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.
