So random question but How much alcohol is tastable?

I’m asking because how much is alcohol is real alcohol?

Like if put 2 shots of vodka into 2kg liquid milk chocolate, and put it into 20 100g bars of chocolate and give it to my alcoholic and slightly workaholic Romanian, British, Russian and Indian homies, how much of that alcohol is tastable?

My Romanian homie is a 86 yr old grandpa war veteran

My British homie is a 19 yr old broke (I don’t understand how he’s broke) college guy

My 2 russian homie are two 23 yr old twins with ADHD problems.

And my Indian homie is a 16 yr old who has been adopted by the grandpa.

I can’t drink alcohol or eat anything sweet because of tooth problems.
