I have done a couple 1 gal batches and am moving on to 5 gal. Is there any difference as far as process goes or is about the same? I do all grain.
The process should be the same. Course different aspects will require new and better methods. Chilling comes to mind. But what we do all grain, for 1, 5, 10 or 20 gallons, is essentially what the pros do. Brew on!!
Yep, chilling and being able to handle a larger boil with your burner/stove are probably the biggest things to consider.
Agree with the above on chilling. I would extend that to temperature control through the fermentation process.
The more volume you are handling the more issues arise relating to how to handle that volume.
