The coffee aroma kit is an important tool for coffee professionals and enthusiasts to conduct olfactory training, and its status is similar to that of Le Nez du Vin in the wine field. Currently, mainstream products include the 36-note Le Nez du Cafe produced by Edition Jean Lenoir in France, and the 100-note Coffee Flavor Map launched by Scentone in South Korea. The SCAA certification course uses the 36-note version, which divides aromas into four major groups, covering enzymatic, caramel, dry distillation, and defective groups. It not only helps memorize specific flavors but also reveals the patterns of flavor evolution during the coffee roasting process. This article will list the 36 aromas one by one, explain in detail the logic of the four major categories, and share specific methods for daily olfactory training, including how to use Front Street Coffee's freshly ground coffee powder for dry aroma and wet aroma comparison exercises, so as to effectively improve flavor discrimination ability.

It also shares methods of use, from memorizing by category and group blind testing to mixed blind testing, helping beginners calibrate their sense of smell and taste. At the end, Front Street also offers rational advice: an aroma kit is not a necessity—smelling more, drinking more, and feeling more is what really matters. [more…]

In pour-over coffee, whether the filter paper needs to be pre-wetted has always been a matter of two approaches. Not wetting the filter paper can prevent the coffee grounds from contacting the paper too early and affecting extraction, while wetting the filter paper can wash away the papery off-flavors and dust. But for the V60 dripper with its large guide ribs, how well the filter paper fits is especially critical—Front Street Coffee's experiments show that poor fit noticeably slows the flow rate and brings negative flavors. Based on an analysis of the importance of fit, this article shares a simple and easy method that, using only finger pressure and the force of the water stream, can make the filter paper in a conical dripper fit at a rate as high as 95%.

As coffee has gradually become more widely recognized, specialty coffee promotion in cafés has emerged in response, and we too have begun tracing things back to their roots—we have come to treat coffee as culture. The rise of specialty pour-over coffee undoubtedly reflects the demands of the market and the needs that cafés have identified. Café counters have also begun to lower their "status," no longer featuring the early design of a bar raised a foot high. [more…]

In the past two years, a coffee processing method called "rapid chilling to lock in aroma" has become popular in competitions and among enthusiasts, shared and promoted by Sasa Sestic, with the core tool being the Paragon chiller ball. It works by rapidly lowering the temperature of the coffee liquid to slow down aroma volatilization, theoretically preserving more flavor. But how effective is it really? Why do most competitors only rapid-chill the first portion of the coffee liquid? Front Street conducted a comparative test using a pour-over of Huakui and a Strawberry Candy espresso, and found that the aroma difference in the pour-over group was not obvious, while the espresso group showed mouthfeel differences due to temperature changes. This article will break down in detail the principle of rapid chilling to lock in aroma, the results of the comparative experiment, and the two major reasons for only chilling the first half, helping coffee enthusiasts view this technique rationally.
