No, this does not mean the beer is past its expiration date. An old ale is a medium-strong British dark ale.

Old Ale's name originated centuries ago because it was a mild ale that was aged a year or more before drinking. It was the mixture of expensive old ale with inexpensive mild that became the basis for the porter style. These beers are typically dark, rich, and sweet with notes of fruit and molasses. Best served at (50 degrees F).

Dark Amber to brown in color, old ales are medium to full bodied with a malty sweetness. Hop aroma should be minimal and hop flavor can vary from none to medium in intensity. Fruity-ester flavors and aromas can contribute to the character of this ale. Bitterness should be minimal but evident and balanced with malt and/or caramel-like sweetness. Alcohol types can be varied and complex.

A distinctive quality of these ales is that they all undergo a prolonged aging process (often for years) on their yeast either in bulk storage or through conditioning in the bottle, which contributes to a rich, often sweet and complex estery character. Some oxidation and diacetyl character may be evident and acceptable. Oak aged character is acceptable. Chill haze is acceptable at low temperatures.
