Style Description

This is the description of how the Classic Irish-Style Dry Stout style of beer should taste, feel and look. However, there may be perfectly fine beers in this style that fall outside of these ranges and descriptions. This information is just to show the most commonly accepted ranges for the Classic Irish-Style Dry Stout beer style.

Head retention should be persistent

  • Color: Black
  • Body: Medium-light to medium
  • Malt Flavors & Aromas: The prominence of coffee-like roasted barley and a moderate degree of roasted malt aroma and flavor defines much of the character. The hallmark dry-roasted attributes typical of Dry Stout result from the use of roasted barley. Initial malt and light caramel flavors give way to a distinctive dry-roasted bitterness in the finish.
  • Hop Flavors & Aromas: European hop character may range from not present to low in aroma and flavor
  • IBUs/Bitterness: Medium to medium-high
  • Fermentation Characteristics: Fruity esters are low relative to malt and roasted barley as well as hop bitterness. Diacetyl is usually absent in these beers but may be present at very low levels. Slight acidity may be present but is not required.
  • Common Ingredients: Guinness is made using roasted barley, flaked barley, and pale malt, but other breweries don’t necessarily use roasted barley; they can use chocolate or other dark and specialty malts. Whatever combination of malts or grains is used, the resulting product should be black. Cork-type stouts are perhaps closer to historical London-type stouts in composition with a varied grist not dominated by roasted barley.
  • Commercial Examples: Beamish Irish Stout, Guinness Draught, Harpoon Boston Irish Stout, Murphy's Irish Stout, O’Hara’s Irish Stout, Porterhouse Wrasslers 4X
