What it is

The maltier, darker cousin of the Flanders red: caramel, raisin and toast carry a softer, mostly lactic sourness. Aging happens in tanks rather than oak, so there is no wood character and the fruit leans towards dried plum and fig. Fuller-bodied and rounder than its red sibling.

Flavor

What a Oud Bruin should taste like, on the three wheels the studio scores every recipe against. The shaded ring is the style’s range on each axis, from 0 at the center to 5 at the edge.

Hops

Hops stay in the background: none of their character belongs.

Malt

Caramel, dark fruit and sweet/honey, with room for grainy, toasty, bready/biscuit or chocolate.

Fermentation

Fruity esters and tart, with room for clean or funk.

Hops that suit it

None on character. The hops in this style are there for bitterness and balance, and any variety whose aroma you would notice is out of place.

Yeasts that suit it

Strains the lab made for beers like this one, whose fermentation character sits inside the style’s wheel. A strain sold by several labs is listed once; its page names the others.
