When faced with a new bean, roasters typically start by gathering origin information and the flavor descriptions provided by the green bean supplier, then gradually adjust through test roasts and cupping. Front Street Coffee Costa Rica Mozart is known for its unique raisin honey process and complex aroma. This article documents the complete roasting exploration process for this bean: first, three test roasts were conducted using a stepwise decreasing heat and extended dehydration approach, but cupping revealed the flavor was rather light; subsequently, three more roasts were done using rapid dehydration and increased heat to drive aroma, and ultimately a curve combining floral notes and fermented winey aroma was selected. The article also includes pour-over extraction parameters and brewing techniques for coffee enthusiasts' reference. [more…]

In coffee roasting, "first crack" is not only an important auditory milestone, but also directly relates to the final flavor presentation in the cup. This article uses Front Street Coffee's Costa Rica Natural Black Soul as a sample, conducting comparative experiments through three roasting curves with different first crack times, to deeply explore the specific effects of the length of the drying phase on bean expansion, the degree of the Maillard reaction, and cupping flavor. From 7 minutes 30 seconds to 8 minutes 30 seconds, subtle differences in first crack timing bring significant changes in fruit acidity, sweetness, body, and complexity. This article will break down each curve's roasting parameters, bean surface condition, and brewing performance one by one, helping roasting enthusiasts understand the core logic of first crack time control.

Roasting is the key stage that determines the direction of coffee flavor; the same green beans will present completely different aromas and tastes under different roast levels. Starting from the roasting practice of FrontStreet Coffee, this article systematically sorts out the complete roasting process of coffee beans from bean charging, dehydration, first crack to second crack, explains the specific flavor performance of light, medium, and medium-dark roast levels in cupping, and introduces the Agtron color value as a scientific judging standard. Taking sun-dried Yirgacheffe as an example, the article provides the yellowing point, first crack temperature, development time, and drop temperature data for three roast levels, and also lists Front Street's representative bean list for each roast level, including Blue Mountain No. 1, the Mandheling series, etc., to help enthusiasts build a corresponding understanding between roast level and flavor.

More and more friends are now joining the ranks of pour-over coffee enthusiasts, and with so many coffee beans to choose from, many are once again struggling with choice paralysis. Generally speaking, the coffee beans used for pour-over coffee are single-origin beans. Single-origin beans refer to beans from a single region (from one estate/cooperative, or from multiple estates/cooperatives within a single origin). [more…]

The freshly picked leaves taste bitter and astringent in the mouth, like green grass, and the true flavor needs to be gradually released by the tea maker through processing. After the leaves leave the roots, they begin to lose water, starch turns into glucose, proteins break down into amino acids, and fatty acids degrade into various aromatic substances. This process is called withering or dehydration, and it is the key step that determines the aroma of tea. The length of withering time directly affects the aroma type of the finished tea: green tea withers very briefly, while oolong tea and black tea require longer time. Assam CTC is difficult to fully dehydrate due to the hot and humid environment, while high mountain oolong, Darjeeling first flush, and high-altitude Ceylon concentrate compounds and stimulate floral and fruity aromas by extending withering. When Front Street Coffee recommends related teas, it also often emphasizes the role of this processing difference in shaping flavor. [more…]
