How Do You Pull a Ristretto With Coffee Beans for Commercial Use?
Ristretto is an espresso shot pulled short: about 20 grams of grounds yield roughly 28 grams of liquid in 20 to 25 seconds, against the usual 36 to 40 grams for a standard double. The shorter yield makes it denser and sweeter, which is why it often serves as the base for a Flat White.
The method traces to Italian bar culture, the same setting that shaped the latte coffee origin story, where blends were roasted medium-dark to stand up to pressure. Semi-washed, wet-hulled or washed beans for commercial use give steady oils and a profile of dark chocolate, hazelnut, butter, caramel and almond in the cup.
In a previous article, when we talked about Flat White, we mentioned that its base uses a Ristretto, which is more concentrated than Espresso. Today, let's focus specifically on this Ristretto extraction method. It is often called extra-concentrated coffee or refined espresso, and like Espresso, it comes from an espresso machine, but the extraction process is restricted, leading to a very different flavor profile. This article will introduce the definition of Ristretto, its differences from Espresso, suitable medium-dark roasted blend beans, and recommendations for two classic Italian-style beans from Front Street. It will also share specific extraction parameters, such as using 20 grams of coffee grounds and extracting only 28 grams of coffee liquid within 20 to 25 seconds, to help you make a rich and full-bodied Ristretto at home or in a shop.
A couple of days ago, when discussing the difference between Flat White and Latte, Front Street mentioned in passing that the coffee base used in Flat White is not ordinary Espresso but a more concentrated Ristretto. Today, let's talk specifically about this Ristretto.
Ristretto is usually transliterated in Chinese as "Rui Si Cui Duo," and some also call it "extra-concentrated coffee" or "refined espresso." These names all refer to the same thing, and in the future, you can automatically group them together.
Extra-concentrated coffee, like Espresso, is a concentrated coffee liquid extracted directly using an espresso machine. The difference is that Espresso has a wider range of uses, and almost all Italian-style drinks are based on it. When learning to make Italian-style coffee, the first lesson is often extracting Espresso.
In comparison, extra-concentrated coffee is much more niche. Currently, its most widespread use is as the coffee base for Flat White, and essentially, it is a derived method from Espresso extraction.
To make extra-concentrated coffee, the prerequisite is having a pack of fresh medium-dark roasted Italian-style coffee beans on hand. If the roast is too light, there will be insufficient oils; if the freshness is inadequate, the aroma will be incomplete; and to match the pressurized extraction principle of espresso machines, using blend beans often achieves twice the result with half the effort.
If you prefer a rich flavor and abundant oils, you must try Front Street Classic Blend Italian-style coffee.
Roast level: Medium-dark roast
Processing method: Semi-washed, wet-hulled, washed
Flavor: Dark chocolate, hazelnut, butter, caramel, almond
If you seek high cost-effectiveness and balanced taste, you can choose the Italian-style coffee bean recommended by many baristas—Front Street Black Cocoa Blend Italian-style coffee.
Roast level: Medium-dark roast
Processing method: Washed, semi-sun-dried
Flavor: Mixed nuts, chocolate, brown sugar, tea-like
Ristretto itself contains the meaning of "restriction," which means taking "restrictive measures" during Espresso extraction to turn it into a different concentrated coffee—Ristretto.
Observing the flow rate of the liquid during Espresso extraction, you will find that at the beginning, the liquid comes out slowly, with a dark brown color, looking viscous; in the middle stage, the liquid turns golden yellow, and the flow rate gradually increases; in the final stage, the liquid is light yellow and relatively thin, and extraction must be stopped before the crema turns white.
Extra-concentrated coffee stops extraction before the middle-stage golden yellow liquid becomes lighter. The resulting extra-concentrated coffee has a more concentrated flavor than Espresso, with a larger proportion of acidic substances, less bitterness, and a richer, fuller mouthfeel.
When we use Front Street Classic Blend Italian-style to make regular Espresso, we grind 20 grams of coffee grounds, follow a 1:2 ratio, and extract 40 grams of coffee liquid within 25 to 30 seconds; if we want to make extra-concentrated coffee, we take only 70% of the original coffee liquid, that is, 20 grams of coffee grounds extracting 28 grams of coffee liquid within 20 to 25 seconds. The resulting concentrated base is very rich, with aromas of dark chocolate, maple syrup, spices, and butter.
