What is the typical CO2 volume range for British cask ale?

The typical CO2 volume range for British cask ale is indeed between 1.0 to 1.5 volumes. This lower carbonation level is characteristic of cask ales, which are traditionally served without additional forced carbonation. The gentle carbonation enhances the mouthfeel and allows for a smoother and more subtle presentation of the ale's flavors and aromas.

Cask ale often undergoes a secondary fermentation in the cask itself, which contributes to its natural carbonation, but the intention is to maintain a softer profile compared to highly carbonated beers. This results in a traditional, draught-style drinking experience that complements the malt and hop characteristics of the ale without overwhelming them with bubbles.

Higher volumes of CO2, such as those in the other options, are generally associated with other beer styles, like lagers or modern ales that are often forced carbonated.
