Why is alcohol measured in percentages?
Why is alcohol measured in percentages?
I feel like it would be useful to know exactly how much alcohol is in a can or a bottle. Also why is alcohol the only thing measured in percentages and not sugar or caffeine or medicine?

Australia does this right. Everything has a percentage.
Nutritional panels have:
- Serving size
- Servings in the pack
- Energy, sugar, fat salt. etc per 100ml or 100g, and per serving.
Alcoholic beverages have "standard drinks" per bottle which factors in ABV and volume.
I can quickly see that a drink has 9g sugar per 100ml and know it's 9% sugar. Easy.
Isn't this standard everywhere? I know it's like this in the Netherlands. I assume in America they give you the bald eagle feathers per egg or something too.
America give something useful for customers? No way... /s
So, in a drink you show amount of protein as volume per 100ml?
Here's a Starbucks Espresso marked as 2g of protein per 100ml and 4.4g per serve.
Therefore, it is not %. One is g., another is ml.
1ml of water is 1g.
I surely hope that espresso is NOT water.
Sucrose has a solubility of about 200 g/100 mL water. I’m in American so I’ve never seen Australian food labels, but would they really label a sugar-saturated drink as having 200% sugar? I guess technically you can do that, but it seems a bit weird. In my experience % is usually reserved for liquid in liquid solutions, like alcoholic beverages.
The best example is the slab 'o' Coke from Woolies.
Sugar is marked as 10.6g/100ml and 39.8g per 375ml serve (yes, stupidly large), and 24 serves in the pack.
Syrups are typically sold in grams. But 200g of sugar and 100ml of water would be more than 100ml of total product by volume, and 300g by wileight. If anything, it would be labeled 66% sucrose because it's one third water.
Wouldn't it be lower than 8% sugar by volume since sugar is more dense than water?
