When ordering at a coffee shop, you often hear the phrase "add a shot," but do you know what 1 shot actually refers to? In the early days, 1 shot was a 30ml single espresso extracted from 9–11g of grounds, whereas today at most cafés, 1 shot is actually a double espresso extracted from 18–20g of grounds. Why would shops rather pull doubles than use single baskets? What exactly are the differences between single baskets and double baskets in appearance, structure, and extraction performance? Starting from Front Street's extraction experiments, this article uses concrete data to explain why single baskets have been phased out, and analyzes how basket structure affects water flow distribution, extraction uniformity, and channeling, helping coffee enthusiasts understand the extraction logic behind espresso.

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.

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.
