The definition of bootlegging is so broad that I think you can even legally be charged with bootlegging if you source your alcohol products for sale from anywhere other than a distributor, e.g. buying in bulk from Costco or a discount liquor place to stock the bar.

In general, I think it typically means illegal transport and sale, since not too many people have historically trusted moonshiners or developed a taste for moonshine. There was that weird moment in the mid-2010s where reality TV caused a huge interest in moonshine, but that was just distillers realizing that they could capitalize on a trend by making unaged 80-proof corn liquor, throwing some cinnamon sticks and apple slices in a Mason jar, and calling it “moonshine.”
