Engineered for crisp, high-acidity white wines such as Sauvignon Blanc, Riesling, and Pinot Grigio, this narrow bowl white wine glass features a tapered rim that controls ethanol vapor release while focusing delicate citrus and floral aromatics. Formed from lead-free titanium crystal glass through automated press-blow and drawn-stem processes, each unit delivers uniform wall thickness, high impact resistance, and durability against repeated commercial dishwasher cycles.

Performance Features
Monobloc Stem Integration
Continuous drawn-stem manufacturing removes joint stress points between bowl and base, increasing resistance to lateral snapping during wiping or washing.
High Optical Clarity
Refractive index of 1.52 with over 91% light transmission allows accurate visual assessment of wine hue and viscosity.
Corrosion Resistance
Chemical glass composition resists surface etching and clouding caused by harsh industrial wash chemicals.
Commercial Applications
Hotels, Restaurants & Catering (HoReCa)
Physical dimensions fit standard 25-compartment commercial glass racks to lower handling damage in high-volume operations.
Wineries & Tasting Rooms
Tapered opening provides a uniform platform for controlled wine sensory evaluation and standardized sample pours.
Retail & Corporate Promotion
Smooth sidewalls accept direct brand customization, while outer packaging options pass strict transit drop tests.
Narrow Bowl Functional Engineering
Temperature Stability
Compact surface area reduces ambient heat transfer, keeping chilled wines within target serving ranges (8°C–12°C) longer than wide bowls.
Aroma Concentration
Tapered top opening curtails harsh alcohol vapor while directing delicate volatile compounds toward the nose.
Palate Direction
Angle of the inner wall directs liquid flow to the center of the tongue to balance crisp acidity with natural fruit sweetness.
Varietal Wine Compatibility
Sauvignon Blanc & Herbal Blends
Directs crisp citrus and botanical aromas upward without dispersing light volatile top notes.
Riesling (Dry & Off-Dry)
Concentrates subtle stone fruit notes while softening sharp acidity on the palate.
Pinot Grigio / Pinot Gris
Preserves subtle mineral tones and maintains a fresh finish.
Unoaked Chardonnay & Chablis
Highlights fresh fruit minerality without exposing the wine to excessive aeration.
Rim & Stem Ergonomics
Laser-Cut Rim Processing
Cold-laser cutting removes thick rolled edges for direct wine delivery from glass to palate.
Drawn Stem Geometry
Smooth vertical stem pulled from molten glass increases tensile strength against twisting force during hand polishing.
Flat Base Alignment
Base geometry finished within 0.2 mm plane tolerance ensures stable placement on wet stone or wood tables.
Advanced Manufacturing Quality Control
Automated IS Press-Blow Production
Computerized forming systems maintain glass wall thickness consistency within ±0.2 mm across large production runs.
Annealing Lehr Stress Relief
Controlled 45-minute multi-zone cooling process removes internal thermal stresses within the glass structure.
Automated Vision Inspection
High-speed optoelectronic cameras check 100% of production for inclusions, rim micro-cracks, and dimensional variance.
