Cold brew coffee has always been known for its long, low-temperature steeping, often requiring 5 to 24 hours when made with room-temperature water. To shorten the wait, some people have tried steeping coffee grounds in warm water. This article explores the differences between cold-water and warm-water extraction, the reasons why cold brew has lower acidity, and a warm-water cold brew comparison test using Front Street Coffee's Elida Catuai. It records the sensory differences between 3 hours in 45℃ warm water and 7 hours in room-temperature water, and offers bean selection advice and practical tips for warm-water cold brew. [more…]

The joy of pour-over coffee lies in the fact that with the same bean, a different extraction approach can produce a completely different flavor in the cup. Today I'll share a special method called "low-temperature fine-grind slow pour," inspired by automatic cold brew machines—grinding the coffee to a fineness close to espresso, then using low-temperature water to extract slowly. This approach both releases the coffee's flavors more completely and effectively avoids over-extraction. Below, using Front Street. Blackberry as an example, I'll break down the grind parameters, pouring technique, and extraction ratio in detail, compare the flavor with a conventional pour-over method, and include notes from actual practice for coffee enthusiasts to try.

Although cold brew coffee and iced Americano are both iced coffee drinks, the core difference lies in the extraction temperature: cold brew uses low-temperature long-steeping, while iced Americano is hot espresso diluted with water and then poured over ice. Low-temperature extraction reduces the release of bitter compounds while fully preserving the sweet and sour flavors, so cold brew tastes cleaner and fuller; Americano, on the other hand, is rich, bold, and robust. This article explains in detail the brewing principles and flavor differences of the two, and shares a cold brew coffee brewing tutorial, suitable coffee bean choices, and storage period recommendations, helping you understand and make cold brew coffee more professionally.

In pour-over coffee, over-extraction is one of the main causes of bitterness, and the excessive fines produced by underperforming grinders often exacerbate this problem. Front Street Coffee has previously introduced the stepped temperature-decline extraction method to reduce the extraction rate in the middle and latter stages, and this time we'll share using low-temperature water for the blooming stage. Emi, the 2018 WBrC champion, once adopted a low-temperature blooming strategy, using a valve dripper to alternate immersion and drip extraction, with the aim of gently extracting sweetness and avoiding a dry finish. Front Street tested with Ethiopian Hualigui beans, which had a fines rate of 14% when ground with a hand grinder, and produced a lingering dry bitterness after conventional brewing. By adjusting the blooming water temperature to 83°C, extending the blooming time to 35 seconds, and then raising the water temperature to 93°C for subsequent pours, the result was a balanced flavor with rich berry-like sweetness and acidity, a noticeable tea-like aftertaste, and no bitterness. If you've also struggled with over-extraction, you might want to consider this approach. [more…]

Coffee doesn't have to be brewed with hot water—cold water can also extract surprisingly delightful flavors.

In recent years at the World Coffee Brewing Championship, competitors have frequently used low-temperature water for brewing, and even champion brewers have shared similar approaches.
