  5. Rinse Thoroughly: Get rid of any detergent or cleaner residue by rinsing the portafilter thoroughly under hot running water.

  3. Technique Matters: Make sure you’re tamping level. If your tamper is at an angle, you’ll get uneven extraction, and the water will find the path of least resistance. That’s a surefire way to a wonky espresso shot.
  4. Don’t Overthink It: Too much pressure and you’ll compact the grounds too much, leading to over-extraction. careful with your coffee density. Too little, and you’ll have a watery, under-extracted mess. Find that Goldilocks zone and practice, practice, practice.
  5. Consider a Calibrated Tamper: If you’re worried about tamping technique consistency, a calibrated tamper takes the guesswork out of the equation. It’s set to apply the same pressure every time, kind of like a trusty meat thermometer ensuring your BBQ is cooked to perfection.
  6. Feel the Grounds: Lastly, get to know your coffee. The grind size, freshness, and even the type of coffee can influence how it should be tamped. Don’t be afraid to experiment and find what works best for you, develop your tamping skills like crafting that perfect bourbon cocktail.
