Re-using yeast

Yeast is collected in the trub container and can be used for a second time. Collect the yeast after the first trub container removal. Yeast can be re-used up to 5 times (depending on the yeast). Using the method below has been successfully tested up to 4 times.

I have (re)used the Julinius Saf-ale mixture for 3 times. For me the third time gives me the best overall taste.

The yeast from the pictures below was stored for over 2 months in the fridge and successfully re-used. I would recommend to use a magnetic stirrer and DME in order to make a yeast starter.

Step 1 - disinfect the trub container

See picture 1 below.

Step 2 - collect the yeast in a (disinfected / sterile) jar

See picture 2 below.

Step 3 - Storage

Refrigerate the yeast (at about 5 degrees Celsius). You should be able the store the yeast for a couple of weeks, maybe more, but not many months.

Step 4 - Re-use the yeast

Take the yeast out of the fridge when starting the MiniBrew session. Disinfect the jar and open it with clean carefully washed hands. Add a little sugar (1 cube) and put a piece of disinfected cloth on top of the jar. Let the yeast sit a room temperature when you start your brew session.

Note: when I re-use the yeast I brew the same kind of beer with this yeast.
