How to keep track of home-canned food

Updated October 17, 2026

If you’re wondering how to keep track of canned food you made yourself, start with the product and processed date on each jar. Keep a matching canning inventory entry with the jar size, remaining count and location, and update it when you take jars or move them.

Finding a jar of green beans is one thing. Knowing which batch it’s from, how many more you have, and whether the rest are downstairs takes a little more information.

You can keep that information in a notebook, spreadsheet, or app. The useful connection is between what’s on the label and what’s in your canning inventory. Your cantry is the whole collection of home-canned jars, wherever you store them; the inventory is its record.

Match the labels to the record

Write the product and processed date on the jar’s lid or label, and use those same details in the inventory. A consistent product name makes it easier to find all your batches together.

For each batch, include the jar size, number remaining and jar location. If part of a batch goes in the kitchen pantry and the rest downstairs, keep a separate count for each place. Do the same for different jar sizes.

“Basement” may be enough if there’s only one shelf of jars there. With several shelves, “Basement, shelf A” will save you some searching. Recording where your jars are stored has examples of names you can use.

When you move jars, update the location and the counts for both places. Otherwise, a search can send you to a shelf you cleared weeks ago.

Finding older batches

Sort the inventory by processed date, oldest first. In this example, the green beans from July 12, 2025 appear before the batch from August 2, 2026, even though both are pints on the same shelf.

The date on the jar helps you pick the matching entry when you take it. If you take a jar from the newer batch, update that batch’s count rather than subtracting from the older one.

Sorting tells you the order of the recorded dates. For questions about the food or its storage, refer to a tested source such as the National Center for Home Food Preservation.

Updating the count as you use jars

Opening a jar for dinner reduces what’s on hand, and so does giving a few jars to a friend. Record those changes in the place you’re most likely to keep up with: a tally on a printed sheet, a number in a spreadsheet, or an entry on your phone.

Keep the sheet and pencil beside the jars if you’re using paper. If several people take jars, make sure they know where the record is and how to update it.

Subtract discarded jars too. You can note gifts and discarded jars separately from those eaten at home; that distinction is useful when you’re deciding what to make next year.

If the record and shelves stop matching, count what’s there and update the entries. You can continue from the current count without guessing where every missing jar went.

Keeping everything together in The Cantry

The Cantry shows your jars across storage places in one inventory. Logging a batch adds its jars, and the older batches of each product appear first.

When you open a jar, mark it used to update the count. Jars you give away or discard use the same action, with gifted or discarded as an optional reason. Your inventory then shows what remains and where to find it the next time you’re looking for something for dinner.
