Glass Tea Infuser Mug Vialli Design Bolla with Built-in Strainer 400 ml

Vialli Design Bolla is a 400 ml glass tea infuser mug with a built-in strainer, designed for brewing loose-leaf tea and herbal infusions. The transparent borosilicate-style glass body allows visual control of the steeping process and enables serving directly from the mug. The integrated fine-mesh filter holds tea leaves while allowing clear, balanced tea to pour into the cup, combining brewing and serving in one compact vessel suitable for single-serve preparation.

Advantages

The glass construction provides neutral taste and thermal stability, so aromas remain unaltered and the mug resists rapid temperature changes. The built-in strainer simplifies preparation by containing leaves inside the mug during infusion and allowing drip-free pouring. The 400 ml capacity is suitable for generous single servings or small shared portions, and the transparent design helps achieve consistent steeping times. The mug is lightweight and easy to clean compared with multi-part teapots and separate strainers.

Suitable for

• Brewing loose-leaf black, green, white or herbal teas
• Preparing single-serve infusions at home or at the office
• Serving guests in small cafés, B&Bs or hotel rooms
• Monitoring steeping strength visually to obtain desired flavor

Key specifications

• Material: transparent heat-resistant glass
• Capacity: 400 ml
• Integrated fine-mesh strainer for loose leaves
• Designed for single-serve brewing and direct pouring
• Compact footprint suitable for kitchen counters and desks

How to use

Place the desired amount of loose-leaf tea into the built-in strainer, pour hot water at the appropriate temperature for the tea type, and let steep for the recommended time. Once brewing is complete, lift the filter or tilt the mug to pour; the integrated strainer retains leaves while liquid flows through for a clear cup. After use, discard the spent leaves and rinse the mug and filter with warm water; for deeper cleaning, wash with mild detergent and dry before storing.

Usage recommendations

To preserve flavor and glass clarity, avoid sudden extreme temperature changes—pre-warm the mug with hot water before adding boiling water. Use the visual transparency to time steeping precisely for delicate teas, and rinse promptly after use to prevent residue buildup.
