Tempering 101: 3 Types to Know

As a coffee lover, you probably know that there are several ways to get your daily caffeine fix, from espresso shots to cold brews. But have you ever stopped to think about the science behind your coffee? One important aspect of coffee brewing is tempering. In this article, we will cover the basics of tempering, the reasons why it matters, and the three main types of tempering you should know about.

What is Tempering and Why is it Important?

Tempering is a process that involves heating and cooling chocolate or coffee beans to achieve specific results. For coffee, tempering is the process of heating and then cooling roasted coffee beans to improve their flavor profile. The goal of tempering is to prevent the beans from developing an unpleasant taste or aroma. Without proper tempering, coffee beans can taste sour, bitter, or burnt.

There are three main types of tempering that are commonly used in coffee brewing: pre-brew, post-brew, and post-roast. Each of these types serves a specific purpose and can affect the flavor and aroma of your coffee.

Pre-Brew Temper

The pre-brew tempering process involves heating the water to a specific temperature before brewing the coffee. The water temperature is usually around 195 to 205 degrees Fahrenheit, which is the optimal temperature for extracting the most flavor from coffee beans. Pre-brew tempering helps to ensure that the coffee grounds are fully saturated and that the flavors are properly extracted.

Post-Brew Temper

Post-brew tempering is the process of cooling the coffee after it has been brewed. This process is important because it prevents the coffee from continuing to extract flavor, which can lead to over-extraction and a bitter taste. Post-brew tempering can be achieved by transferring the coffee to a carafe or by pouring it into a cup and letting it cool naturally.

Post-Roast Temper

Post-roast tempering involves cooling and resting the coffee beans after they have been roasted. This process is important because it allows the beans to develop their full flavor potential and to release any leftover gases from the roasting process. Post-roast tempering usually involves cooling the beans quickly and then allowing them to rest for several hours before being packaged or ground.


Tempering is a crucial aspect of coffee brewing that can affect the flavor and aroma of your coffee. Knowing the three main types of tempering – pre-brew, post-brew, and post-roast – can help you create a perfect cup of coffee every time. Whether you are a coffee aficionado or just someone who enjoys a good cup of joe, understanding the basics of tempering can help you appreciate the science behind your coffee and enhance your overall coffee experience.
