Ah, the age-old question that pops into your head just before you decide whether to have a second glass. While the provided texts focus on a single glass, we can do some light maths to solve the mystery of the bottle.
According to the experts at Drinkaware, a single medium (175ml) glass of typical-strength white wine has about 2.3 units of alcohol. A standard bottle of wine contains 750ml, which means you get a little over four of those medium glasses from it. A quick calculation reveals that the entire bottle is therefore home to roughly 10 units of alcohol.
Considering the NHS advises men and women not to regularly exceed 14 units a week, that single bottle of Pinot Grigio represents a very significant portion of your weekly budget. In fact, polishing one off gets you most of the way to your recommended limit, so it's worth keeping that in mind before you plan a week of solo wine nights.
