What gives Flanders Red Ale its character

These structural drivers help shape its characteristic sensory profile.

  • Very high crystal loading creates a rich, full body, deep colour, long finish and intense caramelised special-malt character.
  • Very high attenuation converts a large share of fermentable extract, strongly reducing residual sweetness and body while supporting alcohol formation and a dry finish.
  • Mixed fermentation producing layered lactic acidity and subtle funk.
  • A dextrinous mash leaves more non-fermentable extract, supporting greater body, residual sweetness and a longer finish.
  • Cold conditioning in a bright tank allows suspended material to settle, improving clarity.
  • Foeder aging lowers carbonation and makes small contributions to finish length and oxidation.
  • Yeast in suspension can create a soft, natural haze.
  • Pilsner malt provides a pale grain base with relatively restrained malt aroma.
  • Mixed fermentation contributes additional yeast-derived aroma complexity.
  • A chloride-forward balance supports a fuller, slightly sweeter palate while softening perceived bitterness.
  • Moderate grist intensity provides more extract, supporting somewhat higher gravity, body and alcohol strength.
  • Medium toast deepens colour and increases toasted/melanoidin malt aroma.
  • Dark crystal provides intense dark-caramel and dried-fruit character in the malt aroma.
  • Melanoidin malt adds intense maltiness and strong melanoidin aroma.
