Coffee filler

Tamper

Coffee filler (Tamper) is an important tool for coffee shop staff to extract espresso. In addition to the appearance of many different materials, the grip, weight, diameter and thickness also have a variety of delicate settings to meet the needs of coffee people. At present, the fillers on the market are roughly divided into six categories: Flat, C-Flat, Ripple, C-Ripple, Curve and Eruo Curve. This time we visit the collector Huang Jijun, who will focus on the plane of the filler and explain the characteristics of the flavor extracted by different fillers. And how novice players should choose the first filler.

Huang Jijun suggested that beginner friends can choose a flat filler to practice their feel, focusing on the smooth filling of coffee powder, solid structure, no tilt angle, and if the planar filler is not proficient in using a filler with a guide angle or curved surface, it will make the packing more uneven because of the imperfection of the technology, which will affect the extraction results.

For players who have reached the advanced model, he suggests buying at least 2 fillers, which can have American arc and European arc to compare the difference of extraction. As for the strength of filling, light filling can bring out the flavor level of aroma and fruit acidity and sweetness, while heavy filling can extend a thick and full-bodied feeling.

The picture on the right shows the general C-Flat, and the picture on the left shows the modified C-Flat of Maruyama Coffee in Japan. The more circular guide angle emphasizes the aroma and soft acidity.

The acidity, sweetness and bitterness of the plane filler show a moderate balance.

A curved filler with a high convex mountain in the middle will show a concave valley in the opposite direction when filling the powder.

The filler of Mei Arc can extract more sweetness and fruit acid, which is suitable for shallow coffee beans.

European arc can extract deeper layers, such as caramelized aroma, Body is also thicker, more suitable for medium and deep culture of coffee beans. If you want to show aroma and acidity, push flat bottom and ripple.

Corrugated packing surface

Huang Jijun said that when choosing a filler, if it is distinguished by radians, RB is recommended by Mei Arc, which is comfortable and durable to operate. It claims to be durable for 20 years without oxidation, but the price will be relatively high. A filler costs about NT $5,000. Euro Arc recommends TORR's Euro Arc series, which can lead to a rich balanced flavor of caramel, nuts and drupes. It is suggested that coffee players should try a lot of different fillers to choose their favorite fillers.
