What you'll learn

Key ideas in Espresso by Taste and Roast

  • Espresso extracts acids and sharp sour notes first
  • Sugars extract mid-shot to create balanced sweetness
  • Heavy bitter and astringent compounds wash out last
  • A standard beginner baseline espresso ratio is 1:2 (coffee dose to liquid yield)
  • Dosing 18 grams of dry coffee yields roughly 36 grams of liquid espresso in the cup
  • The 1:2 ratio balances heavy body with clear flavor separation
  • Espresso naturally separates into dense, bitter crema on top and sweeter, syrupy liquid underneath
  • Taking a sip without stirring means your first impression is dominated by bitter foam
  • Stirring integrates the distinct layers into a single cohesive sip
  • Sourness triggers immediate mouth-watering salivation and a puckering feel along tongue edges
  • Bitterness creates a lingering, drying astringency toward the back of the throat
  • Recognizing tongue and throat sensations tells you whether a shot pulled too fast or too slow
  • Sourness in espresso comes out first and signals under-extraction
  • Letting more water brew through the coffee puck extracts sweet sugars to balance the sharp acids
  • Ending a shot too early cuts off the extraction before sugars can dissolve
  • A harsh, drying bitterness indicates too much material was extracted from the coffee puck
