Engineered for high-volume commercial bars and spirit-forward service, this Double Old Fashioned (DOF) rocks glass delivers the substantial weight, structural balance, and optical clarity required by professional beverage programs. The generous 13.5 oz capacity accommodates large-format ice cubes and handcrafted cocktails like Old Fashioneds without overcrowding, while the thick, weighted base anchors the glass securely to bar tops to prevent tipping during rapid service.

Structural Design & Functional Benefits
Weighted Base Architecture
Thick glass shiv distributes mass downward, lowering the center of gravity to prevent accidental spills on crowded bar counters.
Thermal Shock Resistance
Controlled cooling arches during production allow safe transition from ambient storage to chilled service without micro-fissures.
Rim Strengthening Profile
Fire-polished, laser-cut rim features a smooth, rounded edge that resists chipping from spoon impact and glass racks.
Ergonomic Wall Contour
Straight exterior walls provide a secure, slip-resistant grip for bartenders handling wet glassware during peak operating hours.
Commercial Applications
Craft Cocktail Bars
Optimized for spirit-heavy, stirred drinks served over 2-inch ice cubes or hand-carved ice spheres.
Hotel & Resort Dining
Durable construction withstands intensive multi-shift commercial dishwashing and high-frequency handling.
Spirits Brand Promotions
Provides a substantial canvas for custom-branded glassware sets bundled with premium whiskey releases.
Upscale Retail
Suitable for domestic kitchenware collections requiring heavy-weight commercial aesthetics.
Geometry & Glass Shape
Straight-Wall Alignment
Vertical walls allow aromas to concentrate below the rim while maintaining a wide opening for large ice insertion.
Proportional Taper
Subtle internal flare facilitates effortless stackability and rapid manual drying.
Base-to-Rim Ratio
A 1:1.1 aspect ratio ensures the glass appears balanced on tabletops, blending traditional proportions with modern durability requirements.
Beverage Compatibility
Whiskey & Bourbon
Accommodates neat pours, neat-on-the-rocks, and traditional Old Fashioned cocktails.
Stirred Cocktails
Ideal for Negronis, Sazeracs, and Boulevardiers served over solid ice.
Non-Alcoholic Service
Suitable for craft sodas, artisanal mocktails, and water service in fine dining settings.
Quality Control Standards
Visual Defect Inspection
Automated optical scanners and manual operators check every piece for bubbles, inclusions, surface streaks, and mold seams.
Dimensional Verification
Random sampling every 30 minutes measures rim diameter, wall thickness, and height against engineering blueprints.
Stress Analysis
Polariscope testing evaluates internal annealing quality to ensure uniform molecular stability and reduce spontaneous breakage risks.
Chemical Leach Testing
Periodic laboratory testing verifies compliance with international heavy metal migration limits for food-contact safety.
