What is the standard head size on a pour of real ale?

The standard head size on a pour of real ale is approximately one inch. This measurement is important because the head contributes to the aroma and overall sensory experience of the beer. A well-poured pint of real ale should have a creamy, stable head that enhances the flavors released from the beer.

In the case of real ale, especially styles served traditionally cask-conditioned, an inch of head is ideal to allow for a bit of oxidation, which can help bring out the beer's character. A proper head also ensures that the carbonation experience is balanced and not overwhelming. While variations may occur due to specific styles or personal preferences, the one-inch standard serves as a guideline for achieving the optimal pour that respects the traditions of real ale serving.
