Tuni E2 Gen3 Espresso Machine with G3 64mm Flat Burr Grinder - 20Bar ULKA Pump, Super+ Steam, PID Temp Control, 100 Settings, Anti-Static, Stainless Steel

Product Overview

The E2 Gen3 combines a commercial-grade 58mm brew head with a dual boiler system that allows simultaneous brewing and steaming, eliminating the wait time between pulling a shot and frothing milk. The G3 grinder uses 64mm stainless steel flat burrs, which provide a wide grinding surface for uniform particle size and low heat retention, preserving the beans' volatile aromas. The stepless adjustment ring offers 100 grind settings, ranging from fine espresso to coarse French press, giving you precise control over extraction. A PID controller paired with NTC sensors maintains water temperature within a tight window, while the visible pressure gauge lets you monitor the 20-bar pump's performance in real time. The machine also supports cold brewing: simply add ice water to the tank to brew cold coffee in minutes. The touchscreen interface offers single, double, and continuous grinding modes with 0.5-second increments. Dual bean hoppers—a 250g main and 50g secondary—let you switch between different beans or decaf without emptying the entire hopper. Anti-static technology reduces static cling, minimizing mess during grinding. The stainless steel body and modern design fit most countertops, though the 13-pound weight and 12.9-by-7.4-by-13.2-inch footprint require dedicated space. Daily cleaning is straightforward: brush the grinding housing, upper burr, and powder outlet after each use. The manufacturer recommends using only soft brushes to avoid damaging components. While the package includes both the espresso machine and grinder, they ship separately, so expect two boxes.

Build & Materials

The E2 Gen3 is built around a stainless steel chassis that gives it a sleek, modern appearance and durable feel. The 58mm brew head is made of brass and chrome-plated for corrosion resistance and thermal stability. The G3 grinder housing is also stainless steel, matched to the machine's silver finish. The dual bean hoppers are BPA-free plastic with airtight lids to preserve freshness. The touchscreen interface is responsive and easy to navigate, with clearly labeled icons. The water tank is removable and has a 2.8-pound capacity, which corresponds to roughly 1.3 liters. The steam wand is a single-hole, commercial-style design that produces dry steam for microfoam. The machine's footprint is relatively compact for its capabilities, but it requires about 13 inches of depth and 7.5 inches of width, plus clearance for the grinder and steam wand. Weight is 13 pounds, making it stable but not easily portable.

Daily cleaning involves brushing the grinding housing, upper burr, and powder outlet after each use. The manufacturer advises against using wet cloths on electrical parts. The drip tray is large and easy to remove for rinsing. The included tamper is plastic but functional. Overall, the build quality feels substantial for the price, though some internal components (like the pump) are not user-serviceable.

Shot Quality

The dual boiler system and PID control work together to deliver stable water temperature throughout the extraction. The 20-bar pump ensures sufficient pressure, and the visible gauge helps you confirm you're in the ideal range (typically 9-10 bars). The 58mm brew head promotes even water distribution, which, combined with precise grind size from the 64mm burrs, produces consistent shots with thick crema. The stepless grind adjustment lets you fine-tune for different beans, but there is a learning curve to dialing in. The anti-static technology keeps grounds from scattering, ensuring the dose you set is the dose you get.

Steam performance is a standout: the dedicated boiler produces powerful, dry steam that textures milk quickly and evenly. The single-hole wand is forgiving for beginners yet capable of creating silky microfoam for latte art. Hot and cold brew functions work as advertised—cold brew takes about five minutes with ice water. The machine does not overheat during extended use, thanks to the dual boiler design. One trade-off is that the 13-pound weight makes it less portable, and the grinder does add counter space. Without third-party reviews, these assessments are based on manufacturer claims and design specifications.
