Tea infuser glass bottle Ofenbach 480 ml model 100617S, borosilicate drinking bottle with built-in infuser

The Ofenbach tea infuser glass bottle model 100617S is a 480 ml borosilicate drinking bottle with a built-in infuser designed for brewing loose-leaf tea, herbal blends and fruit infusions while on the move. The borosilicate glass body resists thermal shock and preserves the flavour of beverages without imparting odours. The integrated infuser/filter enables steeping directly in the bottle and separates leaves or solids from the poured liquid for a cleaner drinking experience. The compact cylindrical shape and secure lid make the bottle suitable for everyday carry, commute, office use and light travel.

Advantages

The borosilicate glass construction ensures chemical neutrality and temperature resistance, maintaining beverage taste and clarity. The built-in infuser allows convenient brewing without additional equipment and helps control infusion strength by removing the filter when steeping is complete. The 480 ml capacity balances sufficient volume with portability for single-serve use. The design minimizes contact between liquid and external materials, and the secure closing mechanism reduces risk of spills during transport.

Suitable for

• Brewing loose-leaf tea and herbal infusions on the go
• Cold-brew fruit or tea infusions
• Office, commuting and light travel use
• Single-serve hot or cold beverages where taste purity is important

How to use

Remove the lid and add the desired amount of loose tea, herbs or fruit pieces into the built-in infuser. Pour hot or cold water into the bottle, secure the lid and allow the contents to steep for the recommended time for your chosen infusion. When steeping is complete, lift or remove the infuser according to the product mechanism to separate leaves from the liquid, then drink directly from the bottle. After use, disassemble the lid and infuser and rinse all parts with warm water; wash thoroughly when necessary to remove residue.

Usage recommendations

For best results with hot beverages, pre-warm the glass by rinsing with warm water before adding boiling water. Avoid rapid temperature changes to prolong the life of the borosilicate glass. Clean the infuser after each use to prevent buildup of residue and to maintain neutral taste.
