I've only ever brewed 5 gallon all grain batches, but I would like to try to scale up to 10 gallons soon. I plan to do so by just using Beersmith to scale an existing 5 gallon recipe. I would like to know if there are any 'gotchas', in the transition. My brew kettle is a 1/2 barrel sankey keg, so boil overs shouldn't be an issue. My mash tun is a 70qt rectangular Coleman cooler with a copper manifold. I haven't had any issues with stuck mashes for 5 gallon batches. I plan to ferment in 2 separate 5 gallon buckets or carboys. Additionally, should I always use rice hulls for a 10 gallon batch? Thanks!
