The right glass doesn't just hold wine; it elevates it. As a premier supplier of premium stem wine glasses, KINGSTAR GLASSWARE provides the professional-grade tools that sommeliers, restaurateurs, and wineries demand. Our glasses are crafted from brilliant, lead-free crystal, designed not only for beauty but for performance. Each element, from the shape of the bowl to the fineness of the rim, is engineered to enhance the wine's aroma, flavor, and overall profile, delivering a superior sensory experience.
What makes lead-free crystal superior for a premium wine glass?
Lead-free crystal offers the best of all worlds. It provides the exceptional clarity, high refractive index (sparkle), and satisfying resonance of traditional leaded crystal, but is lighter, more durable, and completely inert, ensuring nothing interferes with the wine's delicate chemistry. This makes it the modern standard for fine dining glassware and the choice of professionals who prioritize both elegance and purity.
How does the shape of the glass affect the taste of the wine?
The shape is critical. A large, wide bowl (like in our Burgundy glass) captures the delicate aromas of wines like Pinot Noir. A taller, more tapered bowl (like our Bordeaux glass) directs the aromas of powerful, full-bodied wines like Cabernet Sauvignon towards the nose. The ultra-fine, laser-cut rim delivers the wine smoothly onto the palate without disrupting its texture. As an expert manufacturer, we produce varietal-specific shapes that are true to their purpose.
What are your MOQ and OEM options for branding?
We offer competitive, factory-direct pricing for our premium stemware. For our lead-free crystal glasses, the Minimum Order Quantity (MOQ) typically starts around 1,000 to 3,000 units per shape. As a sophisticated OEM partner, we offer discreet and elegant branding options, such as laser-etching a restaurant logo or winery emblem onto the foot of the glass. This provides a subtle, high-end branding touch perfect for sommelier-grade barware.
Choosing KINGSTAR GLASSWARE means sourcing world-class stemware from a supplier that understands the art and science of wine.

FAQ
Q1: Why is there a small "dot" at the bottom of the double-wall cup?
This is a critical safety feature known as the ventilation point. During the hand-blowing process, this vent allows the air pressure between the glass layers to equalize when hot or cold liquids are added. It is sealed with a specialized silicone plug to maintain the vacuum and prevent the glass from shattering during rapid temperature changes.
Q2: Can these double-wall cups be used for hot stovetop heating?
While the borosilicate glass itself is heat-resistant, double-wall cups are designed for service and storage rather than direct stovetop boiling. The vacuum layer is optimized for temperature retention. For direct heating, we recommend our KINGSTAR Single-Wall Borosilicate Pitchers.
Q3: Do you provide custom gift box packaging for retail brands?
Absolutely. We specialize in "shelf-ready" packaging for B2B partners. We can design and produce custom-printed color boxes, including protective foam or eco-friendly cardboard inserts, to ensure safe transit and a premium unboxing experience for your customers.
