When ordering an espresso at a coffee shop, you can ask for a single shot or a double shot. On the surface, single and double espressos differ only in volume, but from the barista's operational perspective, this involves two completely different extraction schemes. Portafilter basket capacity, puck structure, and uniformity of pressure distribution can all create noticeable differences in the final product. This article starts from Front Street Coffee's extraction experiments, using specific data to compare the extraction performance of single baskets versus double baskets, explaining why a single espresso is not simply half of a double, and includes a standard double espresso preparation procedure to help you gain a deeper understanding of the intricacies behind this small cup of coffee.

If you want to order an espresso at a coffee shop, besides saying "I'll have an espresso," you can also say "I'll have a shot." A shot is the unit for espresso; 1 shot espresso means one serving of espresso, and sometimes "sin" is also used. [more…]

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.

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.

When ordering at a coffee shop, you often hear the phrase "add a shot," but do you know what 1 shot actually refers to?

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.
