That said, I really dislike this malt. Its indeed well modified,with the high kolbach and low protein. I get funk from this... Wet hay and apple peel, I call it "dirty".
Was it perhaps bad before you used it? As a data-point, I taste malts before buying and using and this has been a go-to base malt for me. No problems.
No, it was fresh and brewed properly. I am not alone. Many Brewers in my circle from across the US claim the same. I guess if you can't taste it all the more power to ya'll!
My beers were in front of a lot of people this summer, some professional. That kind of tasting feedback never came up. Most kindly, please think of it as a data-point in the field, less "if you can't this then you" kinda thing.
