The sunset after the beginning of autumn is exceptionally gentle. Looking up at the sky, the pink-blue sky can heal the fatigue of the day. Gazing at these soft tones always reminds me of foods filled with floral and fruity aromas, such as cotton candy, fruit pies, and, of course, Guanxi coffee.

In the world of coffee, besides the numerous varieties, complex growing regions, and increasingly innovative processing methods, the ways of extracting coffee are also diverse. In this article, FrontStreet Coffee will adopt five brewing methods to experience the gentleness of FrontStreet Coffee's small-bean Guanxi coffee from different perspectives.

V60 Drip Extraction

Flavor Profile: Mixed berry-like aroma, creamy strawberry and passionfruit-like sweet and sour notes, prominent sweetness, and full-bodied texture.

The V60 filter cup gets its name from its 60-degree cone-shaped design. This angle guides water flow to the center, extending the contact time between water and coffee. The large aperture filter hole at the bottom allows everyone to control the coffee's flavor extraction time by changing the water flow rate. To prevent water from passing through the coffee powder layer too quickly, FrontStreet Coffee recommends using a medium-fine grind size (80% passing through a Chinese #20 sieve). To better showcase the full juicy feeling and rich fruit aroma of the small-bean Guanxi coffee, FrontStreet Coffee suggests using a water temperature of 91 degrees Celsius and a three-stage slow circular fine water stream injection technique.

The brewing amount is 15g of coffee powder, with a powder-to-water ratio of 1:15, meaning we need 15g of coffee powder to extract with 225g of hot water. First, use 30g of water for a 30-second bloom, then pour water in a circular pattern from the center outward and back to the center at a flow rate of 4g per second and 4 seconds per circle until reaching 125g. Wait until the powder bed drops to half its height, then continue with the same method to reach 225g. After all the coffee liquid has filtered into the lower pot, remove the filter cup to end the extraction. The total brewing time is 2 minutes and 10 seconds.

Clever Cup Immersion Extraction

Flavor Profile: Mixed berry-like aroma, full-bodied strawberry juice feeling, creamy smoothness, and tea-like aftertaste.

The bottom of the Clever Cup consists of two layers. The outer layer serves as support, while the inner layer features a pressure-activated switch valve. When not placed on a container, the valve remains in a closed state, allowing the coffee powder to steep within. After steeping is complete, simply place the filter cup on a container, and the pressure on the bottom middle will activate the piston valve, allowing the coffee liquid to flow into the container. Since immersion extraction is used, FrontStreet Coffee recommends a medium grind size (75% passing through a Chinese #20 sieve), a water temperature of 90 degrees Celsius, and a central fine water stream injection technique.

The brewing amount is 15g of coffee powder, with a powder-to-water ratio of 1:15, meaning we need 15g of coffee powder to extract with 225g of hot water. First, move the Clever Cup to the electronic scale (at this point, the valve will automatically close), pour the ground coffee into the center of the filter cup. Press the timer, and in the first stage, inject 30g of hot water in a "Z" pattern for a 30-second bloom. After blooming, there's no need to circle; inject hot water with a fine stream in the center of the filter cup until reaching 225g, then let it steep for 1 minute and 50 seconds. After steeping is complete, move the Clever Cup onto the container to open the valve and filter the coffee liquid from the filter cup. This entire process takes approximately 15 seconds, with a total coffee extraction time of 2 minutes and 5 seconds.

French Press Immersion Extraction

Flavor Profile: Mixed berry-like aroma, complex fruit juice feeling, obvious creamy texture, overall full-bodied and mellow.

The French press consists of a heat-resistant glass container and a metal filter with a plunger, mainly extracting coffee through immersion. During the extraction process, the longer the immersion time, the more substances are extracted from the coffee until saturation, meaning the longer it steeps, the stronger the coffee becomes. Meanwhile, the metal filter retains a large amount of oils from the coffee, resulting in a smoother coffee texture, but it cannot completely filter fine particles, creating a slightly gritty feeling. To avoid over-extraction, FrontStreet Coffee recommends a medium-coarse grind size (71% passing through a Chinese #20 sieve), a water temperature of 92 degrees Celsius, and an immersion time of 4 minutes.

The brewing amount is 15g of coffee powder, with a powder-to-water ratio of 1:15. Pour the ground coffee powder into the pot, then add 225ml of hot water. Pull up the plunger, cover with the lid, and wait for 4 minutes. Then slowly press down the plunger until the metal filter reaches 1/4 of the pot's height to prevent fine particles at the bottom from rising to the top.

AeroPress Pressure Extraction

Flavor Profile: Saturated berry fruit sour aroma, prominent sweetness, creamy smoothness, high cleanliness, and obvious tea-like feeling.

The AeroPress structure can be simply divided into three main parts: the chamber, the filter cap, and the piston plunger. It combines the immersion extraction method of a French press, the paper filter of pour-over coffee, and the pressure extraction of an espresso machine. Its working principle is to mix coffee powder with hot water, stir, then use the plunger to push air through the filter cap, extracting coffee with clean flavors. Since it's a short-time pressure extraction, FrontStreet Coffee recommends a fine grind size (90% passing through a Chinese #20 sieve) and a water temperature of 90 degrees Celsius.

The brewing amount is 15g of coffee powder. First, press the circular filter paper onto the filter cap and moisten it with water to make it adhere; then attach the filter cap to the chamber and place it face-up on top of a filter cup. Place the funnel, pour in 15g of ground coffee powder; then start timing, pour in hot water until the water level reaches the "④" mark on the chamber, and use the stirrer to gently stir the coffee powder inside the chamber so that all coffee is moistened by water. Attach the piston plunger; because there will be positive pressure causing coffee to drip into the lower chamber, the action of stirring and attaching the plunger after pouring water should be quick. After attaching the plunger, the dripping will stop because it's in a sealed state. After 1 minute, begin pressing the piston plunger. The coffee liquid is pressed into the lower chamber under the effect of pressure. After pressing is complete, the total time is 1 minute and 20 seconds.

Cold Water Immersion Extraction

Flavor Profile: Complex fruit juice sour aroma, full-bodied berry juice feeling, passion fruit fermentation aroma, balanced sweet and sour, overall full-bodied and mellow.

Cold brew coffee, also known as cold extraction, involves steeping coffee powder in cold water for extraction. The cold brew method can amplify the various flavors and aromas of coffee, reduce acidity, and enhance the overall body of the coffee. Since low-temperature extraction is used, FrontStreet Coffee recommends a medium-fine grind size (85% passing through a Chinese #20 sieve). Room temperature water or ice water can be used for steeping.

FrontStreet Coffee recommends a powder-to-water ratio of 1:15 for making cold brew coffee. For example: 30g of coffee added to 300g of room temperature water and 150g of ice cubes (or directly adding 450g of room temperature water), stir thoroughly and place in the refrigerator to steep for 12-24 hours. After extraction is complete, filter out the coffee grounds using filter paper or a fine mesh sieve before drinking. The optimal tasting time for cold brew coffee is 2-3 days after filtering the coffee grounds, and it's recommended not to store for more than 7 days.
