Dammit I’ve been making this joke as a hipster business for like 20 years.
I shoulda taken the risk.
Fun fact: you can lie about the source of your water in most states. It’s not well regulated. So you could say "my Alaskan Galacial Melt is $4 for a 10oz serving, my Icelandic volcanic ash filtered water is $6, and my reverse osmosis is $5.
And it’s all tap water.
Ask any brewer how easy it’d be to subtly change your water lines to all be slightly different in taste/feel/quality.
