ACS Vostok

The Vostok uses the lever to control the water flow and pressure profile through the coffee puck, while the dual-boiler system ensures the water entering the group head is held at a precise, PID-controlled temperature. This setup gives you the tactile, hands-on experience of a traditional lever machine without sacrificing the thermal stability required for modern, light-roast espresso.

This is a manual machine designed for enthusiasts who want to actively participate in the brewing process. While the PID temperature control makes it more forgiving than a vintage lever machine, the pressure profiling and manual lever operation require a learning curve and a good understanding of espresso extraction variables.

You have full manual control over the extraction process. By operating the lever, you can manipulate the pressure throughout the shot, allowing you to experiment with different flow rates, pre-infusion times, and pressure curves to highlight specific flavor notes in your coffee.

Yes, because the machine features a dedicated steam boiler, you have consistent, high-pressure steam available whenever you need it. The manual wand allows for the precise control necessary to create the microfoam texture required for latte art.

Maintenance is straightforward but requires consistency. You will need to regularly backflush the group head, keep the steam wand clean, and monitor the condition of the seals within the lever group, which may need periodic replacement depending on your usage frequency.

Yes, the Vostok allows you to customize pre-infusion pressure and duration. This is a critical feature for dialing in modern, lighter-roasted beans, as it lets you gently saturate the coffee puck before applying full extraction pressure to prevent channeling.
