Common Questions
Why should I use a burr grinder instead of a blade grinder?
Burr grinders produce uniform particle sizes, which means even extraction and balanced flavor. Blade grinders chop randomly, creating a mix of dust and boulders that leads to simultaneous over-extraction (bitterness) and under-extraction (sourness). Even a $50 burr grinder like the Baratza Encore dramatically improves cup quality over any blade grinder.
What coffee equipment should a beginner buy first?
Start with three things: a burr grinder ($50-100), a pour-over dripper like the Hario V60 or Kalita Wave ($25-35), and a kitchen scale ($15-20). This setup costs under $150 and produces coffee that rivals $5 cafe drinks. Add a gooseneck kettle later for better pour control. Skip espresso until you understand extraction basics.
How much should I spend on my first espresso machine?
Under $300 gets you pressurized portafilter machines (Breville Bambino, De'Longhi Stilosa) that are forgiving but limit growth. The $400-700 sweet spot (Breville Barista Express, Gaggia Classic Pro) offers unpressurized baskets, PID temperature control, and the ability to dial in real espresso. Spending under $200 on an espresso machine usually leads to disappointment.
What is the ideal coffee-to-water ratio?
The standard starting ratio is 1:16 (1 gram of coffee per 16 grams of water). For stronger coffee, try 1:14; for lighter, 1:17. For espresso, the standard is 1:2 (18g in, 36g out in 25-30 seconds). Always measure by weight, not volume — a tablespoon of dark roast weighs less than light roast due to moisture loss during roasting.
Key Terms
Extraction Yield
The percentage of coffee solubles dissolved during brewing. Measured with a refractometer. Target: 18-22% for most brew methods. Below 18% = under-extracted (sour, underdeveloped). Above 22% = over-extracted (bitter, astringent). The single most important variable in coffee quality.
Total Dissolved Solids (TDS)
The concentration of dissolved coffee compounds in the brewed cup, measured as a percentage. Filter coffee target: 1.15-1.35% TDS. Espresso target: 8-12% TDS. TDS × brew ratio = extraction yield. Higher TDS means stronger (more concentrated) coffee, which is independent of extraction quality.
Grind Size
The coarseness or fineness of ground coffee particles. Finer grinds increase extraction rate (more surface area). Espresso: fine (powdery). Pour-over: medium. French press: coarse. Dialing in the correct grind is the single most impactful variable after coffee freshness. Always adjust grind before other parameters.
Burr Grinder
A grinder using two abrasive surfaces (burrs) to crush coffee beans to a uniform particle size. Flat burrs produce more uniform particles; conical burrs are quieter and produce less heat. Always preferred over blade grinders for coffee quality. Entry-level: $50-100 (Baratza Encore). Premium: $200-2000+.
Grind Retention
The amount of ground coffee that remains inside a grinder between uses, measured in grams. High retention (2-5g) wastes coffee and means stale grounds contaminate fresh doses. Single-dose grinders (Niche Zero, DF64) are designed for near-zero retention. Purging 2-3g helps flush retained grounds.
