Show me a clip or screenshot of him with the product and I will pass judgement.
Turbo yeast is usually 'messier', producing flavor compounds like diacetyl (buttery), acetaldehyde (green apple, nail polish remover), amyl acetate (fake banana), etc. This usually isnt a problem because the wash is distilled, removing those off flavors in the foreshot or leaving it in the still pot. He isn't distilling it, all that shit is going to be drank directly.
Now some of these flavors arent always a bad thing. Some Chardonnay makers want diacetyl, and I've had really good "banana bread beers" that used amyl acetate to emulate banana flavor. This takes a lot of skill to get the desired effects for your product, and Cobes is just winging it.
tl;dr if he used turbo yeast, its gonna be some real rotgut hooch.
