Keep in mind that a drink is defined as 14g of alcohol. A drink of wine is four to five fluid ounces, but most people pour much more than that when they have a glass at home. It's similar with beer. A 12oz bottle of 5% ABV beer is a drink, but many craft beers are 7-10%. It's easy to have a couple of beers or glasses of wine and have 3-4 drinks in the process.

Yes and even drinking that quantity of high ABV beer or large glasses of wine that you describe and you'd still have to do it every day of the week to hit 21 drinks a week.
It is, as suggested upthread, an incredible amount of alcohol to describe with “as little as”.
