Big Mouth Bubbler 6.5 Gal Plastic Siphonless Fermenter with Harness
Haven’t opened it yet but it shipped quickly and arrived intact and in time.
I decided to use my new BMB today as a primary fermenter. I've read so much about the lid being a problem. After sanitizing it in Star San the lid doesn't seat as well as it does when dry which is understandable. Star San is very slippery! Once dry it will be fine. I think the harness is great! Makes moving 5 gallons easier. Next time a decent sale comes around I'd gladly get another one.
I use the big mouth bubbler for secondary fermentation and have found it makes racking simpler and more efficient. After using one bubbler for my 2019 batch, I immediately ordered a second to rack from one to the other as many times as required; next year. Very pleased with the product.
Lightweight with a nice harness that fits any big mouth bubbler also very easy to dry hop because of the big mouth!
