so, the first time my father tried to make sparkling wine, I was still living with my parents.
One evening, I was just minding my own business in my room, when I suddenly hear my father call me name with a tone of desperation in his shout, «come, quickly!»
I get to the kitchen, that was on the other side of the house, and my father was completely *drenched*, and the entire kitchen, walls and ceiling were painted with that classic purple color that you get when you stain something with red wine.
Wine had covered literally every surface, and my father was standing there, wine dripping from his glasses and clothes, arms wide but pointing down, you know, like you do when you are the victim of a surprise water bomb. Or wine bomb, as the case may be.
In front of him, one of those 2L Coke bottles that we often reuse for water or, as in this case, wine. Except that the bottle was almost completely empty, maybe one last finger of wine left in it, because the rest of the wine was *everywhere else*.
Apparently, the website where he had taken the instruction from had a typo, and the proportions of must (wort? not sure what the name is in English; the thing that you ferment to make wine) to wine was wrong by a factor of TEN (this was way before LLMs ruined the Internet BTW, but errors still happened of course).
So he *had* succeeded in making sparkling wine, except that the amount of CO₂ in it was *explosive*, and the moment he unscrewed the cap, the pressure just made the whole thing *blow up*.
This was a very instructive experience about things such as the amount of effort that it takes to clean a whole kitchen sprayed in wine, but also on the mechanical resistance of the 2L Coke bottles.
