So i see there are now hard seltzer homebrew kits, I’ve had some commercial offerings and been kinda ‘meh’ on them, I’d probably order a seltzer over a Miller Lite, but I’d take any real beer hands down.
So anyway, maybe i just don’t get it, but “brewing” hard seltzer seems silly to me… shouldn’t you just make it by…
Dump some fruit juice in the keg
Dump a pint or fifth of Everclear in the keg
Top-off the keg with water (maybe boiled and cooled, or distilled)
Force-carb it to a zillion volumes.
Actually this seems like the perfect application for a Soda Stream.
