Key ideas in The Barista Craft
- A baseline espresso recipe follows a 1:2 ratio of dry grounds in to liquid coffee out
- Target extraction time for this baseline ratio is roughly 25 to 30 seconds
- Brew ratio measures weight in grams on a scale, not liquid volume
- Water under pressure takes the path of least resistance through the coffee bed
- Unevenly spread dry grounds leave dense spots and thin spots, causing high-pressure water to tunnel channels
- Channeling produces a cup that tastes both harsh and sour because water over-extracts the channel while ignoring the rest
- Tamping only needs enough force to press the air out until the coffee bed fully resists
- A level, flat tamp is far more important than brute muscle to prevent lopsided water flow
- Tapping the portafilter or using extreme force can fracture the coffee puck and create bypass cracks
- The timer starts the moment the pump engages and pushes water into the coffee
- Water contacting the grounds begins extraction before liquid actually drips into the cup
- Total pump run time diagnoses whether your grind size allows water to flow at the right speed
- Under-extracted espresso tastes aggressively sour, sharp, and watery because fast water only pulls out early acids
- Over-extracted espresso tastes intensely bitter, harsh, and leaves an astringent, dry coating on the tongue
- A balanced, properly extracted shot carries sweetness and body that smooths out both acidity and bitterness
- Grinding finer packs the coffee particles closer together, slowing water flow and increasing flavor extraction
