Glass Carboy 5 Gallon (23 L)

A classic glass carboy for primary or secondary fermentation. Doesn't scratch like plastic, doesn't permeate oxygen like PET, and lets you watch fermentation directly.

Glass remains our default recommendation for the long-conditioning beers (Belgian dubbels, big stouts, anything that sits more than a fortnight in fermenter). The advantages over plastic and PET:

  • Zero oxygen permeability, which matters more the longer the beer sits
  • Doesn’t scratch, so it can’t harbour microbes in worn grooves
  • You can see what’s happening, which is genuinely useful for diagnosing stuck or slow ferments

Safety note

A 5 gal glass carboy full of wort weighs 25 kg. Always lift from the base; bottom-cradle carriers are worth the money. Never carry by the neck.

Cleaning

PBW or oxiclean-style cleaner, hot water soak, soft brush. See sanitation for the full routine.
