A strange smell was coming from DS16's cupboard and so I tried to find out what was causing that odour. When I opened the cupboard I found a conical flask with a cloudy liquid inside of it + airlock on top of it. This was clearly a fermentation setup. When I spoke to my DS about this he admitted that the liquid inside of the flask is yeast, water, sugar and yeast minerals and so the goal is very clearly to produce alcohol. I'm assuming it's because he's attending a party soon and so instead of going through the hassle of buying alcohol whilst under 18 he took matters into his own hands.
AIBU to be very angry at my son for producing alcohol? How should I approach this situation? Also is it uncommon for teens his age to be drinking or producing their own alcohol? Should I be concerned?
