Looking to purchase an assembled Rubbermaid cooler mash tun. My plan is to make 5 gallon batches. Is a 5 gallon cooler big enough? Or do I need to get the 10 gallon one?
What do you guys consider big beers? I really don't ever expect to go up to 10 gallon batches........that is a lot of beer! I personally hope to do lots of smaller batches so I can try new recipes. I don't want to make batches bigger than I can drink fairly quickly. I would hate to be dumping beer thst went stale.
Edit: My brew pot is only 10 gallons..........
One thing to look at is that the less dead space there is, the less temperature loss you will have. I filled my 10 gallon lid with foam sealant, cover with a sleeping bag, etc. and still lose around 3-4 degrees in a 60 minute mash. I have not yet tried covering the mash water with a pizza pan or similar device to reduce the effect of the dead space, but that's next. I actually have both the 5 and 10 coolers but have not yet modified the 5 gallon version. I plan on doing it for my 5 gallon batches so that dead space will be reduced.
Do you preheat it?
Try putting foil on top of the grain bed...or stop brewing outside in -10° weather!
