FAQ
Common questions
How much does it cost to start making real espresso at home?
Realistically, $585 minimum: Bambino Plus ($350) + Baratza Encore ESP ($180) + Normcore tamper ($35) + knock box ($20). Add an OXO scale ($55) if you don't have a kitchen scale, bringing the typical kit to around $650. These aren't luxury prices — they're the floor for equipment that actually extracts espresso correctly.
Can I use pre-ground coffee for espresso?
No. Espresso requires a grind so fine and consistent that it has to happen right before extraction. Pre-ground coffee, even labeled for espresso, stales within minutes of grinding — the aromatic compounds that make espresso taste like espresso disappear quickly. More practically: you can't adjust pre-ground coffee when your shot is pulling wrong. The grinder is how you dial in.
What coffee should I buy for espresso?
Start with a medium roast espresso blend from any reputable specialty roaster — Counter Culture, Onyx, Intelligentsia, or a local roaster. Blends are designed to taste good across a range of extraction variables, which is exactly what you want while you're still learning. Light single-origin espresso is harder to dial in and more unforgiving of errors; save it for after your first 50 shots.
Why does my espresso taste sour?
Under-extraction. The most common cause is a grind that's too coarse — water moved through too fast and didn't pull enough from the coffee. Grind finer, pull again, taste again. If it's still sour at a very fine grind, your dose might be too low or your water temperature too cool.
Why does my espresso taste bitter?
Over-extraction. Grind is too fine, shot took too long, water pulled too much from the coffee. Grind coarser. If it's still bitter at a coarse grind, check your water temperature (too hot extracts bitter compounds) or your dose (too much coffee in the basket can choke the shot).
What's the difference between a latte, flat white, and cappuccino?
Milk ratio and texture. A cappuccino is equal parts espresso, steamed milk, and milk foam — small, strong, airy. A latte is mostly steamed milk with a thin layer of foam — larger, milder. A flat white is like a small latte with microfoam throughout — very velvety, no foam layer. All start with the same espresso; the milk texture and ratio changes everything.
