Sour IPA

Sour IPA integrates controlled acidification into an IPA base, producing a bright, refreshing beer where hop aroma and acidity co-exist. Compared with standard IPA, it is sharper, tangier, and less bitterness-centered.

Defined by combining hop-forward character with deliberate souring, creating a tart yet aromatic profile.

Also known as: Sour IPA; Tart IPA

Variant of IPA - Within the Expressive Ales, defined by a clearly dominant sensory driver such as hop intensity, yeast expression, strength, or acidity.

Why Sour IPA tastes like it does

These structural drivers explain its characteristic flavour balance.

  • Sharp, fast-developing lactic acidity from kettle souring.
  • Moderate fermentation expression with balanced ester and phenolic development.
  • Short maturation period.
  • Pale ale malt provides a clean, lightly biscuity base with moderate body and a gentle malt backbone.
  • Very high hop aroma intensity provides powerful bitterness and strong hop aromatic presence.
