Roasted malt aromas and flavors including cocoa are acceptable at low levels. A very low level of malt sweetness may be present and balanced by acidity from *Lactobacillus*.

Not present
Fermentation Characteristics:
*Brettanomyces*-produced aromas and flavors should be absent or very low. Fruity esters expressed as cherry or green apple attributes are apparent.
