The Impact of Blooming and Its Duration on Pour-Over Coffee (Part 2)
Last time, we used the Clever dripper to obtain objective data about blooming and its duration. We learned from sensory evaluation that as blooming time increases, acidity decreases while sweetness and viscosity are enhanced. The overall flavor profile gradually shifts toward the backend and becomes more complex. From the TDS and EXT readings, we observed that as blooming time lengthens, both TDS and EXT values show a downward trend. And I...

The Impact of Blooming and Its Duration on Coffee Brewing (Part 1)
We've conducted numerous experiments sporadically in our shop, but never organized the results systematically. Over time, many of the theories and experimental findings we discovered have faded from memory. Therefore, FrontStreet Coffee's team decided to conduct rigorous experiments with minimized deviations, and organize the data and results to share with everyone, helping us remember better and allowing everyone to benefit together.

What is Pre-infusion? Understanding Pre-infusion Principles and Methods, and Duration
Whenever developing an extraction framework for pour-over coffee, we always include the pre-infusion step by default. An ideal pre-infusion allows carbon dioxide to be released in an orderly manner while "awakening" the soluble substances in the coffee, making subsequent flavor extraction more stable. Since pre-infusion has such a significant impact on coffee flavor, what about other brewing methods?

Coffee Basics: Pour-Over Brewing Time & Typical Extraction Duration
FrontStreet Coffee has noticed that many beginners when first starting with pour-over coffee pay great attention to brew amount, coffee-to-water ratio, water temperature, technique, and grind size, but take a casual approach to extraction time—this won't do! Extraction time is extremely important! Why is extraction time so crucial? Only 30% of a coffee bean consists of soluble flavor compounds, while the remaining 70% is woody fiber,

How to Appreciate the Aftertaste of Pour-Over Coffee? Why is Espresso Crema So Aromatic? What is the Coffee Tasting Process?
We evaluate coffee from multiple perspectives: aroma, mouthfeel, flavor, aftertaste, and more. In fact, this applies not only to coffee but also to other beverages like tea and wine. However, many coffee enthusiasts tend to focus primarily on aroma and flavor perception, completely overlooking the aftertaste experience, unaware that aftertaste plays a crucial role in the overall coffee appreciation.

Sun-Dried, Washed, Honey Process - All These Coffee Post-Processing Methods Actually Involve Fermentation!!
The "processing" of coffee beans refers to the operation of removing impurities from coffee cherries (everything except the raw beans) and turning them into coffee beans. At the same time, it is also an important step that can influence the flavor direction of coffee beans. Among these, anaerobic fermentation processing methods have been a controversial coffee processing approach in recent years.

How Long Do Coffee Beans Last After Grinding? Why Is It Better Not to Pre-Grind Coffee Beans? What's the Difference Compared to Fresh Coffee?
For many home coffee brewers, a grinder is not an essential item, so they often choose the grinding service offered by coffee merchants.
