Drink-Specific Guidelines
| Drink | Milk Amount | Texture | Notes |
|---|---|---|---|
| Espresso | None | N/A | Serve immediately |
| Americano | Add hot water 5:1 | N/A | Add water to shot |
| Cappuccino | 4:1 milk:espresso | Thick, velvety | Equal parts foam/liquid |
| Latte | 6:1 milk:espresso | Silky, minimal foam | Thin layer of microfoam |
| Macchiato | 1:1 milk:espresso | Stiff foam | Just a "mark" of foam |
Troubleshooting Your Shots
| Problem | Likely Cause | Solution |
|---|---|---|
| Bitter taste | Over-extraction | Coarsen grind or reduce yield |
| Sour taste | Under-extraction | Finer grind or increase yield |
| Fast shot | Grind too coarse | Adjust grind finer |
| Slow shot | Grind too fine | Adjust grind coarser |
| Channeling | Poor distribution | Improve distribution technique |
Pro Tips for Espresso Excellence
- Temperature management: Each machine is different, learn your machine's ideal temperature
- Dose consistency: Use a scale for precise dosing every time
- Fresh beans: Use beans within 2-4 weeks of roast date
- Clean equipment: Backflush daily and keep your workspace clean
- Grinder maintenance: Clean burrs regularly and calibrate as needed
Customize Your Experience: While the calculator provides excellent starting points, espresso is both art and science. Use these measurements as a foundation, then adjust to your taste preferences and the specific coffee you're using. Remember that different coffees may require slightly different parameters for optimal extraction.
