I. The Basics & Sourcing

Technically, no. It’s the seed of a fruit called a "coffee cherry."

It’s coffee that scores 80+ points on a 100-point scale by certified tasters (Q-Graders).

Single-origin comes from one place (farm or region); a blend mixes origins for a specific, consistent flavor.

The roaster buys directly from the farmer, cutting out middlemen to ensure higher pay for the producer.

Arabica is sweeter and higher quality; Robusta is more bitter, heartier, and has double the caffeine.

II. Roasting & Freshness

It doesn't "spoil" like milk, but it goes stale. Use it within 4 weeks of the roast date for best flavor.

No. Strength is determined by your brew ratio. Dark roast just tastes more "bitter."

Light roasts are denser and often have slightly more caffeine by volume.

The day the beans were roasted. Always look for this on the bag instead of a "Best By" date.

In an airtight, opaque container at room temperature. Never in the freezer!

III. Brewing Mastery

Usually "under-extraction"—either your water was too cool or your grind was too coarse.

"Over-extraction"—your water was too hot, your grind was too fine, or you brewed it too long.

Yes. Measuring by weight (grams) instead of scoops is the #1 way to get a consistent cup.

Filtered water. If your water tastes bad from the tap, your coffee will too.

Absolutely. Coarse for French Press, medium for Drip, and fine for Espresso.

IV. Gear & Espresso

Per ounce, yes. But a standard 8oz cup of coffee has more total caffeine than a 1.5oz espresso shot.

Yes! "Espresso Roast" is just a suggestion from the roaster; any bean can be brewed as espresso.

Usually, the beans are too old or the grind isn't fine enough.

Yes. Blade grinders chop unevenly. Burr grinders produce uniform pieces for even extraction.

Daily for the carafe/portafilter, and "descale" the internal pipes every 3 months.

V. Health & Lifestyle

Studies suggest it's rich in antioxidants and may lower risks for certain diseases, but moderation is key.

No, it’s usually about 97% caffeine-free.

It’s a rush of caffeine. Try eating food first or switching to a darker roast, which some find "smoother."

Generally yes, but doctors usually recommend limiting intake to under 200mg a day.

For many people, yes! It stimulates muscle contractions in the digestive tract.
