If I can be science nerd for a moment.
Putting a glass of gin in the freezer doesnt freeze the water and allow you to remove the ice, and have a glass of alcohol and glass of water. Both the frozen and the liquid componants will contain alcohol, but the liquid will be stronger.
You can repeatedly freeze and defrost the samples to create increasingly alcholic (and less alcoholic) glasses, but a single freeze wont turn a 20% alcohol/water solution into a glass water and an emptier glass of alcohol, half a dozen freezes is likely to leave your "water" glass, at beer %ages.
Heat distilliation suffers from the same problem, which is why even cheap mass markets like Smirnoff are triple distilled.
You cant just add more yeast to make a stronger drink, alcohol is quite toxic, turbo yeast is merely yeast that can survive very high alcohol levels, but no matter how much you put in, it'll still die at around 17-22%
As a comparison, humans die at around 0.7%
