Common Questions
How much does water quality affect coffee taste?
Enormously — coffee is 98% water. Hard water mutes acidity and produces flat flavors. Too-soft water over-extracts and tastes sharp. Ideal brewing water has 50-175 ppm total dissolved solids, a pH of 6.5-7.5, and no chlorine. If your tap water tastes bad, your coffee will too. Third Wave Water mineral packets or a simple Brita filter make a noticeable difference.
Does dark roast have more caffeine than light roast?
No — it's a myth. Measured by weight (scoops), light roast has slightly more caffeine because the beans are denser. Measured by volume, dark roast may have marginally more because the beans are larger and you fit fewer in a scoop. The difference is negligible either way (less than 5%). Brewing method and coffee-to-water ratio affect caffeine far more than roast level.
What is the difference between a heat exchanger and dual boiler espresso machine?
A heat exchanger (HX) machine has one boiler for steam, and a copper tube running through it heats water for brewing — allowing simultaneous steaming and brewing but with less precise brew temperature control. A dual boiler has separate boilers for steam and brewing, offering independent temperature control for both. Dual boilers are more expensive but produce more consistent shot temperatures, making them preferred by serious home baristas.
What is ideal water TDS for espresso?
The Specialty Coffee Association recommends 75–150 mg/L (ppm) TDS for brewing water, with 150 ppm being the sweet spot many home baristas target. Water with TDS under 50 ppm (like most distilled water) is too soft and corrosive. Water over 200–250 ppm causes rapid scale buildup. You can measure TDS with a cheap TDS meter ($10–$15 on Amazon) and adjust by mixing tap water with distilled water to hit your target range.
Is pour over coffee better or worse than espresso?
Neither is objectively better — they're different. Pour over (V60, Chemex, Kalita Wave) produces a clean, bright, nuanced cup that highlights a coffee's origin characteristics. Espresso is concentrated, intense, and showcases the roast character. Specialty coffee enthusiasts often prefer pour over for light-roast single origins and espresso for darker roasts or milk drinks. The "better" one is whichever brewing method you prefer for the occasion.
What are the basics of French press coffee?
French press uses full immersion brewing — coarsely ground coffee steeps in hot water for 4 minutes, then a metal mesh plunger separates grounds from liquid. The lack of paper filter means coffee oils pass through, creating a fuller body compared to pour over. Key tips: use a coarse grind (crumbled-cracker texture), water at 93–96°C (200–205°F), stir at 1 minute, plunge gently at 4 minutes, and pour immediately to avoid over-extraction.
What is puck prep for espresso?
Puck prep is the process of preparing the coffee grounds in the portafilter before brewing: distributing the grounds evenly, removing clumps (using a WDT tool), and tamping with consistent pressure. Good puck prep is essential for even extraction — an uneven puck channels water unevenly. A typical routine: dose into basket, run WDT tool through grounds, level/distribute, tamp with 15–20kg of pressure, then lock into the machine.
What temperature should espresso be brewed at?
The SCA recommends 90–96°C (195–205°F) for espresso brewing. Lighter roasts benefit from higher temperatures (94–96°C) to extract more sweetness; darker roasts do well at lower temperatures (88–92°C) to avoid over-extraction of bitter compounds. Budget machines often have limited temperature control — a PID controller (built into many prosumer machines) maintains precise, consistent temperature and is worth the premium for shot-to-shot consistency.
What is a group head and why does it matter?
The group head is the component where the portafilter locks in and through which water flows into the coffee puck. It's thermally massive in quality machines to maintain consistent brewing temperature. The E61 group head (found on Rocket, ECM, and Lelit machines) is the most common prosumer design — it's thermally stable, durable, and easy to service. The quality and thermal mass of the group head directly affects temperature consistency from shot to shot.
What is an OPV and why does it matter for espresso?
An OPV (Over Pressure Valve) limits the maximum pressure in the brewing circuit — it should be set to 9 bar for espresso. Many entry-level machines (especially older Gaggia Classic models) ship with the OPV set too high (12–15 bar), which over-extracts and produces harsh espresso. Adjusting the OPV to 9 bar (or 8.5 bar per the original La Pavoni spec for some enthusiasts) is one of the first modifications home baristas make to improve shot quality.
Key Terms
Espresso
A concentrated coffee brewed by forcing hot water (90-96°C) through finely ground coffee at 8-9 bars of pressure for 25-35 seconds. Produces 30-40ml of intense, full-bodied liquid with crema on top. The base for lattes, cappuccinos, and americanos. Requires precise grind, dose, and technique.
Cold Brew
Coffee brewed by steeping coarsely ground coffee in cold or room-temperature water for 12–24 hours. Cold brew produces a low-acid, smooth concentrate often served diluted over ice or used as a base for espresso-style cold drinks.
Pour-Over
A manual filter brewing method where water is poured by hand over a bed of ground coffee. Popular brewers: Hario V60, Kalita Wave, Chemex. Offers maximum control over brew variables. Produces a clean, nuanced cup. Requires a gooseneck kettle and scale for best results.
