I tasted this at the Territoriet (The Territory) wine bar in Oslo a few weeks ago. It was a perfect red wine for a warm, humid, but not sunny day in Oslo.
Heinrich grows the grapes after biodynamic principles, though the wine has no certification. It is a 100% zweigelt, underwent a spontaneous fermentation in steel and big oak vats, and had two weeks maceration.
2014 is also in the market, and both are good.
Zweigelt 2013 (Heinrich)
Cherry red. Aromatic, with mature red berries, some green pepper. Quite warm and round in the mouth, but also with light and elegant tannins and a crisp, refreshing acidity.
Price: Low
