When ordering an espresso at a coffee shop, you can ask for a single shot or a double shot.

When ordering at a coffee shop, have you ever noticed the filter basket the barista uses? A single basket typically holds 9–11g of coffee grounds for pulling a single espresso; a double basket can hold 18–22g for a double espresso. But in reality, most cafés would rather use a double basket to pull an extra shot—even pouring half of it down the drain—than switch to a single basket. Why is that? Starting from Front Street's comparative experiments, this article takes a deep dive into the structural differences, extraction performance, and consistency issues of the two baskets, helping you fully understand which basket a single espresso should actually use.

In coffee competitions, double grinding was once seen as a means of precisely controlling particle size, but the actual practice is far from simple. Sending coffee grounds through the grinder again not only multiplies the amount of fines, but also worsens the "retention" problem—especially in electric grinders, where it can leave a large amount of grounds behind, making cleanup time-consuming and laborious. This article uses Front Street's experimental data to analyze in detail the impact of double grinding on the grinder, compares the differences between electric and hand grinders in this process, and offers alternative extraction adjustment solutions to double grinding, helping you improve extraction efficiency without disassembling your machine.

How much coffee powder should actually be used for 1 shot of espresso? The traditional standard is 9-11 grams, but this parameter is rarely adopted today, and the root cause lies in the special structure of the single-shot filter basket. The single-shot filter basket is shaped like an inverted cone, with the upper half having the same diameter as the double-shot, while the lower half narrows to maintain the depth of the coffee bed, yet the actual extraction performance is far more complex than "half of a double shot." Precisely for this reason, single-shot filter baskets have gradually fallen out of favor, and more baristas have shifted to double-shot filter baskets, producing one espresso at a 1:2 coffee-to-liquid ratio. In this article, Front Street Coffee will use the Sunflower · Warm Sun blend beans that are standard in our stores, paired with a double-shot filter basket, to fully demonstrate the standard process from weighing the coffee, distributing the grounds, and tamping to extraction and tasting, and to share practical suggestions for adjusting time, flow rate, and flavor.
