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…]

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. In fact, this isn't truly cold water, but a variable-temperature brewing method using water cooler than conventional hot water—extracting coffee in stages with multiple water temperatures to regulate the speed and amount of soluble compounds dissolving, thereby achieving the ideal flavor. This article shares three common and practical variable-temperature brewing methods: the bloom variable-temperature method, the final-stage variable-temperature method, and the immersion variable-temperature method. Using Panama Geisha and Finca La Frontera Sidra as examples, Front Street provides detailed parameters such as water temperature, grind size, and coffee-to-water ratio to help you easily try it at home.

Elida Estate is renowned for its sun-dried processing, and this ASD Geisha shines in fermentation aroma, juicy mouthfeel, and layered tea-like notes. Below, we share four specific brewing recipes and comparison results for coffee enthusiasts' reference. [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.

In pour-over coffee, when extraction parameters are too high, it is usually possible to dial them back, but if over-extraction is caused by too many fines from the grinder, adjusting parameters alone is often not enough to solve the problem. In this case, sifting out the fines or adopting variable-temperature brewing are both response options recognized by Front Street Coffee. This article will focus on variable-temperature brewing: it is not a minor adjustment of 2~3°C, but rather segmented extraction with a larger temperature differential, controlling the dissolution rhythm of flavor compounds through high-temperature fast extraction and low-temperature slow release. The article will trace the origins of this method, analyze the championship cases of Wu Zelin and Emi, explain how to use cold water to regulate temperature and achieve a variable-temperature operation that starts high and ends low, and share in detail the practical process of the "Devil Brewing Method" by Tetsu Kasuya, which Front Street Coffee favors.

Cold brew coffee usually requires 8 to 12 hours of low-temperature slow extraction, but what if you want to drink it the same day? Raising the water temperature can speed up extraction, but if you use hot water directly, it becomes hot brew, and the floral and fruity aromas and low bitterness unique to cold brew will also disappear. Front Street compared three methods through experiments: conventional 23°C cold water extraction for 10 hours, 40°C warm water extraction for 4 hours, and 92°C hot water blooming followed by room-temperature water extraction for 4 hours. The beans used were Colombia · Hanami, with full berry acidity, floral notes, and pink pepper flavors. The results showed that the 40°C warm water rapid cold brew was closest to the performance of conventional cold brew, with both a fermented feel and clearly presented flavors, making it suitable for friends who want to drink cold brew quickly.

Ice drip coffee and iced pour-over coffee are often mentioned together, but the two differ significantly in extraction principles, flavor expression, and brewing process. Ice drip is a low-temperature slow extraction, while iced pour-over is a high-temperature fast extraction followed by cooling. Temperature greatly affects the breakdown rate of oils, acids, and sugars in coffee, thereby shaping distinctly different aromas, mouthfeels, and layers. From the perspective of Front Street Coffee, this article systematically sorts out the respective characteristics of high-temperature extraction and low-temperature extraction, and, using Honduras Sherry coffee beans as an example, records in detail the brewing parameters and flavor comparison of ice drip and iced pour-over, helping coffee enthusiasts more clearly understand the essential differences between the two kinds of iced coffee.

The most delightful thing in summer is nothing more than staying at home with the air conditioning on and drinking a cup of homemade cold brew coffee. Cold brew uses low-temperature extraction throughout, which is completely different from iced pour-over or iced Americano, where hot water is used first and ice is added afterward. Low temperatures suppress the release of bitter compounds, but they also lengthen the extraction time, generally requiring 6 to 12 hours. This article will explain the relationship between the extraction principles of cold brew and the flavor composition of coffee beans, explain why increasing concentration actually requires coarsening the grind, provide a specific method using 30g of coffee, a 1:13 coffee-to-water ratio, and 8-12 hours of refrigeration, and sort out three types of beans suitable for cold brew: light roast, fermented flavor, and dark roast, with a key response to whether Mandheling is suitable, while also noting that choosing coffee beans rested for more than 10 days is better for aroma expression. [more…]
