Structured on roasted malt integration and balanced attenuation, forming a versatile dark ale base adaptable across sub-styles. Soft, toasty, and mildly chocolatey with restrained hop bitterness.

Why Porter tastes like it does

These structural drivers explain its characteristic flavour balance.

  • High roast level gives strong dark colour, pronounced roast bitterness and clear astringency with intense roast aroma.
  • Medium roast provides classic chocolate/roast aroma.
  • Medium toast increases toasted/melanoidin character with some sweetness and light astringency.
  • Classic English ale yeast with balanced fruity esters and a gentle, malt-forward profile.
  • Moderately hard water sharpens hop brightness and increases minerality while slightly reducing fullness.
