Switchwater, as we’ve seen the Bottlefly Boys mention and experience, is non-alcoholic but packs one hell of a kick. It was made in Broodhollow via some brewing process involving switchwood bark, found in nearby Stillwood Forest.
The only thing I can think of that comes close to switchwater — whose trademark properties aren’t from alcohol content but some other compound — is absinthe. But absinthe is a spirit, not something you’d drink a pint of.
The original recipe for switchwater has been lost to time. What do you imagine a dark, foamy glass of switchwater to taste like? I hope to make some investigations in real life.
