You clearly don’t know shit about how alcohol is made if you think describing a process that might be virtually identical across dozens or hundreds of brands is adequate to convey the level of detail that consumers use to make purchasing decisions.
For a lot of brands, the process is blending other products to create a specific flavor profile. There is literally no process to describe beyond “the blenders combine things until they find a blend that tastes the way brand X is supposed to taste.” How do you propose to describe such a process without brands? And no, they can’t just describe the individual inputs, because things like wine naturally vary from year to year even with identical processes, which means blends need to use different ratios to get the same flavor for each batch.
