Had a draft from the brewery in Bruges. Color is a rich dark brown with a significant head. Nose is strong with spice notes and caramel roastiness. Taste is smooth, slightly tart, malty and sweet. Lots of plum, raisins and caramel. A nice if not wonderful beer. Strikes me as good but nothing fancy.

Copenhagen 10/3 2022. 33 cl bottle from Beerdealer web-shop. Red version of Bourgogne des Flandres strange tower design.

Pours clear amber with a red hue and a mid-sized white head m. Settles as a thin unbroken layer of foam covering the surface of the beer. Substantial lacing.

Aroma is medium intense with a slightly vinous odor of sweet sherry with a light tart twist. Sweet chocolate, caramel and sweet apples. Tart notes of citrus and unripe berries.

Light carbonation. Slightly thick, oily, soft, lightly tingling texture.

Flavor is medium intense with a medium strong sweetness followed by a lighter tart sourness. Lingers for a bit. Finish semi-dry.

Not very sour for a Sour Flemish.

On tap at the brewery in Bruges.

Pours a brownish red with fine, thick foam.

Smell is slightly sweet and malty, with notes of cherries and raisins.

Taste is a bit more subdued thah I expected, given the ABV. Nice woody notes mingle with some raisins, cherries and vanilla.

Mouthfeel is medium and a bit chewy, well carbonated.

Overall, a nice beer, that is dangerously drinkable for the ABV.

Poured from tap at the brewery in Brugge. Pours a burgundy to dark brown, with a nice white head. Nose is sweet cherries, a tad funky, and nutty. Fairly subtle. Taste is caramel, vanilla, bread, and wood. Definitely getting nuts on the taste as well. Maybe a bit of funk in there. Definitely a subtle taste as well. I was expecting something a bit more bold. Mouthfeel was quite creamy, and the alcohol was well hidden.
