Cold brew coffee is highly favored in summer. It is usually made by steeping coffee in the refrigerator overnight using a coffee filter, and can be prepared by either pour-over or drip methods. It takes about 12 to 18 hours, yet the flavor is quite excellent. Many people believe that iced coffee is better than hot coffee, like a dessert in a glass. With ice cubes, coffee, flavored syrup, and dairy products combined, the result is amazing, and it can easily be made at home. When making it, you should choose high-quality coffee beans. Front Street Coffee's dark-roasted Brazil and Mandheling coffees are both good choices. The type of ice also matters. Crushed ice, medium ice cubes, and large ice cubes each have their own suitable uses. As for whether leftover cold brew can be stored in the refrigerator, the answer depends on the type of coffee and the storage method. Cold brew can be refrigerated for 2 to 3 days, while drip iced coffee is best kept for no more than 24 hours. [more…]

As the Spring Festival approaches, courier services are gradually suspending operations, and many coffee lovers have already stocked up on beans in advance. But how to keep coffee beans fresh during this period has become a concern for everyone. Storing coffee beans requires avoiding three major enemies: high temperatures, moisture, and oxidation. High temperatures accelerate the loss of aroma, moisture easily leads to mold, and oxidation shortens the optimal flavor period. Front Street recommends that unopened original packaging be kept in a cool, dry place, and that an airtight container be used after opening. As for refrigeration or freezing, although it can slow oxidation, it comes with the challenges of absorbing odors and becoming damp during thawing. This article will break down these storage points in detail to help you enjoy the New Year with peace of mind. [more…]

When the southern "hui nan tian" (return of the damp) arrives, everything at home feels wet, and coffee beans are no exception—they too risk absorbing moisture and growing mold. If you want your pour-over coffee beans to last longer without their flavor fading, the way you store them becomes especially critical. This article centers on how to store coffee beans so they keep longer, starting with the real frustrations of Lingnan's humid climate, analyzing the pros and cons of common practices such as airtight canisters and refrigerator chilling, and warning about the fatal impact of fridge odors on coffee beans. It also draws on the product characteristics of Front Street Coffee to offer storage suggestions better suited to daily life, helping coffee lovers extend their beans' peak flavor period as much as possible in a humid environment.

Cold brew coffee was originally invented to make coffee last longer. Extracting with cold water does not draw out large amounts of coffee oils the way hot water does, so if stored properly in the refrigerator, it can keep for a month without any problem. After three days of aging, the flavor becomes even mellower. However, cold water extraction takes a very long time—common methods can even require dripping for more than 24 hours—and the caffeine concentration is relatively high. In fact, when making it at home, using room-temperature water instead of ice water works just as well and can shorten the time. This article will explain in detail the complete cold brew process, including sterilizing equipment, choosing grind size, the coffee-to-water ratio, controlling drip speed, and how to prevent refrigerator odors from affecting the coffee's flavor, helping you make a rich and aromatic cup of cold brew coffee.
