i have been done three 10 gallon pilot batches and a 3 bbl maiden brew using a combination of us-56 yeast and rahr 2-row malt. i have also been using oxygenation and pitching dry yeast at a rate of about 500 g yeast /125 gallons wort (22 g/5 gallons for pilot).
i have been experiencing attenuation of over 90% even with 10% crystal malt. i have never experienced this kind of attenuation. with all the improvements in my pilot and commercial brewing over homebrewing, i'm not sure what to attribute these attenuation levels, if anything.
is this a normal attenuation level for us-56? could the rahr malt have something to do with it? i don't mind the attenuation, its just a different issue than i've had with most of my homebrewing which typically seemed somewhat underattenuated.
thanks.
