Every commercial rye beer I've ever tasted had no rye flavour to it at all. It's a shame too, cuz I share the love of rye. Somebody (can't remember who now) on this site told me that caraway is often thought of as rye flavour since it's added to rye bread so often.
I've done a little research on caraway & found some info that says it tends to inhibit fermentation (caraway, not the rye), this has sort of thrown a wrench in the worx as far as my rye/caraway use in brewing goes. Hope your rye barleywine turns out well. Regards, GF.
