Unger und

· Modern Unger und Klein on Heinrichsgasse is the rare Innere Stadt wine bar that has been open long enough to feel inevitable. The merchant-and-bar hybrid — founded in 1995 by Carl Unger and Ulli Klein — built much of Vienna's modern wine retail vocabulary, and the bar side remains a working drinking room rather than a shopfront.

The list privileges Austrian classicism: Knoll, Pichler, Bründlmayer, Heinrich, Tement — with a small but stubborn Riesling-from-elsewhere section (Mosel, Alsace, Clare Valley). The by-the-glass programme is honest: eight options under €9, refreshed monthly.

The kitchen is small: charcuterie, smoked trout, the city's correct Liptauer. Fifth because it remains the most reliable serious-wine first stop in the first district, with prices that have refused to drift.
