Step by Step: Rehydrating Dried Yeast Using Rubbermaid TakeAlong Containers

I have used Bel-Art Lab Quality Autoclave Safe Bottles to rehydrate yeast for years.  I bought a dozen of these back in February of 2011 and still have 9 or 10 unused containers.  These are great bottles and have worked really well for me.

Although the per container cost of these is generally reasonable, buying a dozen of these lab containers can be a bit pricey.  I stumbled across the Rubbermaid TakeAlongs line of containers while looking for a less costly alternative.  They are food safe, leak proof and microwave safe.

First a look at the container…

Rubbermaid TakeAlongs Twist and Seal Food Storage Containers, 2-Cup, Clear, Set of 3Stock Image

In the package.

Side of Box: Twist&Seal – Twist-tight, leak-proof seal.  Handles stay cool when food is hot.

On the lid: Remove lid before microwaving

Recycling code is PP 6, 2 cup/473 mL capacity, Top Rack Dishwasher Safe, Microwave Safe (symbol), Freezer Safe (symbol), Made in USA

Rehydrating Yeast Using this Container…

Disclaimer:  This process involves hot liquids and steam.  Use caution as this is a dangerous process and you could get hurt.  Always read and follow manufacturer’s instructions.

I used Fermentis Safale S-04 dried yeast for this process.  Here are rehydration instructions for this yeast.  Fermentis Safale US-05 directions are identical.  Check with your yeast manufacturer for specific rehydration instructions.

The instructions say to use 10 times the weight of yeast being rehydrated.  11.5 gram packet equates to 115 grams.  I used the my - Fast Weight MS-500 Digital Scale to do the heavy lifting here.

Since I use US-05 quite a bit, this is a pretty common weight for me, so I marked the side of the container with an Industrial Sharpie so I don’t have to weigh this out every time.

Next I placed the container in my microwave, with.  Remember… Remove the lid before microwaving.  I chose to set the lid loosely on top to allow the steam to sanitize the inside of the lid.

Next I carefully attached the lid.  Again: If you decide to do this, be careful and do it at your own risk.

As the container cools, the sides will collapse a bit (as pictured).  After this was all said and done, the sides bounced back pretty well but not perfectly.  I cooled the container and water under running tap water until it reached my desired temperature.  In this case 85 deg F.  The instructions say 80 deg F + or – 6 degrees.  I took the temperature with a touch free IR thermometer.  You could also use a sanitized digital thermometer.

The next step is to sprinkle yeast in the rehydration water.  I re-attached the lid and, per the directions, let it stand for 15 minutes or so.

The directions say to gently stir for 30 minutes.  One of the beautiful things about using a container like this, with a lid, is that you can swirl instead of stir.  That keeps airborne bacteria and wild yeast to a minimum and you’re also not digging around in your yeast, with who knows what, for 30 minutes.  I swirled this occasionally and came out with this result.

End product.  Hey this looks like yeast!

These are food safe and microwave safe.  The leak proof lid allows you to minimize contact with the outside air.  This worked well for me.

With a pack of three you can use one for yeast and the other two for general storage around the brewery.

If you’re a close reader of Homebrew Finds you’ll know that I’ve been playing around with a couple of rapid prototyping-related products for use with homebrewing.  One is littlebits, the other is a XYZPrinting Da Vinci 3D Printer.  Related to the latter, I’ve printed out a few interesting things including multiple tap handle designs and a fair number of… chip clips :).  I think the technology has a lot of potential.

Anywho… there are a number of stir plate STL designs already out there.  Existing Stir Plate STL projects (at least that I’ve found) tend to use “the fan I had laying around”.  I plan to source this specific cooling fan and put together a Stir Plate design that works with it.  I like this model because… 1. It’s a good size (4.7″ square), 2. Is already wired for AC and, 3. Includes a variable speed function.   If you’re experienced designer and want to help, I’d be happy to work on this with you.  Just Email Us and we’ll get rolling.
