If the brewed espresso isn't finished on the same day, can it be safely stored in the fridge or freezer overnight and still be enjoyed the next day? Beyond food safety concerns, what coffee lovers really care about is whether the flavor will take a serious hit. Front Street Coffee used the same espresso blend, storing espresso in the refrigerator and freezer overnight respectively, then comparing them with freshly brewed espresso—tasting each as straight espresso, Americano, and milk coffee—to see just what overnight coffee turns into, and how big the gap is between freezing and refrigerating.

Why can't you drink ice drip coffee immediately after it's made? What exactly is the difference between it and cold brew? This article provides a detailed explanation of ice drip coffee's shelf life, the principles of flavor maturation, and its brewing parameters and ratios. Freshly dripped ice drip coffee has a flat flavor and needs to be sealed and refrigerated for more than 8 hours to mature before it can present a mellow, silky mouthfeel and its signature wine-like aroma. It can be kept refrigerated for 3 to 5 days, but after more than three days the fermented taste becomes noticeably stronger, so Front Street sets the optimal drinking period at 3 days. The article also includes the ratio parameters for making ice drip, helping you fully master this coffee that requires patient waiting. [more…]

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.

To create beautiful and long-lasting latte art patterns, the choice and handling of milk actually matter a great deal. Whole milk, because of its higher fat and protein content, makes the milk foam more stable and fine; keeping the steaming temperature below 70°C avoids the negative effects of lactose caramelization and protein denaturation; refrigerated storage extends the frothing time, making the foam denser and creamier. Drawing on years of experience, Front Street Coffee recommends using freshly roasted medium-dark roast espresso blend beans as the base, and shares two products suitable for beginners: the Front Street Dark Cocoa Blend and the Front Street Strawberry Candy Espresso. This article will explore these three dimensions, explaining why latte art has these requirements for milk, to help you create your ideal patterns at home. [more…]

Black tea and green tea share the same origin yet have vastly different flavors, and the fundamental difference lies in the degree of oxidation during processing. Black tea undergoes complete oxidation, presenting honey, caramel, and ripe fruit aromas; green tea, through fixation (kill-green), retains its fresh green character, with a light flavor carrying bean or nutty notes. The two teas also differ greatly in storage: green tea, due to its high moisture content and tendency to continue oxidizing, is best stored sealed and refrigerated; black tea is dry and stable, and can be kept sealed at room temperature for over a year. This article systematically sorts out the similarities and differences between black and green teas such as Lapsang Souchong and West Lake Longjing from four dimensions—tea plant varieties, production processes, storage key points, and taste characteristics—and includes Front Street Coffee's purchasing and preservation suggestions to help you better understand the tea in your cup.

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.
