Honestly, just make some while you are building, mining or exploring and fighting. That way you can get around just waiting for it. Cause yea, waiting for it can be boring but luckily you can always get around that by keeping busy.

Additionally, what other people said also, you can make multiple fermenters and get more for the same amount of time, so all in all its fairly balanced. Especially considering the health potions while you are on high food.
