What gives Robust Porter its character

These structural drivers help shape its characteristic sensory profile.

  • High roast level gives strong dark colour, pronounced roast bitterness and clear astringency with intense roast aroma.
  • High grist intensity provides more extract and fermentable material, supporting higher gravity and alcohol strength alongside fuller body, slightly greater sweetness and a longer finish.
  • High crystal addition adds caramel sweetness, deep amber colour and round malt richness.
  • Cold conditioning in a bright tank allows suspended material to settle, improving clarity.
  • High toast strongly deepens colour and increases toasted/melanoidin malt aroma.
  • Moderate hop loading contributes to perceived bitterness and adds some hop aroma.
  • Polyphenols from hops or malt can contribute to haze.
  • Dark crystal provides intense dark-caramel and dried-fruit character in the malt aroma.
  • Melanoidin malt adds intense maltiness and strong melanoidin aroma.
