Yes. Arguably, because amateurs are not cost bound, they tend to make a less "containinated" product due to the way the collection and blending works.
You discard the foul flavors and harse volatiles that commercial folks keep for cost.
>Can you guarrantee that nothing goes wrong, that the product is tested for contaminations every time?
Life isn't about that kind of guarantee. You don't practice the same level of food safety at home as you're required to maintain in a professional environment.
Life, is about risk acceptance.
Given the variability of quality and flavor among vodkas, this is not quite true. Water mineralization, number of distillations, type of filtration, terroir and remaining "impurities" from the specific mash used. All of these affect the character of the vodka just as they do any spirit. That's why no one takes vodka distilled a million times seriously, if you can even call it vodka.
(And that excludes things like barrel-aged vodkas, like the venerable starka, or a well-made bimber which cannot be accused of lacking character.)
Similarly, perhaps the state ought to regulate the use of refrigerators in a residential setting since various failure modes there can easily land you in the hospital.
Enough people have contracted botulism poisoning by storing chopped garlic under oil in their fridge that the FDA has a warning about it on their website. So I suppose that would also be acceptable to regulate? Or perhaps just cooking oil in general? After all, it's quite flammable and people commonly start house fires when frying things.
While we're at it, perhaps canning things at home ought to require a permit?
The standard that "thing could pose a hazard therefore regulation is acceptable" is far too broad a criteria as it applies to approximately everything that exists and entirely disregards individual freedoms.
> It requires care and craft
A fine whiskey? Sure. The equivalent of vodka? Don't be ridiculous.
> alcohol is not only a drug but a transformed product
It most certainly is not. Distillation concentrates something that is already there.
Alternatively, fried eggs are a transformed product but at that point the term as used is so absurdly broad as to be rendered entirely useless.
