Two drinks each night versus one is quite a difference. It's double the amount of alcohol!

Current recommendation from the Netherlands Nutrition Centre:

> It is advisable to refrain from drinking alcohol, or to consume at most one glass a day. This advice applies equally to men and women.

> Moderate consumption of alcohol at one glass a day may reduce the chance of getting certain chronic diseases, but also raises the chances of getting breast cancer for women. Drinking more than one glass a day, is not beneficial at all, and has negative effects on health. It increases the risks of having a stroke; and getting breast, intestinal, or long cancer.

> The potential benefits of alcohol do not outweigh the negative effects on your health.¹

(Personally, I drink only in the weekends; usually one glass, occasionally two. It prevents making a habit out of it.)

Two drinks each night versus one is quite a difference. It's double the amount of alcohol!

2 bottles of 5% abv beer has a little less alcohol than 1 normal sized glass of 13% abv red wine.

How are you calculating that? One standard 330ml bottle of beer at 5% has a little less alcohol than a standard pour (150ml) of 13% wine. As soon as you move to a pint or 500ml can of beer you go over it. This is why a glass of wine and a bottle of beer are taken as roughly equal in terms of alcohol content.

    330×5% < 150×13%

A glass of red wine is 250ml.

That would get you exactly three glasses from a bottle. That's… not a normal pour of wine in any country.

A standard size bottle of wine (750ml) serves five or six glasses, but the hospitality industry usually goes for five out of a bottle. 150ml (or 5oz) is what you can reasonably expect in restaurants and bars for the average glass of wine.

Do you honestly pour a third of a bottle at a time for wine?

250ml is a standard UK measure of wine.

175ml and 125ml are also UK standards but in a lot of places if you order wine by the glass you'll get 250ml.

In the UK that is a 'large' glass of wine. The NHS¹ calls 175ml 'standard' (slightly more than usual) and 125ml 'small'.

For the UK this is all not that relevant, because there the concept of the 'alcohol unit' is much more ingrained and used in public health campaigns, so you would work with those. E.g., with the recommended upper limit of 14 alcohol units, you could drink a standard glass of wine (175ml) six days of the week (12.6 units), or have a bottle of lager six days of the week and a pint of Guinness on Saturday (13.2 units).

Unless I've made an arithmetic error, those two American-sized beers (12oz each, 700ml of beer total) contain 35g of alcohol, and the American glass of wine (6oz, or 175ml) has 22.75g. Less alcohol than the two beers, but still more than most people should have on a daily basis.
