The difference of filter cup material

With the development of boutique coffee market, hand-brewed coffee has become the apple of many baristas' eyes. Various baristas use a variety of extraction methods to absorb a variety of coffee charm. And a variety of hand coffee tools show the personality and characteristics of different coffee producing areas.

In China, more and more people begin to brew coffee by hand at home, so they no longer have to go to coffee shops to drink. Ordinary coffee lovers can also make high-quality hand-brewed coffee at home.

BlackWaterIssue will share the knowledge and skills of hand-made coffee with readers through the series "COFFEE BREWING".

The first article is "the difference of filter cup material".

Test condition

Filter cup: Hario V60 (2cup)

Coffee: coffee is made by Aricha in Ethiopia and washed by Gaitania in Colombia

Ratio: coffee 15g + water 260g

Cooking method

15g coffee ▷ 45g/20s/ pre-soak ▷ and pour water until 260g, then stir with a stick (4 times per second)

Each sample was determined by TDS for 3 times.

■ Ethiopia Aricha sun

Ceramic filter cup

TDS: 1.27%

Yield: 20.57%

Fragrance: balance, weight, short finish

Glass filter cup

TDS: 1.14%

Yield: 18.44%

Aroma: weaker aroma, more complex aroma, clean, balanced

Metal filter cup

TDS: 1.15%

Yield: 18.60%

Aroma: increased sour taste, complex aroma, lighter weight

Plastic filter cup

TDS: 1.27%

Yield: 20.57%

Aroma: heavy, clean, sharp sour taste

It is worthy of Ethiopia in the sun, showing a good taste, sweetness and fragrance under different materials. However, there are obvious differences between TDS and yield.

The yield of ceramic and plastic filter cup is the highest, which is 57%. Metal is 1.15%, glass is the least 1.14%.

But if you look at the fragrance, glass and metal are more likely to make complex fragrances than ceramics and plastics with high yields.

■ Columbia Gaitania washing

Ceramic filter cup

TDS: 1.31%

Yield: 21.22%

Fragrance: weight, short finish

Glass filter cup

TDS: 1.28%

Yield: 20.73%

Aroma: complex aroma, sweetness, cleanliness, lighter weight

Metal filter cup

TDS: 1.27%

Yield: 20.56%

Aroma: sweet, sour, complex aroma, lighter weight

Plastic filter cup

TDS: 1.30%

Yield: 21.06%

Aroma: weight, sharp acidity, dryness

The yield difference between ceramics and plastics is not obvious, but the yield of ceramics and plastics is still high.

Gaitania, with a good balance and clean fragrance, shows different fragrances on different materials.

Conclusion

Of course, with the change of environmental factors such as coffee type, extraction method, bean grinder and water, the taste will show different taste, but the following conclusions can be drawn from two coffee with different personalities.

Ceramic filter cups are suitable for a richer sense of weight.

Glass filter cup is suitable for more complex fragrance, cleanliness and balance.

Metal filter cup is suitable for stronger sour and sweet taste.

Plastic filter cup is suitable for showing richer sense of weight and cleanliness.

The reason for this difference may be that each material has different heat absorption and heat preservation capacity. And the size of the Rib of the filter cup will also affect the results. Therefore, in order to show the desired taste, we also have to consider the material of the filter cup.
