What is Cold Brew?

Cold brew coffee is a type of coffee that has been brewed SLOWLY over an extended period of time using COLD or room-temperature water [1].

This process results in a much SMOOTHER, less acidic cup with more pronounced flavor notes than regular hot-brewed coffee. Cold brew also contains significantly LESS caffeine because the LOWER temperatures don’t extract as much from the beans.

The result is an even-bodied, sweet and REFRESHING beverage that can be enjoyed without any added sugar or creamers. Additionally, cold brews are often served on ICE to bring out their full flavor profile and keep them cool for LONGER periods of time.

How to Choose Coffee Beans for Cold Brew

When it comes to making a GREAT cold brew, the type of coffee beans you use are essential. This is because different types of beans have DIFFERENT levels of acidity and flavor notes that will affect the OVERALL taste of your cold brew.

Therefore, when choosing coffee beans for cold brew, it’s IMPORTANT to consider the origin and roast level as well as what kind of flavor PROFILE you want in your drink.

For instance, if you prefer a SWEETER cup with more pronounced notes, then light or medium-roasted coffees from Latin America would be BETTER than dark roasts from Africa, which tend to be more BITTER.

Pro Tip: Some specialty blends may also work well depending on what flavors you’re going for in your finished product.

Dark roast coffee beans are the most COMMON choice for cold brews because of their low acidity and bold, robust flavor. However, if you prefer a SMOOTHER cup with more subtle notes, LIGHTER roasts from Central America or Ethiopia might be better suited for your taste.

It’s also important to use COARSELY-ground coffee for cold brews. This will help prevent over-extraction and ensure the cold brew isn’t TOO bitter.

When shopping for coffee beans SPECIFICALLY for cold brewing, look out for labels such as “cold brewed” or “for slow extraction”, as these typically indicate that they were specifically blended and ROASTED with this purpose in mind.

Pro Tip: Remember always to buy fresh beans so that all their flavor compounds can be extracted during the brewing process.
