5.0 / 5.013 ReviewsGood for money, sizing is an issueI ordered a #10 solid stopper so I can use my carboy to filtered water from the store to the brewery. #10 was the size recommended by Midwest for use in new Better Bottles. My bottle has been used once, and I wish I had ordered a #10.5. The stopper is a very soft rubber that compresses easily. A 10.5 would make for a snugger fit. I'm afraid to push my #10 hard enough to get a snug fit. It look like it just might pop all the way into the bottle, or at least enough to never come out. All in all, not exactly pleased, but I got what I ordered. I guess it's my fault I ordered the wrong size. I will address the issue with Customer Service and I am confident they will do something awesome. They always do.February 20, 2013For long term agingI age some of my beers for up to a year so I use stoppers to plug up the carboy. I think they let in less air than air locks. Press them in and forget about them till you are ready.June 4, 2013Nice PieceThis is a nice little stopper if you want to use it to plug a carboy or flask.

What I like to use mine for is when you are transporting your carboy to your dark area for it to ferment or if are doing something like changing from a three piece airlock to a blow-off. Definitely handy to have.March 18, 2013easy fix for cleaning and harvesting yeastThis convenient little guy makes cleaning and harvesting yeast a breeze!May 23, 2013Prefer these over the universalPrefer this stopper style over the universal as it is much more sounds and robust with the use of an airlock. Over time, the quality of these will outlaast those that are of the univesal type and seem to hold a better seal overall from carboy to carboy. Can't go wrong with these.June 3, 2013

Browse 2 questions Browse 2 questions and 2 answersThe last 6.5 I ordered is too small for my older 6.5 gallon carboy. Do you have a slightly larger diameter stopper?BEST ANSWER: The next size stopper we currently stock would be the #10 which would be too large for your application. If you plan to use an airlock you might try a carboy cap instead.Will this fit the 5 gallon glass carboy I got from Midwest brewing? Or how about the 1 gallon glass carboys, will these fit those?
