Double-walled Glass Cup HARIO 370 ml for Matcha – Transparent

Double-walled Glass Cup HARIO 370 ml for Matcha – Transparent is a borosilicate glass cup engineered to serve matcha and other hot or cold beverages while reducing heat transfer and surface condensation. The transparent double-wall construction creates an insulating air layer that helps maintain beverage temperature and provides a clear view of preparation and froth. The cup is lightweight, dishwasher-safe under manufacturer guidelines, and designed for everyday use in homes, cafés, or tea bars where visual presentation and temperature retention are important.

Advantages

The double-walled borosilicate design provides effective thermal insulation without adding bulk, keeping hot drinks warm and cold drinks cool for longer compared with a single-walled glass. The transparent walls showcase the color and texture of matcha, layered drinks, or infusions, while minimizing external condensation on the outer surface. Borosilicate glass offers good mechanical and thermal shock resistance and a neutral non-reactive surface, preserving beverage taste. The cup’s shape and rim are optimized for comfortable sipping and clear presentation.

Suitable for

• Preparing and serving matcha, cappuccinos, lattes, and other tea-based beverages
• Serving hot or cold specialty drinks in cafés and tea bars
• Home use for everyday tea and coffee consumption
• Demonstrating layered drinks or froth during preparation

How to use

Rinse the cup before first use. Pour prepared matcha or other beverage directly into the cup up to a comfortable fill level, taking care to leave space for foam if applicable. Handle by the outer wall or base to avoid hot contact with the inner surface. After use, allow the cup to cool before cleaning. Follow manufacturer care instructions if using a dishwasher, and avoid rapid temperature changes such as pouring boiling water into a frozen or very cold cup.

Usage recommendations

For best results with matcha, pre-warm the cup with a small amount of hot water and discard it before pouring the prepared matcha; this helps stabilize temperature and prolongs warmth. When serving cold beverages, adding a few ice cubes shortly before serving preserves clarity and presentation. Handle borosilicate glass carefully to avoid impacts and follow washing instructions to maintain transparency and longevity.
