Fermentation characteristics

Fruity esters can contribute to the character of these beers. Alcohol types can be varied and complex. A distinctive quality of Old Ales is that they undergo an aging process, often for years. Aging can occur on their yeast either in bulk storage or through conditioning in the bottle. This contributes to a rich, wine-like, and often sweet, oxidized character. Complex estery attributes may also emerge. Diacetyl is usually absent in these beers but may be present at very low levels.

Additional guideline notes & competition context

Low level attributes typical of wood-aging such as vanillin are acceptable. Brettanomyces and acidity reflect historical character; low level attributes such as horsey, goaty, leathery, phenolic, etc. and acidity may be present and balanced with other flavors. Attributes arising from liquids previously aged in a barrel, such as bourbon or sherry, should not be present. Beers that exhibit such attributes are categorized as wood- and barrel-aged beers. When using these guidelines as the basis for evaluating entries at competitions, competition organizers may choose to split this category into subcategories which reflect strong and very strong versions, or historic and modern versions.
