Why Thick Crema Espresso Tastes Amazing and How to Brew It

You’ve seen those thick, almost syrupy espressos with a crema so dense it looks like soy sauce paste—but does it actually taste good? And more importantly, how do you make one? This article breaks down everything from crema texture and extraction timing to bean freshness, with hard numbers and no fluff.

Yes, espresso with thick, dark crema like 'soy sauce paste'—what the author calls ''—tastes intensely strong with a sweet finish, and the aftertaste can last 40–50 minutes. To get this, you need an 8.5-bar stable pressure, correct water temperature, and beans roasted less than five days ago.

What ‘’ Espresso Really Means

The author describes their espresso crema as resembling ‘soy sauce paste’ —thicker and darker than standard crema. This visual cue signals a very dense, stable crema formed under consistent 8.5-bar pressure. The resulting shot is not just visually striking but also intense, sweet, and leaves a lingering aftertaste for up to 40–50 minutes. This level of crema is hard to achieve commercially, especially with beans that aren’t freshly roasted.

Why Freshness Is Non-Negotiable

To achieve this ideal espresso, bean freshness is critical. The author insists on using coffee roasted within five days. Beyond seven days, the volatile aromas and delicate flavors dissipate, resulting in dull, flat shots—even if the beans are high-quality origins. Commercial roasters like Caravali or Allegro often use beans that have lost their freshness during transit, leading to muted espresso. Even well-known chains like Starbucks over-roast their beans to a coal-like darkness, which masks origin character and results in bitter, undrinkable espresso past ten days post-roast.

How Long Should Espresso Extraction Really Take?

The ideal extraction time is 25–27 seconds, measured from when the pump starts—not when the coffee begins to flow. Most people start timing when they see espresso coming out, but there’s roughly a 5-second delay before flow begins. That means your actual target is 25 seconds of actual brew time. If extraction is shorter than 25 seconds, the crema will be pale and the shot under-extracted. Many shops in Taiwan, the author notes, produce shots with extraction times far shorter than this, resulting in weak espresso. Crema alone doesn’t mean good espresso—it’s just the starting point. Precision in grind size and machine settings is required to hit that 25-second window.

The Right Dose and Shot Volume

The author’s preferred espresso volume is around 40cc, which they refer to as a double shot, specifically an ‘Espresso Ristretto’. While not explicitly defined here as a traditional ristretto (which is typically a more concentrated 25cc shot), this 40cc double likely refers to a slightly shorter pull than a full 60cc normale, emphasizing intensity over volume.

Grind Size, Machine Quality, and Barista Skill

To consistently hit the 25-second extraction window, you need a fine, uniform grind. Entry-level grinders like the Baratza KMM30 can’t achieve the necessary fineness. The author recommends higher-end grinders such as Rancilio or Mazzer/Povoni models. More importantly, none of the best equipment matters without barista skill. The operator—who the author calls the true expert, or barista—must manage every variable: dose, grind, tamp, water pressure, temperature, and timing. Good espresso isn’t about the machine; it’s about the person pulling the shot.

What the Author Thinks of Commercial Brands

The author is highly critical of major commercial roasters. Starbucks is singled out for over-roasting beans to a coal-like degree, making even fresh shots harsh and undrinkable. Past ten days, Starbucks coffee is dismissed as terrible. Caravali beans are described as only marginally better than bad, and Allegro isn’t much better. The beans these companies supply are often stale by the time they reach consumers, ruining the flavor profile before brewing even begins.

The Author’s Espresso Challenge and Goals

The author rates most Taiwanese espresso as zero out of 100, commercial blends like Pro (25 points) and Oley (30 points) as mediocre, and their own modified Rancilio setup with freshly roasted beans at 50 points. Using a La Marzocco machine with precise control over water flow, temperature, and pressure curves could, in theory, reach 65 points. The author plans to open an espresso shop in Taipei featuring a heavily modified air-bed roaster with full control over airflow and temperature curves, along with a customized La Marzocco machine to hit an ambitious 80-point espresso.

Frequently Asked Questions

What does '' crema mean and why does it matter?

'' crema refers to an extremely dense, dark espresso crema that resembles soy sauce paste in texture and appearance. It indicates a stable, well-extracted shot under consistent 8.5-bar pressure. This type of crema is visually striking and often correlates with a rich, sweet espresso with a long aftertaste—up to 40–50 minutes—which is considered a sign of high-quality brewing.

How long should espresso extraction take and why is 25 seconds ideal?

Ideal espresso extraction time is 25–27 seconds, measured from when the pump is turned on (not when coffee first appears). Most shops don’t account for the ~5-second delay before flow starts, so the target is a 25-second actual brew time. Less than 25 seconds leads to under-extracted, pale crema. Timing from pump activation ensures proper yield and flavor balance.

Why is bean freshness so crucial for good espresso?

For the best espresso, use beans roasted within five days. After seven days, aromatic compounds and fresh roast flavors dissipate, leading to dull, flat shots. Even high-quality beans lose their vibrancy, resulting in muted or unpleasant espresso. Commercial roasters often deliver beans that are already stale by the time they reach the consumer, which is why fresh, properly roasted beans are emphasized.

Does crema alone mean good espresso?

No. Crema is important but not the sole indicator of quality. The author stresses that achieving 25-second extraction with proper grind, dose, and pressure is more critical. Thick crema can result from good pressure, but the shot must also taste balanced, sweet, and have a lasting aftertaste to be considered truly good espresso.

What’s the ideal espresso dose and volume according to the author?

The author prefers a double shot with around 40cc volume, referring to it as an Espresso Ristretto. While not a classic ristretto (which is usually ~25cc), this suggests a shorter-than-normale pull (~60cc) for more intensity. Exact brew ratios aren’t specified, but volume and concentration are clearly prioritized.

Can you make great espresso with a cheap grinder or home machine?

Not likely. The author notes that entry-level grinders like Baratza KMM30 can’t grind fine or uniformly enough for 25-second extraction. They recommend higher-end grinders like Rancilio or Mazzer. Even with a good machine, extraction depends on precise grind size, dose, tamp, and timing—all of which require skill and quality equipment to align properly.
