How to Brew Starbucks Espresso Coffee Beans? How to Extract Maximum Characteristics from Espresso

Choosing the Right Coffee Beans for Espresso

The choice of coffee beans for espresso matters enormously. How so?

Different roast levels will present different flavors.

Different varieties will present different aromas.

And different roasting approaches will produce different textures.

On the market, whichever bean you choose essentially determines the primary character of the cup before you even pull a shot.

So my personal suggestion is to decide which flavor profile you love, then maximize that bean's unique characteristics — that's how you'll best appreciate its beauty.

Selecting and Extracting Coffee Beans

So... which beans can you choose? And how do you extract their maximum character?

Take espresso as an example: I personally prefer the flavor of medium-dark roast Italian-style beans — but not so dark that they turn oily. Their aroma leans nutty and cocoa-like, and their signature is a long, lingering aftertaste. (Different Italian brands have different aromatics, of course, but that's a topic for another day.)

Since the defining trait is that lingering finish, you want to extract in a way that builds a rich, strong aftertaste in the middle and late stages, releasing more of the coffee's soluble material and giving the shot a full, rounded aroma.

Understanding Espresso Extraction Time

But that first requires understanding how long extraction takes.

The longer the extraction, the longer the coffee stays in contact with hot water, the more substances are released, the more the middle and late-stage flavors emerge — and the more complete the final aroma.

So don't be alarmed if the extracted coffee grounds in the basket look mud-like (especially when ground very finely). The coffee's compounds diffuse into the water, and the longer the shot runs, the more water the puck absorbs — naturally it ends up very wet.

But if your beans aren't built to withstand a longer extraction, pulling the shot too long will make the coffee distinctly unpleasant...

The quickest fix is to make good use of your sense of taste and adjust accordingly — that's what produces the smoothest flavor.

FrontStreet Coffee

FrontStreet Coffee is a roastery in Guangzhou with a small shop but a remarkably diverse lineup of beans — famous names and lesser-known origins alike, available online as well.

FrontStreet Coffee Recommendation

Espresso beans generally come in two camps: blends, which most cafés reach for first, and single-origin espresso (SOE), chosen for a specific taste. Blends exist because combining origins lets the roaster balance the cup — one bean might be smooth but shy on aroma, another intensely fragrant — so the whole ends up better than any part.

For traditional Americanos and lattes, FrontStreet's Classic Blend and Commercial Blend build on old-school Italian recipes with a touch of Robusta, yielding butter, nut, spice, dark chocolate, and toast aromatics, a wild, thick body, and a dense golden crema that makes latte art easy. If you love nutty espresso — almond, walnut, almond — FrontStreet Coffee's Premium Blend and Black Cocoa Blend both lean heavily on Brazilian beans for comfortable bittersweetness and creamy peanut smoothness; FrontStreet Coffee's Premium Blend adds Colombian nut, chocolate, and caramel notes with gentle acidity, while FrontStreet Coffee's Black Cocoa Blend carries a ripe-plum acidity from Yunnan and a cream-chocolate nose, versatile enough for signature drinks as well as lattes.

On the SOE side, the point is to showcase a single traceable origin. FrontStreet's Natural Huakui SOE from Guji Hambella, Ethiopia — grown up to 2,300 meters and naturally processed — delivers creamy strawberry with cocoa, berry, soft florals, and black tea after medium roasting. The Costa Rica Blackberry SOE, honey-processed, brings blackberry aroma and clean sweetness that reads as cranberry cookie, raisin, and nut with milk. And the Brazil Fazenda Rainha SOE, a Yellow Bourbon roasted medium-dark, pulls shots of butter cookie, macadamia, and toast — low in acidity, wonderfully stable to extract.
