Tokaji Aszú

What is Tokaji Aszú? Tokaji Aszú is a legendary Hungarian sweet wine from the Tokaj region, made from grapes shrivelled by Botrytis cinerea — the so-called noble rot. Produced primarily from Furmint and Hárslevelű in a small wine district that straddles northeastern Hungary and a sliver of southeastern Slovakia, it ranks among the oldest classified appellations in the world, formalised by royal decree in 1757. Since the 2013 vintage, Hungarian regulators simplified the historic puttonyos system: the 3 and 4 puttonyos grades were retired, and every bottle labelled Aszú must now carry at least 150 g/L of residual sugar. The result is a concentrated, age-worthy dessert wine that accounts for less than one percent of Tokaj's annual output.

Terroir and Grapes

The Tokaj wine region sits near the Carpathian Mountains at around 457 metres elevation, with vineyards rooted in volcanic soils — rhyolite, andesite and tuff — overlaid with loess. This geological signature gives Aszú its characteristic mineral backbone and helps anchor the wine's intense sweetness with vivid acidity. The cultural landscape was inscribed as a UNESCO World Heritage site in 2002, recognising centuries of continuous viticulture.

Six grape varieties are officially approved: Furmint dominates with roughly 60 percent of plantings, followed by Hárslevelű at around 30 percent, with Yellow Muscat (Sárga Muskotály), Zéta, Kövérszőlő and Kabar filling out the field. Furmint provides the structure and acidity, while Hárslevelű contributes aromatic lift — both varieties are particularly receptive to noble rot in the misty autumn conditions along the Bodrog and Tisza rivers.

How Aszú Is Made

Aszú berries are picked individually by hand, often into late November or December, once Botrytis cinerea has dehydrated them into raisin-like nuggets of concentrated sugar and flavour. The shrivelled berries are crushed to a paste, then macerated with a base wine or must inside a 136-litre Gönc cask. The puttony itself was the roughly 25-kilogram basket historically used to measure how much aszú dough was added per cask — the unit that gave the old labelling system its name.

Fermentation is slow and incomplete, stretching across years of cask ageing in cool cellars cut into volcanic rock. Finished Aszú typically clears 14 percent ABV while retaining at least 150 g/L of residual sugar. For context, the pre-2013 scale required 60 g/L for 3 puttonyos, 90 for 4, 120 for 5 and 150 for 6 — today only the top two tiers remain, and producers may still print 5 or 6 puttonyos on the label if the wine meets the matching threshold.

Aszú, Eszencia and the Wider Family

Tokaji Aszú is the flagship, but the regional family also includes Aszú-Eszencia (a historical transitional category), the rare Eszencia, plus Szamorodni in dry or sweet styles, Fordítás and Máslás. Eszencia is the unicorn of the group: free-run juice from aszú berries with sugar levels usually between 500 and 700 g/L — the celebrated 2000 vintage topped 900 g/L — and an ABV that rarely climbs above 5 to 6 percent because the yeasts simply cannot finish the job.

The wine's documented history reaches back to 1630, when aszú production is traditionally attributed to Laczkó Máté Szepsi. Vineyard classification began in 1730, and the 1757 royal decree established the closed Tokaj production district as one of the world's first legally delimited appellations — a heritage that still shapes every bottle today.
