A Great Fermenter for a Clean Brew, 22nd Jul 2020

Reviewer: Pete Kurucz

A definite upgrade from the buckets and carboys! No transfers needed at all, until it goes into your bottles.

Very well constructed stand, plastic bottle, and gasket-sealed lid. A few important things to know before using for the first time:
- The butterfly valve and the mason jar should be screwed on hand-tight. The equipment is more resilient than it looks, so don't be afraid to tighten it a more if it is still leaking after filling.
- The kit comes with a relatively small wide-mouth mason jar. Get a larger jar to catch the first round of sediment. Replace the larger jar with the original jar to catch the yeast to save for next time.
- The butterfly valve might not close completely on the first try. I found this out the hard way on my first use. Keep rotating the handle tightly to the close position because it does seal.
- With all that in mind, it would be a good idea to have a large baking pan underneath, in case there are still any small leaks.
