11 Litre Glass Carboy

Glass Carboy — 11 Litre

The 11 litre glass carboy hits the sweet spot between a 4.5L demijohn and a full 23L carboy. It's ideal for brewers who want to scale up from single-gallon batches without committing to a full 23-litre ferment — producing roughly 15 bottles per batch.

Italian-made with straight sides for easy cleaning and a classic look, it works equally well as a primary fermenter for beer or cider (with a blow-off hose) or as a secondary vessel for wine aging.

Why Choose the 11L?

• Perfect middle ground — more than a demijohn, less commitment than a full 23L batch
• Airtight glass — impervious to oxygen that can harm your homebrew
• Easy to sanitise, odour-free, and scratch-resistant with careful cleaning
• Popular for split batches, experimental brews, and bulk wine aging

Specifications

• Diameter: 23cm
• Maximum height: 43cm

Important Notes

• There is a small casting line at the base on the outside — normal and does not affect performance
• Do not subject to extreme or rapid temperature changes
• The neck is slightly wider than a standard demijohn — standard demijohn bungs will not fit. See our Rubber Airlock Holder Bung (Large) for a suitable option (check sizing before ordering)
