  • Color: Dark brown to black
  • Clarity: Beer color may be too dark to perceive. When clarity is perceivable, chill haze is acceptable at low temperatures.

  • Perceived Hop Aroma & Flavor: Optional, but if present should not upset the overall balance.

  • Fermentation Characteristics: Oatmeal is used in the grist, resulting in a pleasant, full flavor without being grainy. Fruity esters are not present to very low. Diacetyl is usually absent in these beers but may be present at very low levels.
