Here's the thing: when customers push open the front door of Front Street Coffee and step inside, their attention is immediately drawn to the blackboard beside them. There's nothing particularly special on the blackboard—just the new product recommendations and the words "Cold brew coffee requires a 2-day advance order."
As a result, many customers ask upon seeing it, "Is there no cold brew coffee available right now? Do I need to make a reservation?" Actually, whenever the weather gets a bit hot, Front Street Coffee prepares cold brew coffee in advance. However, Front Street typically prepares several coffee beans with broad appeal. If you want cold brew made from a specific coffee bean, you need to order it 2 days in advance.

If you order on T+0 and production starts on T+1, the cold brew coffee bean production takes about 6 hours. But once the cold brew is dripped, Front Street doesn't serve it to customers right away. Instead, the coffee liquid is poured into a sealed glass bottle and refrigerated for more than 8 hours. Only after that can it be served to customers. The timing works out to exactly T+2 days.
Why can't freshly dripped cold brew coffee be consumed immediately?Front Street should clarify here: freshly dripped cold brew coffee can be consumed immediately, but its flavor and mouthfeel are not ideal (not that it tastes bad, but that it doesn't reach the expected level of deliciousness). That's why few coffee shops serve cold brew coffee right after dripping.
Generally, after cold brew coffee finishes dripping, it's bottled and placed in the refrigerator for "aging." Aging can be roughly understood as sealed low-temperature fermentation. Sealing prevents contamination from external bacteria, while low temperature effectively inhibits the reproduction rate of bacterial colonies and also slows down the fermentation process, keeping it in a controllable state.
Freshly dripped cold brew coffee has a relatively thin mouthfeel, and its flavor is more about the coffee bean's original notes—somewhat similar to iced pour-over coffee. But when cold brew coffee is sealed and aged in the refrigerator for 8 hours, its mouthfeel becomes cleaner, mellower, and fuller, with a sweet, rich fermented quality. Some people call this the "cold brew taste."Of course, the fermentation process of cold brew coffee cannot be interrupted—meaning the longer the cold brew sits, the stronger the fermentation. But cold brew coffee doesn't taste better the more fermented it is. Also, frequently opening the bottle cap of cold brew coffee makes it easy for external bacteria to invade, and over time, the coffee will spoil and become undrinkable.
Therefore, cold brew coffee also has a drinking window. Generally, cold brew coffee stored in the refrigerator for 5 days is relatively safe; cold brew coffee beyond 5 days tends to develop off-flavors like sourness from spoilage. Front Street only sells cold brew coffee within 3 days. Although cold brew coffee beyond 3 days won't necessarily spoil or taste bad, out of consideration for flavor experience and health safety, Front Street sets the best-tasting period for its cold brew coffee at 3 days.
Next, Front Street would like to recommend a few coffee beans that are perfect for making cold brew and cold extraction coffee.- Front Street Coffee · Ethiopia TOH Champion Floral
If you like refreshing coffee, then this Ethiopian coffee bean is definitely for you! This Front Street Floral coffee bean actually has quite a pedigree—it's the champion bean of the 2020 TOH washed group, from the Uraga sub-region of Guji. Front Street often uses this bean to make cold brew coffee: 60g of coffee grounds dripped over about 6 hours to produce 600ml of coffee liquid, then refrigerated and fermented for 12 hours before drinking. Add 50g of ice cubes to a cup, then pour in 200ml of coffee liquid.
The cold brew coffee made from Front Street Ethiopia Floral has a faint floral honey aroma and cold brew fermentation aroma on the nose. On the palate, it shows clear citrus and pomelo acidity, honey sweetness, and a green tea finish—refreshing and comfortable.
- Front Street Coffee · Kenya Asalia
Front Street Kenya coffee beans are also very suitable for making iced coffee like cold brew and cold extraction. Thanks to Kenya coffee's excellent acidity varieties (SL28, SL34) and its unique K72 washed processing method, the coffee's acidity is bright and solid with a round mouthfeel. The resulting cold brew coffee offers a completely different experience compared to Ethiopian coffee beans.
Front Street Kenya Asalia coffee beans come from the Honey Processing Plant in the Thika region.
