My Coffee Tastes Bitter or Sour

If the espresso you’re brewing with your Profitec Pro 300 is bitter or sour, you may need some more practice with pulling shots. The information below offers some great advice for new home baristas.

Typically, issues with crema or the flavor of the shot do not indicate a malfunction of the machine. Instead, this indicates that an adjustment needs to be made in the brewing process or that different beans need to be used.

  • Here is some helpful advice on Tamping.
  • Making adjustments to the grind is going to have the biggest impact on the coffee extraction. If it is too coarse, the coffee is going to come through too fast, and not extract long enough.
  • If the grind is too fine, it is going to extract for too long, resulting in really bitter shots.
  • It is important to use fresh beans, typically beans roasted within the past two weeks are best. Light and medium roasts are best for espresso brewing and producing richer crema.
