I'm a new guy learning how to brew. Completed three, 5 gallon extract batches so far. As much as I enjoy the beer, the process of brewing is just as enjoyable. To be able to brew smaller batches, say two gallons, more often, and experimenting with different beers would be great. Will the ingredient quantities be accurate if I resize the recipe down to two gallons. If so, which equipment pot size would you suggest? Thanks.
