## What is Act Four?

Let’s brew amazing espresso.

New to espresso? Act Four’s video-guided workflow is designed to quickly walk you through the same steps used by professional baristas. We’ll analyze the speed and taste of each brew to tweak your machine, grinder, and brew recipe until you land on your ideal cup.

Espresso pro? Let’s dial in by taste. After each brew, we’ll dive into the tasting experience to drive adjustments to Brew Weight and Brew Timing. Each brew iterates on the previous until we hit that magic cup. Act Four’s minimal workflow is designed to be hands-free and out of your way. Just open the app for automatic recipe, preinfusion, brew, and flow rate tracking.
