This gorgeous glass has a Northern Brewer hop logo laser etched on the bottom. The laser etching creates tiny rough spots on the surface of the glass that act as nucleation sites where CO2 bubbles are able to form. The bubbles gather and rise to surface in a continuous cascade that bursts forth at the surface of your beer and liberates the lush aromas locked within. The ascending stream of bubbles replenishes the head and draws your attention to the appearance of the beer while delivering the aromas directly to your nose, all of which enhances the sensory experience of beer tasting. Because a great beer deserves a great glass.
