Cold brew is coffee steeped in cold water for 12-24 hours. Iced coffee is hot-brewed coffee poured over ice. Cold brew offers a smoother, lower-acidity, naturally sweet profile. Iced coffee tends to be brighter and more acidic.
Medium-dark roast coffees with chocolate and nutty profiles are ideal for cold brew. Brazilian and Colombian origins are the most popular choices. You can also try light-roast fruity coffees for a different but interesting cold brew experience.
Combine coarsely ground coffee with cold water at a 1:8 ratio (125g coffee to 1L water) in a glass jar or French Press. Refrigerate for 18-24 hours, then filter. Store the concentrate and dilute 1:1 with water or milk when serving.
Cold brew coffee is made by steeping coarsely ground beans in cold or room-temperature water for 12 to 24 hours. Because hot water is never used, the resulting brew has up to 67 percent lower acidity, higher natural sweetness, and a remarkably smooth profile. It is a fundamentally different method from iced coffee, which is hot-brewed and then chilled.
Cold brew is one of the fastest-growing coffee categories worldwide. Low acidity, natural sweetness, and a smooth, gentle profile make it an ideal alternative for people with sensitive stomachs, those cutting back on sugar, and anyone looking for a refreshing way to enjoy coffee on warm days.
Bean selection for cold brew favors low-acidity, naturally sweet, and full-bodied profiles. Medium-roast beans from Brazil, Colombia, and Guatemala produce excellent results. Chocolate, nut, and caramel notes remain rich and satisfying even in a cold extraction.
Preparation is straightforward: combine coarsely ground coffee with cold water at a 1:5 ratio for concentrate or 1:12 for ready-to-drink strength, refrigerate for 18 to 24 hours, then strain. If you make concentrate, it keeps in the refrigerator for up to two weeks — the perfect batch method for grab-and-go mornings.
The fundamental difference between cold brew and hot brewing lies in extraction chemistry. Hot water dissolves many acidic compounds that cold water simply cannot reach. This is why cold brew is naturally smoother and sweeter without any additives.
An extra-coarse grind — even coarser than French Press — prevents over-extraction during the long steep time.
Make a large batch of concentrate at the start of each week. It keeps in the fridge for up to two weeks — instant ready-to-drink coffee every morning.
Low-acidity, naturally sweet profiles deliver the best cold brew results. Stick to chocolate-forward origins for the richest flavor.
“We use Brazilian natural-process beans for our cold brew concentrate — chocolate and nut notes stay rich even at cold temperatures. Mix one-to-one with milk and you have the most refreshing summer drink imaginable.”— Fuga Coffee Brewing Team
