You can use Mason jars to store hops, grain, yeast slurry and more. Fermentation lids are also available to convert these to be easily used for yeast starters. And, of course, you can serve your beer and other drinks in a one of these. Mason jars generally economical, reusable, oxygen impermeable and you can easily see the contents.

Jar Sizes

A variety of manufacturers make Mason Jars. Ball, Knorr and more. There are two standard sizes regular and wide mouth. This is important when it comes to attachments and lids as these must be size compatible.

Sealing Hops in Mason Jars

FoodSaver makes a jar sealing attachment that connects to compatible vacuum sealers to allow you to vacuum seal Mason Jars.  This means $0 in vacuum bag costs and the jars are resealable with no vacuum bag waste.

Note that a compatible vacuum sealer and jar sealing attachment are requirements. Many FoodSaver brand vacuum sealers have accessory ports.  The Inkbird VS-01 pictured here also has an accessory port.

Grain Storage Capacity for Larger Mason Jars

Using my rule of thumb 1.25 lbs per liter, the half gallon size jars should hold around 2.36 lbs of grain and the quart jars should hold around 1.17 lbs of grain. These are rough estimates.

Using Mason Jars for Yeast Starters

Lids are available to easily convert these jars to use for yeast starters. As will all other options you need the right size lid (either regular or wide mouth).

A tip… fermentation weights are also available, those are generally intended for fermenting food. The sit on top of the food and are not airtight. Along those lines they should be avoided if you’re wanting to do yeast starters.
