Dry-yeast dosage bands by strain type, in grams per hectolitre.
Used for a dry strain whose maker doesn't publish a figure. Fermentis print
50-80 g/hL across their ale range and 80-120 across their lagers, and
Lallemand's numbers are in the same range, so these are the manufacturers'
figures, not something we derived.
We need them because a cell-count target doesn't work for dry yeast. The
1.5 M cells/mL/°P lager rate is liquid-yeast practice from White &
Zainasheff, and dry yeast arrives with the glycogen and sterol reserves a
liquid pitch has to build in the wort. Judged on cells, a by-the-book
Fermentis lager dose looks like a heavy under-pitch: five sachets where the
maker asks for under two.
