Shelbru June Dripper

The Shelbru June is a stainless steel pour over dripper built around one idea: hold brewing temperature steady from the bloom to your final pour. All drippers cool during the brew. As the slurry temperature drops, extraction slows and the balance of acidity, sweetness and bitterness shifts, some more so than others. Different materials and designs play a role in the thermal stability of your dripper and the June Dripper from Shelbru uses a double wall vacuum insulated body to slow that heat loss, giving you a more stable brewing environment and a more repeatable cup. Four Layered Design Shelbru describes June as a four layer construction. Each layer has a specific purpose rather than being there for looks: PVD outer coating: a fingerprint resistant matte finish that keeps the exterior looking clean in daily use. SUS304 double wall stainless steel body: the structural shell, and the part that carries the vacuum insulation. Vacuum insulated cavity: slows heat transfer out of the brew chamber, keeping slurry temperature more stable through the drawdown. Ceramic coated inner wall: the only surface your coffee touches, so there's no metallic or plastic character carried into the cup. Thermal stability Shelbru tested their June Dripper alongside other popular drippers (Glass and Metal) under identical immersion brewing conditions and reported that the June Dripper held a noticeably more stable temperature curve, while the comparison drippers showed larger fluctuations across the brew. In practical terms, that stability does two things, For everyday brewing it tends to bring out brighter acidity, more sweetness and a fuller body, a rounder and more structured cup without changing your recipe. For dialling in, it makes every other variable easier to read. When temperature isn't drifting underneath you, a change in grind size or pour rate shows up clearly instead of being masked. 12 concave ribs for even extraction The June Drippers brew chamber utilises twelve concave ribs rather than the raised ribs found on other conical drippers. The concave profile holds the filter paper flush against the dripper wall, which does two useful things. First, it reduces sagging and wrinkling in the filter. A filter that sits properly against the wall minimises bypass so more of your brew water actually hits the coffee bed and extracts your coffee. Second, the recessed channels between the ribs give air somewhere to escape as the bed saturates. Air escaping smoothly instead of burping through the bed means a more stable flow rate and a more even extraction across the whole drawdown. June Dripper's Ceramic Coated Inner Wall The interior is ceramic coated so brewed coffee never contacts bare metal. This is a small detail with a real effect: it prevents the faint metallic or plastic note that some stainless and plastic drippers can contribute, letting subtle origin character come through unmasked. It also makes the interior easy to rinse clean. Cool To Touch Because the outer wall is separated from the brew chamber by the vacuum layer, the exterior stays cool enough to handle comfortably during and after brewing. You can lift June off the carafe as soon as the drawdown finishes without reaching for a cloth. Aroma Flow™ Base June sits on a detachable silicone base Shelbru calls Aroma Flow™. It centres and stabilises the outflow so coffee lands where you want it rather than running down the side of the cone, and by concentrating that stream it is said to support a more structured aroma development and a sweeter perceived cup.
