This is also true (or very similar) in the US. 14 units is certainly closer to 14 shots than 7.

> In the United States, one "standard" drink contains roughly 14 grams of pure alcohol, which is found in:

> * 12 ounces of regular beer, which is usually about 5% alcohol

> * 5 ounces of wine, which is typically about 12% alcohol

> * 1.5 ounces of distilled spirits (= 1 US shot), which is about 40% alcohol

Edit: although, 25mL is far less than 1.5oz. Different units, then.
