Cold brew coffee is made by steeping coffee grounds in cold water for a long time. Because low-temperature extraction has a high tolerance for error, it usually does not over-extract easily. But in practice, many people still end up with cold brew that has obvious bitterness, muddled flavors, and astringency. The problem often lies in four areas: using hot water for blooming or warm water for steeping, choosing dark-roast beans, steeping for too long, and using too large a coffee-to-water ratio, which leads to too high a concentration. In this article, Front Street breaks down the extraction principles behind these improper practices one by one, and gives specific recommendations for regular water temperature, grind size, coffee-to-water ratio, and steeping time, while also explaining what scenarios the 1:10 and 1:12 ratios are suitable for. If your cold brew also tastes bitter, you may want to troubleshoot by comparing it against these points. Once you find the root cause, you can consistently make a smooth cup of cold brew coffee.

To make a delicious cold brew coffee at home, the key is to master a few parameters: grind size, coffee-to-water ratio, and steeping time. Cold brew coffee is different from regular hot water brewing—it relies on long steeping or dripping with cold water to extract the coffee liquid. Common forms include cold steep and ice drip. Because extraction efficiency is low at low temperatures, the production time usually takes 6 to 8 hours or even longer, but in return you get a richer flavor and a fuller body. Refrigerated storage generally keeps it good for 3 to 5 days. This article covers cold brew coffee equipment selection, grind coarseness, water-to-coffee ratio, steeping time, and suitable coffee beans, and compiles several single-origin beans recommended by Front Street Coffee to help you make a cold brew coffee that is refreshing or has a prominent fermented note, according to your taste preference.

Cold brew coffee is divided into two types: cold water immersion and ice drip, both of which use low-temperature water for extraction throughout the process. Large bitter-tasting molecules are not easily released, while sugars and organic acids dissolve more fully, so the mouthfeel is often more balanced. However, bean selection, grind size, coffee-to-water ratio, and steeping time all affect the final flavor. This article takes Front Street Jamaica Blue Mountain No. 1 as an example, first explaining the growing environment and flavor characteristics of Blue Mountain coffee, then sharing the operational details of cold brew: it is recommended to choose light to medium roast single-origin beans, grind slightly finer than for pour-over, steep for 8 to 18 hours, and keep the coffee-to-water ratio at about 1:11. Finally, it gives Front Street's cold brew method to help you make a refreshing and smooth iced coffee. [more…]
