Vessel Profiles
The engine catalogs 22 vessel types; 8 are featured here with calibrated thermal conductivity, wall thickness, and material properties. The glass changes the drink.
Coupe
GlassThe workhorse of up cocktails. Elegant, wide bowl, fast warming due to thin glass and stem heat transfer.
Nick & Nora
GlassSmaller, deeper bowl than coupe. Reduces spilling, slightly better thermal retention from reduced surface area.
Rocks
GlassOld Fashioned glass. Thick walls provide modest insulation. Low fill ratio — most volume is ice.
Highball
GlassTall, narrow. High fill ratio. Ice column keeps drink cold but dilution accumulates over longer service.
Collins
GlassTaller than highball. Same physics, more volume. Long drinks with extended service windows.
Copper Mug
CopperMoscow Mule standard. Copper's extreme conductivity chills the exterior instantly but also transfers ambient heat back in.
Tiki Mug
CeramicThick ceramic walls provide excellent insulation. Slowest ambient heat transfer of any vessel. Ideal for crushed ice drinks.
Martini
GlassWide V-shape maximizes surface area. Fastest warming of any up glass. Demands a well-chilled cocktail.
Thermal Warming Curves
Impact on Service
Tiki mug (ceramic, 5mm wall) holds crushed-ice drinks meaningfully longer than thin glass — up to ~50% in warm service.
Martini glass (thin glass, wide V). Up cocktails warm fastest here — serve ice cold.
Copper mug. Performance depends heavily on ambient temp and whether the mug was pre-chilled.
