Bakers yeast and alcohol

[Yodaspike]

Just a quick one.
At what abv will bakers yeast and wild yeast die off.
Wondering since my first mash was only fresh apples juiced, with 250g sugar per litre and 5g of yeast, this was if i recall a 5lt mix, strugled to keep it cool to stop fermenting after a week, ended up going on for 3 weeks till ALL the sugar was turned to alcohol, so was making cider but came out more like savanah, with a big kick, so took 500ml small pot still and pulled out 160ml of alcohol, no cuts....soooo....how did this happen, as it would mean that there was more than 20% in there, altough never tested the abv so....maybe just lot of water with the distilled product?
