinner mashes or step infusions, it is easy to fill it to the brim, especially on the high gravity brews (>1.080). I’d recommend the 100 qt (or higher) coleman cooler for higher gravity brews if you’re doing 10 gallon batches.
