Dialing In Pure Earth SUMMIT Espresso: The Step-by-Step Guide to Perfect Shots
Start With the Right Variables
Four primary variables: dose, yield, time, and temperature. For SUMMIT: 18g dose, 36-40g yield, 27-32 seconds, 91-93C. These are your starting point -- your grinder, machine, and water will require fine-tuning from here.
The Dial-In Sequence
- Step 1: Lock in your dose at 18g. Weigh it every time.
- Step 2: Pull your first shot. Time it and weigh the yield.
- Step 3: Too fast (under 22 sec)? Grind finer. Too slow (over 35 sec)? Grind coarser. Adjust in small increments.
- Step 4: Once at 27-32 seconds, taste. Sour = under-extracted. Bitter = over-extracted.
- Step 5: Lock in the grind setting once balanced. Log it.
SUMMIT-Specific Notes
SUMMIT is a medium roast blend that extracts best at 91-93C -- slightly higher than dark roast espresso. It benefits from a slightly longer yield (38-40g) where caramel sweetness fully develops. If shots taste flat or thin, lengthen the yield before adjusting grind.
Milk Drinks
Do not reduce your dose -- 18g is the right foundation. Steam milk to 60-65C for maximum sweetness. SUMMIT's chocolate and caramel notes are designed to cut through milk cleanly.
Dialing in is not a one-time event. It is a daily check-in. Grinder burrs, humidity, and bag age all shift parameters slightly. Good espresso is a practice, not a setting. -- PURE EARTH COFFEE
When Shots Are Inconsistent
Inconsistency usually comes from dose variation (fix with a scale), distribution issues (fix with a WDT tool), or grinder retention (purge 2-3g before each dose). SUMMIT rewards consistent preparation -- when inputs are consistent, outputs are too.
Key Takeaways
- SUMMIT target recipe: 18g dose, 36-40g yield, 27-32 seconds, 91-93C -- start here and adjust one variable at a time
- Always change one variable at a time when dialing in -- changing multiple simultaneously loses the signal
- SUMMIT benefits from a slightly longer yield (38-40g) where caramel sweetness fully develops
- Shot inconsistency usually comes from dose variation, distribution problems, or grinder retention
- Use a WDT tool to break up puck clumps -- high-impact low-cost espresso upgrade
