A taster is a small GRAV® glass hand pipe, consisting of a short piece of tubing with a restriction near one end. The space above the restriction serves as a bowl, while the rest of the tube is a simple mouthpiece. Other companies call similar products one-hitters, bats, or even chillums. GRAV® features tasters in several of our collections. Some of our higher end collections, such as Jane West and Upline, feature tasters with additional design features, but all tasters are fundamentally a straight tube with a low-capacity bowl at one end.
