The material of the dripper is a very important factor in brewing coffee.
The key is to reduce heat loss as much as possible, which is why plastic drippers are used the most.
However, just because a plastic dripper is not without its drawbacks.
Polycarbonate plastic material can absorb flavor compounds, which can have a slight effect on coffee flavor.
In addition, the plastic material of HDPE (High Density Polyethylene) can cause micro cracks, which can affect the taste of coffee.
Conversely, glass drippers have a smooth surface.
However, glass has a fatal disadvantage that it is fragile and does not retain heat well during coffee extraction.
The order of greatest heat loss is ceramic > plastic > double wall glass.
In conclusion, plastic is the best option for reducing heat loss, depending on the coffee you are brewing.
You must have an eye to choose plastic, glass, and ceramics.
