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.

Many coffee enthusiasts have noticed that after switching on, coffee shops often pour away the first espresso pulled before they begin serving drinks as normal. Behind this seemingly wasteful gesture are actually multiple considerations, including cleaning powder residue, overnight coffee grounds, and machine parameters that have not yet stabilized.

Many coffee enthusiasts operating semi-automatic espresso machines at home will notice a detail: the first espresso extracted right after the machine is turned on is often poured straight down the drain. This is not waste, but an early-tuning routine followed by both professional coffee shops and experienced home baristas. Why exactly can't this espresso be drunk? What systematic preparatory work do coffee shops do before officially opening? What role does espresso cleaning powder play in this? This article will focus on the daily startup routine of espresso machines, explain why the first shot of espresso is discarded, and comprehensively lay out the standard steps for in-store morning tuning, while also explaining the uses of cleaning powder and recommendations for choosing it.

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.

When pulling espresso, you occasionally get distracted and stop before the liquid weight reaches the target. Can you press the brew button again to make up the missing amount? Front Street ran a set of controlled experiments using its own Front Street Strawberry Candy · Espresso: first, a normal espresso was made, then extraction was cut off at one-half, two-thirds, and four-fifths of the target liquid weight and restarted, and a refractometer was used to measure and compare the flavors. The results showed that the earlier the extraction was cut off, the greater the gap in concentration and extraction yield, and the thinner the mouthfeel. The reason is related to changes in puck resistance under pressurized extraction. If you have also encountered the situation of cutting off and then topping up the shot, this hands-on test can give you clear operating advice. [more…]

As the base of fancy coffee drinks, the choice between single and double shots of espresso has always been a topic of interest for enthusiasts.

On the first day back to work, a customer ordered a large Reserve iced Americano at Starbucks, which should have contained four shots of espresso, but only received three. After the staff admitted the mistake, they added an extra shot without asking and returned the drink. This was not an isolated incident; previously, the same store had also missed caramel drizzle on a Caramel Macchiato. Consumers began to question whether Starbucks was cutting corners in its offerings, while employees explained that Reserve bean hoppers typically extract two shots at a time, so normally two extractions would yield four shots, and the shortage was likely due to a misremembered recipe. Meanwhile, on social media, there were continuous complaints about Starbucks lattes tasting weak, hot drinks not filling the cup, and missing hazelnut pieces on whipped cream, along with occasional issues with service attitude. Some employees revealed that after accelerated store expansion, training time was compressed, staff quality varied, and quality control became unstable.

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.

Front Street Coffee uses the Warm Sun blend, testing with 20g of grounds extracted to 40ml at a 1:2 brew ratio, to reveal why under pressurized extraction, changes in the puck structure cause an overly fast flow rate and under-extraction during a second extraction, along with operational recommendations.
