A tool for espresso lovers, by espresso lovers.
Dial Your Shot is a free, browser-based espresso brewing guide that helps you improve your espresso, one shot at a time. You enter your dose, yield, grind size, extraction time, temperature, pressure, and then rate how the final shot actually tastes. The app uses those inputs to suggest practical adjustments, hints, and next-step recommendations to help you make the next shot better.
Whether you're just getting started with espresso or you've been dialing in shots for years, our goal is simple: give you a helpful starting point, a clearer diagnosis, and useful guidance for moving closer to that elusive sweet spot.
We're passionate about coffee, but we're also humble about what we know. The algorithm behind Dial Your Shot was built by carefully studying a wide range of trusted sources, including specialty coffee research, barista community knowledge, and extraction science. We've tried to turn that into something practical, accessible, and useful in the moment when you're trying to understand why a shot tasted the way it did.
That said, espresso is complex, and every machine, grinder, bean, and environment is different. Our model is a guide, not a guarantee. It does not try to tell you exactly how a shot should taste in theory; it reacts to the taste result you report and suggests where to adjust next. We're continuously working to improve the algorithm, and we actively seek feedback from more experienced people, professional baristas, roasters, and dedicated home brewers to make sure the recommendations stay grounded in reality.
You can optionally sign in with your Google account to save espresso presets to our servers. A preset captures your full parameter setup — dose, yield, extraction time, temperature, pressure, pre-infusion, roast level, bean freshness, grind distribution, and grind size — so you can return to a known-good configuration or compare setups across sessions.
Signing in requires only your email address and basic Google profile information. We request no other permissions. You can delete your account and all saved presets at any time from your Profile page. See our Privacy Policy for full details on what is stored and how.
This is an evolving project. We know there's still a lot to improve: from the accuracy of the recommendations to the way we explain the suggestions. We believe in being transparent about that. If something feels off or you have a better way to think about a particular variable, we'd genuinely love to hear from you.
Dial Your Shot was created by PiroTechnique, a coffee enthusiast who wanted a clean, distraction-free tool for improving espresso without having to dig through forum threads every morning.
It's free. The core tool works without an account. When you sign in to save presets, we store only what is necessary to make that feature work — nothing more.
