I use these to make mead in. I wish they would have gallon marks on the fermonster. I just ended up adding my own.

Light weight and easy to clean need I say more!!!

Always great stuff. Very quick turnaround as well.

Sometimes when your grape harvest is off a bit, you need something smaller than the typical 5, 6, or 7 gallon size carboy. The Fermonster 3 gallon sized is just about perfect when that happens. Just as for the others in the Fermonster line it is easy to clean, easy to sanitize, easy to fill and if you install the o-ring correctly, is air tight over the long term.

Used this 3 gallon carboy to ferment a 2.5 gallon test batch. The plastic made it very lightweight and easy to handle. I’ve heard some concerns about the o-ring in the lid but there are several YouTube videos that explain how to put in in so it wasn’t a problem. Cleanup was really easy since you can put your whole hand in it. It could be improved if #10 bungs with holes suitable for pressure transfer were available,

It's a great fermenter, plastic a bit soft.. sorta feels like a soda bottle... I do recommend to get the lid wrench with it. Cause it gets stuck. Basically it seals perfect just need help to open the lid.

Just completed my first ferment in this thing. Worked great! Large opening means I can pour in lots of grape bits and even drop (and later retrieve) some big chunks of oak.Only one issue (which isn't big enough for me to give it fewer stars): wall thickness. It's super-thin so if you move the fermenter, just be prepared for the airlock to bubble out some liquid, or suck some back in once you set it down.

Worked great did a elderberry wine. Do get the lid opener.

Great for small batches, test batches or if you are just getting started. Easy to clean & dry hop plus its harder to break than glass. Top does take a large than average plug (#10 is needed)

Great upgrade from a 1 gallon carbon. Easy to use and prep. Have a gallon brewing now, hopefully easy to clean as well as prep for brewing

Picked up two of these 3-gallon fermonster plastic carboys. The wide-mouth opening is great for cleaning -- easy to reach in and scrub down with a soft cloth. Also, very few internal ridges for grime to hide. The lids really solid and easy to remove. Wish the bung hole was a standard size. Feels unnecessarily large, and requires #10 stopper which never feels quite tight to the lid. The thin o-ring that seals the lid to the carboy is also very finicky. I had a lot of trouble getting it to fit in the tiny groove in the lid. Very difficult to remove for proper cleaning.

Easy to clean. Light weight.

Liking all my fermonsters so far, and the 3 gal is a convenient size.

Bought this so I can do small batches of fruit wine. The only thing I didn't like was how thin the walls are.

Pitched the yeast and never any bubbles in the airlock. But there was a thick Krause which indicates it was fermenting. Finished, bottled, and then put water in the fermonster and it leaked. Retightened several times and couldn’t get it to stop. Not leaking in the gasket but rather around the lid to airlock area. Called morebeer and they said make sure totally dry and try agin so I did to no avail. Called again asking if they had any other #10 stoppers other than the one they originally recommended. Morebeer recommended the universal stopper #10 with hole cost a little more 3.60. This was the answer and I am quite pleased since this is light, a good size for experimental batches, and love the wide mouth. Thank you morebeer.

This fermenter works very well for primary fermentation of 3 gallon batches. The large neck opening enables easy cleanup. The one shortcoming of this vessel is that the wall thickness is thin compared to the 3 gallon narrow neck vessels and the 7 gallon Fermonster from the same manufacturer. Had I known in advance these were manufactured with thinner walls, i would have stayed with the narrow neck version. If the manufacturer made with thicker walls it would be a five star product

Price is great, and I needed this size. Downsides are walls are a bit thin/weak, and o-ring in lid can be quite difficult to sit in groove properly.

I’m 76 . I’ve been growing cold hearty grapes for wine since I was for 40 years . Blending varieties is a truly learning experience. Make3 gallons of wine from one variety not only teaches you the true characteristics of that grape ( Should one use it as a wine by itself or what would it add to a blend . ) . The small experimental vintner like I am does have the options of a professional business. They would think my 1 .5 acres of grapes a joke . I find this carboy a blessing. When you are my age lifting glass is tough. This is truly helpful . Wish my small finances aloud me to purchase more . One takes one year at a time .

I like these Fermonsters because I can get my hand inside to clean it. Ordering and delivery from MoreBeer were quick and easy. I have a couple 5-gal Fermonsters that I used to make hard cider. This time I bought a couple 3-gal (and a 1-gal one) to make mead. The only down side, if you want to call it that, is it takes a lot of honey to make a 3-gal batch of mead. But my bees have been busy, the yeast is now busy in the Fermonsters, and soon I will be busy sipping the results.

This is a great size for doing batches of wine and mead. The wide mouth makes dealing with fruit in bags easy. Using all the different size Fermonster carboys are great way to brew and make wine. Lighter, safer, easy to clean and cost less than glass. The lids are interchangeable between carboy sizes too.
