15 Gallon Glass Demi-John


Product Number: 7036

Availability: In stock

For the serious brewer or winemaker. Big enough for large batches. The 15 Gallon (56 liter) glass Demi-John uses a size #11 rubber stopper or a Large Universal Stopper . Comes complete with carrying basket as pictured. Do not pick up the demi-john using the basket when full.

Caution: This fermentor is a large hand-formed glass item that can be easily damaged if not used with proper care and handling. It may have variations in shape and thickness, and will show the normal bubbling characteristics of hand-formed glass. Extreme changes in temperature or sudden contact with hard surfaces may cause glass to crack. Handle with care. Do not pick up the demi-john using the basket when full.

Saves a fortune over a conical Review by Dan

Product Rating:

i age Barley wine for a year in my Demijon. I ferment in buckets and after a couple of weeks move it to my Demijon where I seal it up tight with a bung. Cleaning is not as hard as you would think. I use a jet washer and carboy cleaner, then top it off with a long full strength PBW soak using the same solution that I used on my equipment, so there is no waste.

Well suited for making Lambics Review by Bolars

Product Rating:

It's air tight unlike a barrel so you wont have an Acetobacter infection ruining your Lambic. I can let in the amount of air that I want. I've had it in use for over a year now. It's much less expensive than a large stainless steel conical and I plan on getting another. Cleaning is easier than you think. Use a jet washer, then a long PBW soak at different angles. You don't need to make 15 gallons of PBW. Then I use that mix on my other equipment.

hard to clean Review by Macpatches

I love this Demi, 1st one arrived broken but had a replacement 3 days later. The only issue I have is, I can't find a bottle brush long enough to clean it properly.

A great big carboy Review by William

This is actually one of the best pieces of equipment I own. I cleaned it thoroughly when I got it and have used it continuously. I make Lambics that I age for 2 years. What I do is make 5 gallons, age it in a carboy for a year, brew another and start aging it. Then I take 5 gallons out of the Demijon, and add in the "young" Lambic. I have a pipeline going.

By the way - don't even then about moving it when full.

glass carboy Review by chris

This works okay for a big batch, alcohol content was a little on the low end but that's likely because of the temperature of the glass and not because of the bottle.

As enjoyable to watch as to sample.

Great for wine making Review by CorgiCode

(Posted on 1/5/13)

Product Rating:

I've had a pair of these for a few years now. They are fabulous for wine making, as an alternative to more expensive stainless steel bulk aging tanks. I make 30 gallon batches, so two of these are just right to rack into for additional aging after the wine has done its time in oak. Obviously, they are too heavy to handle when full, and there's always a chance one will break, leaving me a sorry SOB with an ankle-deep flood. Fingers crossed! Untli then, I'm liking them a lot.

For big batches Review by Phoebe

First - while the basket is cheap and not very nice to look at - it's job is to protect the fermentation chamber from light. It does the job.
Second - the glass is strong and up to the task. It's heavy so you wont be moving it. Thats understood. Your only alternative is to get a bunch of 6 gallon Better bottles, which might not be a bad idea.
Overall, this Demi-John is ok.

Ok Review by DaveD

I got this a Christmas present and I am still happy with it but there are a few things. I did get to see the packaging and it was good. It arrived safe and sound. Upon further inspection, the glass looks like it has a whole lot of air bubbles in it which makes me doubly cautious. The other thing is it was dirty. I mean really dirty. Seriously folks you need to make a good impression on your customers and a little cleaning before shipping will go a long way. I am still cleaning this thing.

This bottle was sent to me covered with cobwebs and green mold.The so called basket is made of plastic,it smelled like a wet dog.It took one hour to clean with hot water and bleach.When i called to inform Midwest about the bottle they asked me to send pictures.After sending the pictures i recieved a text from them telling me this is not how they do business and i wouled get a call from them the next day.This never happened until i texted them 5days later.I was told they were going to send me bonus points for future product.I will not be ordering from them again.
