Demi-Johns & Carboys
The difference between a Demi-John and a Carboy is size. Carboys are much bigger and hold more liquid than Demi-Johns.
Demi Johns and Carboys are designed as a secondary fermentation vessel.
The initial fermentation should be completed in a larger vessel such as a brewing bucket. This is because the initial fermentation is very vigorous and gives off a lot of carbon dioxide. The carbon dioxide helps prevent infection, but this can cause a large amount of foam on top of the fermenting liquid. If the initial fermentation is performed in a demi-john or a carboy, you risk the airlock becoming blocked by the foam, when can then lead to the possibility of an explosive eruption and a lot of cleaning up.
Once the initial fermentation slows, less carbon dioxide is given off. This means there is more chance of infection. This is the time to syphon your fermentation into a vessel with a smaller neck with an airlock such as a demi-john or a carboy.
The Demi-John or Carboy allows you to ferment wines over a long period and helps prevent infection from airborne bacteria.
Demi-Johns and Carboys are not designed to hold a carbonated liquid, so a solid bung for long term bulk ageing should only be fitted if you are sure the fermentation has completed. For security, a safety cork or airlock should be fitted.

You will have the fermenter foaming all over the floor and walls but you will have the real quality that you want .
Made fruit wines of all types for years and on some as a hobby , had a go last year base level wine kit and so so ,a bit sweet ok if you only want to get well oiled . But this added to a kit is wow for a nearly sixty year old wine drinker just try adding half the bottle to your next 30 bottle kit you will never go back.
Very good works a treat.makes the wine look professional and attractive to the coinesseur.
I made my first ever wine, blackberry wine using this bag after following David on his Youtube video, great product, less mess and easy to use. Thank you David for your help and support with my order.
Easy kit to brew. Pleasant, very refreshing apple flavour ideal for lazy summer days in the sun. Very impressed and intend to try others in this range.👍
Excellent product , delivered safely and promptly
My second time of ordering. Over Christmas, brewbitz were also extremely helpful when I had a change of shipping address.
Really top rate product. The neck hole is the correct size for rubber bungs, Nylon fermentation bungs & Safety Bungs, unlike that which others are selling.
I had run out of camden tablets, the fresh supply halted any residual fermentation prior to bottling, Banana Wine clears without any intervention,I reccomend it.
A really good bit of kit, saves a lot of time & hassle filling your bottles. Once you do a few adjustments your good to go. It is also well made. All in all a really good addition to your brewing set up
Great tasting wine with easy to follow instructions
Brilliant, absolutely brilliant can’t fault there website , delivery service, 5 stars 🌟 🌟🌟🌟🌟
I looked everywhere for this size washer to fit the taps on my fermentor - delivered fast and as described :-)
the family love it, getting more visits than usual.lol
Needed to boost my white wine stock so I tried this kit. Easy to make but did take a couple of days longer to complete fermentation than specified. Having said that, it's December and the fermentation room is cool. Whilst I used a heater pad with temperature control, I think the fermentation conditions were not perfect. Hence the extra day or two. The bulk of the brew is waiting polishing but I did run a sample through a gravity filter for tasting. Very pleased with the result even though it has had no time to mature :-)
A very good kit supplied by a very reliable supplier
, it's a great favourite of all of my friends when we have a get together.
