Why this tumbler earns its place
The double old fashioned is the heavy hitter of bar glassware — the glass that says "serious drink" before the bartender even makes the pour. At 370ml (13oz) and 106mm tall, the Onis Endessa double old fashioned is wide and stable enough to hold ice and spirit without looking stingy, but not so oversized that a single measure gets lost. This is the glass for Negronis, Sazeracs, Old Fashioneds proper, and anything where ice, spirit, and bitters are the whole story.
The curved shape is the detail that makes it work. A straight-sided tumbler feels utilitarian; Onis gave the Endessa line elegance without complexity — the kind of glass a bartender is actually proud to set in front of a customer. It's worth every millimetre of that 83mm diameter, because spirit drinkers see the glass, and it sets the tone for what's coming.
The durability specs are what make it work night after night. Chip resistance means the rim stays intact through hundreds of drinks. Excellent chip resistance on a spirit glass is non-negotiable — every pour puts pressure on the rim, and one chip and the glass is garbage. These are engineered for that. Dishwasher safe means you're not hand-washing your spirit glasses at the end of a busy shift.
