Fun idea from Clawhammer Supply. Somebody let me know if you try this.
"Love sparkling water? We did too, until we discovered hop water. You might not have heard of it before, but hop water is tastier, healthier, and it's super easy to make. In this video, we'll tell you what it is, how to brew it (and tweak it to your liking), and how to bottle/keg it so you have an infinite supply at the ready.
In short, it's carbonated water brewed with hops instead of fruit/artificial flavors. Hops are typically known as being one of the primary ingredients in your favorite beer styles. They're what gives beer its characteristic bitterness and flavor (they're also really good for you)."
