I just got some. Been looking at the suggested rates, which seems to vary from Wyeast to the manufacturer, even the packaging from Australia.
The package suggests 1.5 grams for a 5 gallon batch, yet when I run the math at 4 grams/hl, I get nearly a half (0.83g) for a standard 5.5 gallon batch. 4 grams/hl is at the high end of the Wyeast recommendation. Anjiomoto's product sheet says to dose based off total batch size, rather than liquor and boil sizes; and provides separate dose suggestions for use in mash and boil.
What dosages have you used?
