I I'm confused and the more I read on it the worse I get. This is going to be my first true all grain. So be nice! I do lots of medium/ average gravity beers with higher gravity beers every now and then. I'm upgrading to start doing 10 gallon batches. I understand I have an amount of water to mash. And an amount to sparge with to equal 10 gallons of wort, but how much of each? For a 10 gallon batch of average gravity beer. Also what size cooler shall I use for a mashtun? And a brew kettle will a regular size keg work? Thanks for your help!!!!!
