Yeast on a plate ready to go into a 5ml vial |
Stepped up from 2ml to 20ml |
The yeast was one I'd made a plate of back when I brewed the leichtes weizen. It was a simple matter to use my sterilised inoculation loop to scoop up some yeast and deposit it in the vial. Once the yeast was happily fermenting in the vial I stepped it up into a mini erlenmeyer, then into a 250ml erlenmeyer and finally into my 2L erlenmeyer. Several steps but it worked out very well and each time I do it I feel a bit more confident about my processes.

This brew is pretty similar to the leichtes weizen I brewed for the competition. I went for a 30 minute ferulic acid rest and was planning on a gravity of 1.046. My efficiency was a bit lower than I expected, something that seems to happen often when I use wheat, and I ended up with 1.043 in the fermenter. Will and Bernie helped out with this one and it all went nice and smoothly.
