Features

TASTE THE DIFFERENCE – H2OPS is the original award-winning craft brewed hop water with that authentic plant-based goodness you can taste. We proudly brew using the whole hop and never dose with hop extracts or hop oils, which can taste synthetic. Our premium hop selections and proprietary brewing techniques result in the perfect balance of citrus, floral and subtle bitter notes; all from the hops! And without the yeast or grains in beer, our hop water is gluten free and simply refreshing.
THE REFRESHING ALTERNATIVE TO BEER - H2OPS is the perfect “go-to” when you are not drinking or even when you are. Many use as a “session extender” to stay hydrated at parties and watching sporting events. If you are going to drink water, it might as well be hoppy.
