I was just reading through the capsule for Homer vs. The Eighteenth Amendment when I noticed that there is no mention of the errors in the scenes of Homer's distillery. Here's some that I saw:
First of all, the setup of the stills in the basement is completely non-sensical. It's too crazy to even bother trying to explain here.
The Cognac, Scotch and Rye all had color. These spirits are all colorless prior to the aging process.
Beer is NOT a product of distillation, yet Homer had his beer "hooked up" to a still. (yes I know that Whiskey is made from a fermented mash that closely resembles beer; but it's not the same thing)
I didn't notice any condensers in the basement that could have even come CLOSE to being up to the job.
The boilers had no obvious heat source: they appeared to be set up on some sort of small table.
There were no reflux columns for the Gin. (or vodka, rum.. etc..)
The stills exploded while not being operated (Homer was in bed) this is impossible.
When Homer was hauling ingredients for the liquor he had a jar of Tequila Worms. Worms are not an ingredient for Tequila; rather they are added during the bottling process, which Homer did not do. (he filled bowling balls)
Homer hauled a bag labeled "sour mash". Sour mash is NOT a grain but rather a LIQUID byproduct of a previous distillation that is saved and in turn added to the fermented mash of the next batch.
