I want to drink a blossom hill drink which is a small bottle that is 187 ml which contains 12.5% alcohol volume so if I drink two of those small bottles does that mean I’ve drank 25% alcohol in total . I don’t know how this really works .

No. You'll have drunk 12.5% of a larger volume.

So if I drink 4 bottles of 12.5% alcohol , does that mean I still drank 12.5% alcohol??

12.5% is how much of the entire thing is alcohol. Say a bottle is one litre, for easy numbers, 12.5% alcohol means 125ml of that L is alcohol. That means four litres is 500ml of alcohol

I have always been curious about this myself. I am glad you asked this, as it may help.

Honestly, being able to do APV (alcohol percentage volume) sums, especially when drunk, is really useful. Everyone has a good level of how drunk is the right amount. On a full stomach, six beers will get me into the sweet spot so it's good to be able to work out what that is in spirits if I don't have beer

Maths is not my preferred choice of education, therefore it isn't my strongest point. Tbh, I only stop drinking if I am tired or have a stomache ache, so it could be a number of beers to get me to that stage.

Alcohol content which is what is on the label, this represents the potency i.e. how strong a drink is, its the percentage of alcohol in the bottle/glass; but to find out the amount of alcohol you do the percentage x Volume.

But their are all kinds of factors like tolerance, have you eaten that day, mixing of alcohol types, duration of drinking, body type that will all impact how drunk you get in addition to the amount of alcohol.

Here's something useful to remember:

Alcohol units = volume in litres multiplied by percentage. So 25 ml of whisky at 40% alcohol is 1 unit exactly because 40 * 0.025 = 1.
So two of those drinks is 374 ml. At 12.5% alcohol then that's 0.374 * 12.5 ~= 4.7 units. 1 unit corresponds to 10 ml of ethanol.
