American Style Pour-Over Coffee

Have you ever tried coffee brewed with an American-style pour-over? You'll notice that with the same coffee beans, American-style pour-over produces coffee that is noticeably more bitter and astringent compared to hand-pour brewing. The key factor is the high water temperature in American-style brewing. Generally, American-style brewers actually extract by spraying water through atmospheric pressure.

Simply put, when the power of an American-style brewer remains constant and external environmental factors don't vary much, the extraction water temperature and flow rate remain relatively stable. However, this extraction temperature is too high and the flow rate is too slow, leading to over-extraction. This is where the bitterness and astringency come from - Americans prefer this type of bitterness.

Differences Between American and Japanese Styles

Although American and Japanese styles might use the same type of filter cup, there are differences in coffee bean roasting, grinding, filter paper, water temperature, and techniques.

The biggest difference is that American-style pour-over requires stirring the coffee grounds with a stir stick while pouring, somewhat similar to the stirring technique we use with siphon brewers. In contrast, Japanese, Korean, Taiwanese, and domestic hand-pour coffee only uses water to pour in circles, never using stir sticks or bamboo to stir the coffee grounds.

Typical American flavor profiles mainly feature medium and dark roasts, with richness + mild bitterness + sweetness. It combines both bitterness and sweetness characteristics. For medium roasts, use medium grinding, water temperature between 80-85°C, and medium pouring speed. For dark roasts, use fine grinding, water temperature between 85-90°C, and slow pouring with fine water flow, resulting in heavier bitterness. Americans often drink a cup in the morning to quickly wake up, hence it's also called "dawn coffee."

American Brewing Method

American brewing is relatively simple.

First, the grounds should be ground very finely, basically similar to espresso grinding;

Second, water temperature should be around 90°C;

Third, blooming is similar to the Japanese style;

Fourth, while slowly pouring water in circles, continuously stir with a wooden spoon or bamboo stick. There are different stirring techniques: one is back-and-forth horizontal stirring; the other is circular stirring.

Japanese Brewing Method

Light and medium roasts + coarse grinding, with a fast pouring method using 86-92°C water, is the method preferred by Eastern ethnic groups, focusing on and pursuing the balance between acidity and bitterness.

Another issue that often causes confusion is the difference between filter-immersion and drip brewing (or more accurately, drip-style brewing).

What is "filter-immersion"? It refers to small-hole filter cups like Melitta. Their filter cup holes are very small, and whether one-hole or three-hole, their dripping speed is relatively slow. The coffee grounds are actually fully immersed and extracted by hot water at a certain temperature, so medium-dark roasts work better.

What is "drip-style"? V60 and other large-hole conical filter cups, flannel filters, Swiss Gold and other metal filters can all be categorized as drip-style. Their common characteristic is large and unobstructed bottom holes, where the dripping speed is determined by the operator's pouring speed, so they can adapt to any type of roast.

Personal Recommendation

The most commonly used method, also the most stable and convenient, with balanced flavor. Personal recommendation: 20g of coffee with a 1:15 water ratio.

1. Wet the coffee with about 30g of hot water.

Shake the filter cup to even out the powder, use your finger to create a hole in the center, and pour in a zigzag pattern from the center position. Don't let water touch the filter paper edge. When the "hamburger" shape appears, start timing from when you begin pouring.

2. After beautiful blooming, complete the pouring within the next 2.5 minutes.

Around 50 seconds, perform zigzag pouring from inside to outside in a circular pattern, ensuring the water stream doesn't touch the filter paper. After significant blooming, complete the first pour around 1 minute and 10 seconds. Wait for the water level to drop significantly before the second pour. After significant blooming again, pour once more. Continue this cycle until reaching the desired water amount, then stop immediately. The entire hot water drip process should complete in approximately 2-2.5 minutes.
