When ordering at a café, you often hear the phrase "add a shot," but how much coffee does this shot actually represent?

Starting from Front Street Coffee's production experience, this article systematically sorts out the basic concept of Espresso, the differences between single and double espressos, the production process and qualified standards, and combines the Feima E98 coffee machine to give specific extraction parameters for hot lattes and suggestions for milk-to-coffee ratios.

The standard espresso ratio is 1:2—a single shot uses 9g of grounds to yield 18g of liquid, and a double shot uses 18g of grounds to yield 36g of liquid. When actually pulling a shot, fine-tune based on this brew ratio and the taste. The grind size for espresso is also adjusted by referencing this extraction time: if it runs fast, grind finer; if it runs slow, grind coarser, until the extraction time matches. [more…]

To make a decent espresso at home, the coffee-to-water ratio and grind size are two core variables you can't avoid. Standard espresso is usually based on 1:2, with a single shot using about 9 grams of coffee to extract 18 grams of liquid, and a double shot using 18 grams of coffee to 36 grams of liquid, but the actual output still needs fine-tuning based on how it tastes that day. The most intuitive way to judge whether the grind size is right is the extraction flow rate: if the liquid comes out too fast, the grind is too coarse and needs to be made finer; if the liquid comes out too slow, the grind is too fine and needs to be made coarser, until the extraction time falls within a reasonable range. Besides the parameters, the choice of beans is equally key—medium-dark roast blends or darker are more likely to achieve a balanced, stable flavor. This article will organize an actionable set of adjustment ideas around dose, ratio, grind size, and extraction time. [more…]

What kind of coffee beans should be used to make espresso? [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. 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.

Many people notice a layer of fine black powder at the bottom of the cup after finishing a latte or espresso, and sometimes dark particles float at the bottom of an iced latte as well. Is this actually normal? Does it affect flavor or health? In fact, this sediment consists of ultra-fine particles that pass through the filter basket holes during espresso extraction. A trace amount is normal, but if a large amount of grounds is visible to the naked eye, it means something has gone wrong in the extraction process. This article starts with where these fine particles come from, analyzes possible factors such as grinding, the portafilter basket, and barista technique, and offers practical solutions like adjusting the grind setting, switching baskets, and adding a paper filter, to help you enjoy a cleaner cup of coffee.

The brew ratio of espresso is one of the key factors determining its flavor expression. The standard ratio is usually 1:2, meaning a single shot uses 9 grams of coffee to extract 18 grams of liquid, while a double shot uses 18 grams of coffee to extract 36 grams of liquid. However, in actual production, fine-tuning based on taste is still necessary. Starting from the definition of espresso, this article will provide a detailed analysis of its taste characteristics, the correct way to drink it, and the adjustment logic of core extraction parameters such as dose, liquid weight, and grind size.

Crema is the layer of foam formed when carbon dioxide and fats emulsify during espresso extraction. [more…]
