Why this hi ball earns its place
At 591ml, the Capella Stack cooler is the larger serve—long mixers, generous pours, soft drinks with ice and garnish. It's polycarbonate, which means unbreakable resilience in settings where conventional glassware fails under impact and thermal stress. For beer gardens, outdoor venues, resort pools, or any casual hospitality running volume, that durability is a material efficiency that compounds across hundreds of serves.
The larger capacity reduces pour frequency, which matters in high-volume service. You're pouring less often per guest, but each pour looks generous—it's the visual confidence of a full glass. 591ml sits perfectly between spirit-forward serves (where you want visible ice) and fully-dressed long drinks (where the glass needs breathing room).
Polycarbonate ages gracefully under commercial use. It won't crack from thermal shock, won't splinter if dropped, and doesn't require careful handling. After 500+ dishwasher cycles, minor frosting develops, which is purely cosmetic. You're rotating stock based on cosmetic wear, not breakage replacement—a dramatically different economics from conventional glass.
