• incorrect grind (too coarse)
• insufficient amount of coffee in group handle
• tamp was incorrect
• ground coffee was left to sit in dosage chamber for a long period of time
• incorrectly adjusted machine

You can tell a shot is under extracted if :

• the crema appears thin, light in colour and bubbly
• cake is sloppy
• tastes sour
