The Stündenglass Glass Upstems (Small) provide an aesthetic and functional upgrade for users of the Stündenglass Gravity Infuser ecosystem. Moving away from standard aluminum components, these upstems are crafted from premium borosilicate glass to deliver a highly transparent and interactive visual experience. Designed for those who appreciate pure flavor, the glass material ensures an inert pathway that prevents any metallic taste from altering the vapor. Scaled specifically for the 470ml small globes, these upstems cater to users looking to optimize their Kompact units or modify their full-sized infusers. The clear design allows for an unobstructed view of the water filtration process in action.
Clear Visual Experience
The 100% transparent design of these upstems allows users to clearly watch the vapor travel up, down, and out of the percolator slits. This elevates the visual aspect that gravity infusers are known for. Made from hand-blown glass, the upstems provide an unobstructed view of percolation during each rotation, adding a highly interactive element to the standard water filtration process.
Pure Flavor Preservation
Constructed from premium borosilicate glass, these upstems offer a completely inert pathway for the draw. Unlike standard metal parts, the glass material will not leech any metallic tastes into the pull, preserving the pure flavor profile of the material used. Additionally, the upstems feature built-in diffusion slits at the base to ensure a remarkably smooth, well-filtered pull.
Precise Device Compatibility
Each upstem features a precisely threaded base that securely screws directly into the main body of compatible Stündenglass units, creating an airtight seal. They are exclusively compatible with the Kompact Gravity Infuser and full-size V2 or V3 models equipped with 470ml Small Glass Globes or Pineapple Globes. They are completely incompatible with V1 units or large 700ml glass globes.
Straightforward Cleaning Requirements
To maintain the structural integrity and warranty of the upstems, specific care guidelines must be followed. The manufacturer recommends soaking the pieces exclusively in isopropyl alcohol before thoroughly flushing them with clean water. These glass components are explicitly marked as not dishwasher safe, meaning hand-cleaning is required to prevent accidental damage to the delicate percolation slits and threads.
