Alchemi 7 oz Double-Walled Aerating Bourbon Glasses, Set of 2

A Double-Walled Bourbon Glass With Internal Aeration Ridges That Change What You Taste

The Alchemi 7 oz Double-Walled Aerating Tumblers by Viski are a set of two borosilicate glass bourbon tumblers engineered around two functional details that work together: an internal tulip-shaped wall with raised aeration ridges, and a faceted geometric outer wall that creates a sealed air gap between the two layers. The ridges on the inner wall break the surface of the spirit as it sits, dispersing ethanol vapor and directing concentrated aromatics upward to the rim — the same principle as a Glencairn, but in a stemless double-walled tumbler. The air gap between the walls insulates the glass, keeping it cool to the touch and preventing condensation on the exterior.

• Internal aeration ridges disperse ethanol and concentrate aromatics at the rim — the inner tulip wall has curved fin-like aeration ridges that break the surface of the spirit and create airflow within the glass; as ethanol disperses upward and outward, the heavier aromatic compounds — vanilla, caramel, oak, fruit — are drawn to the surface and concentrated at the narrowed rim where your nose sits; the result is a noticeably more expressive pour from the same bottle; works with bourbon, scotch, rye, cognac, or any spirit worth nosing
• Double-walled borosilicate construction — no condensation, cool to the touch — the sealed air gap between the geometric outer wall and the inner tulip wall insulates the glass; the exterior stays dry and cool regardless of what’s inside; no condensation rings on the table, no warming from your hand through the glass; the borosilicate glass is thermal-shock resistant and dishwasher safe; the double-wall also creates the visual effect of the spirit floating suspended inside the outer shell
• Faceted geometric outer wall — angular planes, sculptural silhouette, substantial in hand — the exterior is cut with flat angled panels at the lower half that transition to soft curves at the upper rim; the shape is architectural and sits solidly without a base; the glass reads as a design object as much as a functional one; the two glasses are identical and nest cleanly for storage or gifting

For Bourbon Drinkers Who Actually Want to Taste What’s in the Glass

Pour a finger of your best bourbon, let it rest for thirty seconds, then nose the rim. The aeration ridges do the work of opening up the spirit without dilution or waiting. Works equally well with scotch, rye, cognac, or aged rum. A strong gift for whiskey collectors, home bar enthusiasts, or anyone who prefers their spirits with intention. The double-wall means they look right on a shelf and function correctly in hand.
