Just got a job at the homebrew shop and I'm about to get my employee discount and replace my 5 gal all grain system with a shiny new 10 gal system. I want PLENTY of kettle room to be able to do extended boils and I get a killer deal on a 25 gal kettle. Might as well match for the mash tun... If I do a 5 gal batch, am I going to be fighting a system this big or do you think it's do able? Hoping to be able to push the occasional 15 gal as well. Thanks!!
