I have been using Great Western 2 row for the past 20 years. As homebrew shops around me keep closing, I want to support my guy but he has Rahr 2-row. Has anybody interchanged their 2 row malt and noticed a huge difference? Even a slight difference? OMG Change is scary!
They are all slightly different but not hugely so. I have done some SMASH blonde ale type beers with different brands of two-row to compare. You can taste slight flavor differences. When I use different two row in more complex recipes like IPA, APA, porters, I don’t notice much difference. Of course, YMMV.
Another potential difference is extract. Some yield more SG points for the same amount of grain.
