Mazurski American Pils

Golden, iridescent, with a delicate mist scattered inside, quite loud foam, medium mesh, slowly reducing to a durable ring. The aroma lacks the freshness you'd expect from an American hopping. There is a combination of Pils malt, some spicy aromas and diacetyl. The taste is classic, but in Czech ... and although the finish is hoppy and with a pleasant bitter counter, the beer is generally quite a mash-mash. Hops not aromatic enough for an "American", since light and since rice flakes emphasizing dryness, why would oatmeal increasing the fullness?
