Coffee enthusiasts often ask, what exactly is the difference between espresso and single-origin coffee? At first glance, these two concepts seem clearly distinct, but upon closer examination, you'll find that the boundary between them is actually much blurrier than you'd imagine. This article will start with the basic concepts and gradually analyze whether single-origin coffee beans can be used to make espresso, under what circumstances espresso can be classified as single-origin coffee, and where the core distinction between the two ultimately lies. If you've ever been confused by these two terms when ordering or brewing at home, why not follow Front Street Coffee and sort through it together.

A friend asked me a question a few days ago: what exactly is the difference between espresso and single-origin coffee? I thought about it for a long time and found that giving a clean, decisive answer is really not easy. I always feel that the line between these two has become increasingly blurry. So I might as well write this article and organize my thoughts properly.

Let's start with the basic definitions of these two types of coffee, and then I'll talk about some of my personal confusions.

I. Basic definitions of espresso and single-origin coffee.

Espresso: If we must use specific parameters to explain it, it's roughly like this — take 7 grams of coffee grounds, extract with 92°C hot water under 9 atmospheres of pressure for 25 to 30 seconds, and finally get about 30 milliliters of coffee liquid. This cup is espresso.

Single-origin coffee: The coffee beans come from only one country or one specific region. Coffee made from beans of this single source is called single-origin coffee.

II. Can single-origin coffee count as espresso?

I used to think that espresso had to be made with blended beans to be authentic. But over the past few years, I've observed that using single-origin coffee beans to make espresso has gradually become a popular practice.

This overturns my previous understanding. In fact, from the definition given above, it's clear that a cup of coffee made from single-origin coffee beans using the espresso extraction method also belongs to the category of espresso.

III. Can espresso count as single-origin coffee?

Since single-origin coffee can be espresso, then conversely, can espresso also be classified as single-origin coffee? The answer is: it depends. This needs to be discussed in two scenarios, and the key lies in the type of coffee beans used. If this cup of espresso uses single-origin beans (such as Brazil, Colombia, Mandheling, etc.), then I think it can also be called single-origin coffee.

Conversely, if this cup of espresso is made with blended beans, then in my view it cannot be called single-origin coffee.

IV. Where is the most fundamental difference between espresso and single-origin coffee?

Based on the analysis of the above three aspects, we can draw this conclusion: espresso may or may not be single-origin coffee, and the key to distinguishing them lies in the type of coffee beans used.

And single-origin coffee may or may not be espresso, and the basis for judgment then becomes the concentration of the coffee liquid. For example, Colombian coffee brewed with a siphon cannot be called espresso, but Colombian beans extracted in espresso style with a coffee machine can be called espresso.

The difference between espresso and single-origin coffee is indeed a rather headache-inducing topic. The above is all my personal understanding. If any of you have different views on this issue, Front Street Coffee would be happy to discuss and exchange ideas with everyone.
