Front Street often says that coffee is like food, with various "cooking methods"! Even if it is the same bean, under different extraction methods, the coffee it presents will have a completely different feeling! So today Front Street will take stock of some common extraction methods in coffee making~
trickling filter
Extraction method: This is the most commonly used extraction method when we make single-origin coffee! As the name suggests, "drip filter" refers to an extraction method that continuously injects hot/ice water into the coffee powder layer under normal pressure to extract the aromatic substances inside and drip filter it into the lower pot at the same time!
Extraction characteristics: Due to the extremely excellent filtering performance, the extracted coffee is usually very clean! Especially suitable for light-medium roasted coffee beans with mainly floral and fruity aroma! Moreover, it can also be paired with immersion to extract coffee with a fuller and thicker taste!
Extraction applicable: Pour over(V60) coffee, iced drip coffee, American drip filter machine, hanging ear coffee
What is hanging ear coffee?
As the "instant noodles" in the coffee world, black coffee can be obtained by pre-grinding coffee beans into powder, putting them into a filter bag with "ears" according to a fixed weight, and then pouring hot water and separating the grounds. Whether you are in the office, in the park, on a train or on a plane, as long as you are equipped with a cup and hot water, you can enjoy coffee freedom anytime and anywhere. Without a doubt, this is the easiest type of drip coffee.
Hanging ear coffee bags are drip extraction, and their design is derived from hanging tea bags. The inventor hopes to simulate Pour over(V60) drip coffee by preparing the coffee powder in advance and putting it into a non-woven filter bag. The paper pieces on both sides of the filter bag can suspend the coffee bag in the center of the cup.
Since the coffee beans are pre-ground and there are no various brewing auxiliary equipment, the aroma may be slightly lacking, but because the filter bag is fine, the brewed coffee tastes cleaner and clearer. But what everyone is interested in is actually the "simplification" of the ear-mounted earphones, which allow us to quickly and conveniently get a cup of drip black coffee in our daily life.
The amount of water to pour into ear-hanging bags is relatively easy to determine. For example, the ear-hanging bags in former street stores are 10 grams per small bag. Follow the hand-made powder-to-water ratio of 1:15 to 1:18. It is recommended to inject 150-180ml of water.
Usually, you first pour a small amount of hot water into the ear-hanging filter bag to moisten the coffee powder. Pour the first part to 1/2 of the filter bag and simmer for about ten seconds. Then pour water into the center twice in a row until the ear-hanging bag is 80% full. After all the coffee liquid in the filter bag has dripped out, continue to add water until the last section of filtering is completed. If the water is filled until it is full, the water accumulated in the upper layer will easily bypass the "powder layer" and filter out directly from the side of the ear-hanging bag, resulting in a weak coffee taste.
After several tests, Front Street injected water in three stages, which took about one and a half minutes, and the total water injection volume was basically around 150ml. If you want a lighter taste, add a little more until it is 80% full, so it will be about 180ml.
Recommended hanging ear coffee: Mixed flavor hanging ear from the five Front Street production areas (Honduras, Kenya, Ethiopia, Panama, Indonesia).
Immersion
Extraction method: "Immersion" uses a relatively large amount of water to soak the coffee powder to a certain extent. The time can be long or short. Compared with the drip filter, it is subject to fewer artificial influences and is easier to present the taste of coffee itself! Therefore, the evaluation of coffee beans is generally based on immersion cupping!
Extraction characteristics: As mentioned in the introduction, it is the extraction method with the smallest human influence! Adding immersion, or using immersion extraction, the coffee will have a higher body and a more uniform taste, and the flavor of the coffee can be more completely presented.
Suitable for extraction: smart cup, cold brew coffee, French press, Aeropress, some Pour over(V60) coffee, etc.
Recommended coffee beans: floral flavored Front Street Dingding, cherry tomato flavored Front Street tomatoes, passion fruit flavored Front Street Xizhao
Pressurized
Extraction method: In the production process, there is not only powder and water, but also pressure is added for extraction. In this way, the coffee powder substances will be quickly dissolved due to the pressure. In addition to the flavor substances, the carbon dioxide hidden in the coffee beans will be "forced out" due to the huge pressure, forming a layer of golden foam with the fat (which is what is mistranslated as oil) floating on the surface of the coffee!
Extraction characteristics: The extraction process is very fast, and the coffee that comes out is very rich, with golden oil and a very mellow taste! You can use it as a base to create so many different types of coffee!
Suitable for extraction: Moka pot, espresso machine.
Recommended coffee beans: Front Street Classic Blend, Front Street Black Cocoa Basic Blend, Front Street Commercial Blend, Front Street Premium Blend
siphon type
Extraction method: This extraction method is only used on siphon pots! The steam generated by heating water creates pressure to push the hot water in the lower pot to the upper pot, thereby extracting the coffee powder in the upper pot! After the lower pot cools down and the pressure is gone, the hot water from the upper pot will return to the lower pot with the flavor substances in the coffee!
Extraction characteristics: The coffee extracted with a siphon pot has a mellow taste (with a certain soaking effect) and a clean flavor! Moreover, because the design of the siphon pot is full of steam colors, in addition to the coffee drinking experience, it is also highly ornamental!
Suitable for extraction: siphon pot.
