I have just finished a 500g block of Fermentis US-05 yeast that I repackaged in October 2020 into 20g sachets. I vacuum packed them and kept them in the freezer. Every packet worked and I never had a problem. It is one of the yeasts that I use most frequently hence I get through a 500g block in about 10 months.
Today, I am repackaging another block. This time I am repackaging into 16g sachets. I got 30 sachets out of a 500g block. I vacuum packed each one and then put 5 into a sealed pack that will be kept in the freezer until needed. An opened pack of 5 is always in the fridge ready to go!
The 500g block costs under £40, so each sachet works out at just over £1. And this is for 16g rather than 11g in the standard packet (that costs £2.75).
