Flask - a lot of us were having some fun. That's what happens on this forum when guys get into the hobby to the level that some of us are at....your question was a good one and deserves an honest answer, so forgive me and anyone else who went sideways with a humorous or not so humorous response.
I think everyone would say that pilsner malt lends a bit of "graininess" to a wort as compared to some other 2 row malts, but graininess is subjective, so as Denny says - he perceives it as hay/ grassiness for Weyermann's pilsner malt, but probably prefers Best Malz for a pilsner malt. I have used a lot of different malt and currently may favor Avengard pilsner over some others, but some may like Weyermanns for its flavor, despite the hay. All said and done, you are probably right that pilsner malt of a manufacturer is a little more grainy than another malt of the same maltster.
