GRAV® Upline® Taster – Black Label: The Architectural Classic Among One-Hitters

Compact, cool, and unmistakable. The GRAV Upline® Taster is far more than just a simple glass chillum. It is a technical masterpiece in pocket format. Thanks to the iconic Upline design with its distinctive lamellae, this taster offers a performance typically only found in large glass pipes – and all this at a handy length of 10 cm.

Why the Upline Taster will be your new favorite piece:

• Innovative Cooling System: The characteristic "Upline rings" are not just decorative. They serve as expansion chambers that swirl the airflow, cool the smoke, and simultaneously act as an effective ash catcher.
• Solid Borosilicate Glass: Made from high-quality 16mm glass tubing, this taster feels significantly heavier and more premium in hand than conventional one-hitters.
• Ergonomic Mouthpiece: The tapering opening ensures comfortable lip contact and precise control during inhalation.
• Black Label Elegance: The subtle black GRAV logo gives the clear glass a minimalist, sophisticated look.

FAQ – Everything You Need to Know

What makes the Upline design so special?

The constrictions in the glass force the smoke through multiple chambers. This increases the surface area where the smoke can cool and reliably prevents particles or ash from entering the mouth.

What's the best way to clean the Upline Taster?

Thanks to the straight passage, cleaning is effortless. A quick soak in isopropanol or a special resin cleaner will make the clear glass look like new again in just a few minutes.

Is the taster also safe for travel?

Yes! The 16mm thick walls make it significantly more robust than standard glass pipes. It fits perfectly in any pocket or small case.

Can I combine the taster with a vaporizer?

Indeed, many fans use the Upline Taster as an alternative mouthpiece (stem) for vaporizers like the Tinymight 2, as it cools the vapor excellently.
