Front Street-Coffee Technique, Blue Mountain Coffee Flavor Introduction

Fractional extraction: After steaming, a section of water is injected in several sections, suitable for light, medium and light roasted coffee beans.

Advantages: More rich than a knife flow layer, can be clear coffee before, during and after the flavor. The practice is to increase the amount of water injected each time after steaming, usually when the coffee liquid is about to fall to the surface of the powder layer, and to do three-stage extraction with small, medium and large water flows.

Disadvantages: There will be relatively high requirements for water flow rate and flow rate.

The so-called segmented extraction is divided into several sections of water injection, in the segmented extraction of the most famous than the three-knife flow, segmented extraction also belongs to a knife flow extension of a brewing method, segmented extraction can make the coffee powder wall at the edge of the filter paper is not easy to be broken, and segmented water injection also helps to increase the coffee powder in the brewing stirring, water injection flow can penetrate the coffee powder to improve the extraction rate.

Blue Mountain coffee is coffee brewed from coffee beans grown in the Blue Mountains of Jamaica. The Blue Mountains are located in the eastern part of Jamaica Island. They are named because they are surrounded by the Caribbean Sea. Whenever the weather is clear, the sun shines directly on the blue sea, and the peaks reflect the bright blue light of the sea. The highest peak of Blue Mountain is 2256 meters above sea level, which is the highest peak in the Caribbean and a famous tourist attraction.

It is located in the earthquake zone, with fertile volcanic soil, fresh air, no pollution, humid climate, foggy and rainy all year round, average precipitation of 1980 mm, temperature of about 27 degrees, such terroir conditions have created the world-famous Jamaica Blue Mountain Coffee, but also created the world's second highest price coffee. This kind of coffee has all the characteristics of good coffee, not only the taste is rich and mellow, but also because the sweet, sour and bitter flavors of coffee are perfectly matched, so there is no bitterness at all, only moderate and perfect sourness.

Both Front Street and other coffee shops are keen to use this technique because it allows for staged adjustments during brewing, so that coffee extraction can avoid under-extraction and over-extraction problems. Today, Qianjie will use Blue Mountain to do a segmented extraction to see if it can achieve a perfect balance of sweet, sour and bitter in a rich taste.

Hand washing parameters: 15g powder, kono filter cup, water temperature 86℃, powder water ratio 1:15, grinding degree BG 6W (medium coarse grinding).

Method: Steam with 30g water for 30 seconds, inject water evenly into 125g sections with small water flow, continue to inject water to 220g when the water level drops and is about to expose the powder bed, remove the filter cup when the powder bed is about to be exposed, do not use 5g water at the end, start steaming and time extraction time is about 1 minute and 50 seconds.

Flavor: Vivid aroma, balanced alcohol/acidity, round taste, lingering finish.
