Understand the lineup

Espresso Series 1 brings guided recipes and adjustable pressure profiles to a separate-machine setup. Its temperature-sensing steam wand assists milk temperature, while grinding and puck preparation remain separate tasks. Opus Gen 2 is the grinder record in this library.

Where to start

Do not read the Series 1’s Boosted Boiler label as shorthand for a conventional dual boiler: the documented design combines a single boiler with additional heaters. On Opus, confirm the Gen 2 version rather than transferring adjustment details from the earlier generation.

Editorial interpretation of the linked product documentation. Individual profiles retain their source-check dates and configuration notes.
