I thought I would post my findings in case anyone was wondering.
I did a 10 gallon batch of IPA last month. I fermented 1/2 with Ringwood, and I fermented the other half with 060 American Blend. I happened to have both on hand, and thought I would do a little experiment. I think I recall reading that the Amer blend included Ringwood??
Anyway, both fermented pretty quickly and finished at the same FG: 1.014 from an OG of 1.062. The only difference I noted with that the ringwood was a little more cloudy than the Amer blend at kegging, and that has held true throughout. Even now, with both on tap the ringwood batch is just a little cloudy with the Amer is pretty darn clear.
As for taste, well blind taste tests with three idividuals proved it.....we can't tell the difference at all . They are so similar that we can't taste any noticeable difference at all.
Not sure that will help anybody, but I thought I would post it .
