Two of the mainstays in the coffee arena are cold brew and espresso. While cold brew’s popularity exploded in the 2010s, espresso has been a hot choice for a lot longer—and isn’t going anywhere.
What are the main differences between these two popular coffee types, and which one is right for you? Read on for our ultimate guide to cold brew vs espresso, exploring coffee flavor profiles, brewing methods, and more.
What is cold brew?
Cold brew is created by steeping ground coffee in room temperature or cold water for six to 20 hours, creating a concentrate diluted with water and served over ice.
Taste-wise, the dilution process gives cold brew a sweeter, less intense flavor profile than traditional hot coffee. For some, this is a more approachable alternative to regular coffee—cold brew is often described as less acidic and more floral or smooth.
Cold brew’s history
Cold brew has a fascinating history that goes back hundreds of years. Dutch traders introduced cold coffee to Japanese sailors in the 17th century as an alternative to hot brewing methods that required fire, which was a dangerous cooking component on ships.
Today, the cold brew tradition in Japan has evolved. Japanese or Kyoto-style brewed coffee is created by dripping water one drop at a time through glass apertures suspended in a tower shape, taking up to 5 hours to produce one batch of cold coffee.
What is espresso?
Espresso can refer to two different elements in the coffee world: a brewing method, and a specific coffee beverage. The two may seem interchangeable, but there are some major differences.
Espresso as a brewing method
Espresso often refers to a brewing process that creates a very distinct, desirable form of brewed coffee that serves as a base component of many cafe offerings. The process is complex and varies depending on several factors, including:
● Region
● Equipment
● Preference
However, today’s definition of the traditional Italian espresso is as follows:
Hot water pressure is applied to a compact, tamped “cake” of ground, roasted coffee beans for 25-30 seconds by a percolation machine, yielding a small cup of concentrated, foamy coffee.
This type of brewing process is performed by an espresso machine, of which there are many variations. In fact, home espresso machines now make it possible to brew your espresso from the comfort of your kitchen, and they come in compact sizes that don’t take up an entire countertop.
Espresso as a beverage
As you likely already know, espresso doesn’t just refer to the machine and the brewing style—it’s also a beverage in and of itself.
Espresso is one of the core components of cafe drinks like lattes or mochas, but you can also drink it plain. Typically, an espresso is served in “shots” of one to two oz. servings and is thicker than drip coffee. Espresso also has a layer of “crema” on top—an aesthetically pleasing and tasty byproduct of air bubbles mixing with the coffee’s oils.
The rich history of espresso
Like cold brew, espresso has a history that goes back hundreds of years. However, instead of Japan, the beginnings of espresso coffee trace back to Italy.
In the 19th century, innovations utilizing steam-powered technology took Europe by storm. In 1884, Angelo Moriondo of Turin, Italy was granted a patent for a brand new steam machine capable of “economic and instantaneous confection of coffee beverage.”
In 1906, Luigi Bezzera and Desiderio Pavoni of Milan introduced an improved espresso machine at the Milan International Exposition. This machine featured a pressure release valve and a steam wand, and they debuted their stall with a sign reading “Caffe Espresso”—effectively creating the world’s first espresso bar.
