Don't expect any exceptional aroma from Marynka, this is primarily bittering hop. It is not a "clean bittering hop" like Magnum, so it has plenty of flavour. To me it shows "east European character" - grassy, earthy, woody, with spicy finish. Unpleasant spiciness and tart aftertaste might be present if used too much as flavour addition.
My preferred schedule is 20 gms pellets as bittering and flavour additions each, then 10 gms paired with 15 - 20 gms of other neutral aroma hops (Hallertau, Mt. Hood, Liberty) for 10 or 5 mins. This should give ~30 IBU and that's for 21 ltr "standard strength beer" (1.048 - 1.053). Anyway I rarely use as much Marynka alone, more often pairing 10 gms with Sybilla, Lubelski or other east European hop for bittering and flavour additions.
