Saving Dry Yeast With a Vacuum Sealer!

I periodically brew small batches that require less that a full packet of dry yeast. See: Small Batch, All Grain Stove Top Brewing + Water Calculation Spreadsheet. For that matter, sometimes larger beers require a full packet plus.
To save money and reduce waste, I use my vacuum sealer to store partial packets of dried yeast.
Here’s the procedure I use…
- Determine the proper amount of yeast using a pitching rate calculator. If you don’t have a pitching rate calculator, sign up for a free non-expiring Brewfather trial account.
- Prepare the proper amount of re-hydration water. Generally, you’ll prepare 10 grams of water for every one gram of yeast needed, but consult manufacturer’s directions.
- Put the prepared rehydration water on an accurate gram scale – I use the AWS-100 from American Weigh [Hands on Review]. Make sure the scale has a “tare” feature or otherwise account for the weight of the container and water.
- Zero the scale out using the tare feature.
- Cut the yeast packet open and slowly pour the yeast into the rehydration water. Careful, there’s no going back if you pour too much. 🙂
- When I get the amount of yeast I’m looking for, I immediately seal the yeast packet (if it’s a mylar type material) using the heat strip sealer on my vacuum sealer.
- I write the amount of remaining yeast on the packet using a Sharpie and then seal that in vacuum bag for additional protection.
- This is quick and easy, reduces waste and saves money.
