About Cores and the feeling in the cup
Cores is a Japanese brand focused on brewing equipment that lets the coffee’s own aromas and character come through clearly. Their gold filters use a gold-coated metal mesh, chosen to affect flavour and aroma as little as possible while resisting odours and build-up better over time. The idea is simple: less between the coffee and the cup, more of the bean’s natural expression.
This range is for you if you want to brew without paper filters and retain more of the coffee’s oils and body in the result. Compared with paper, the experience is often rounder and more direct, while brewing is quick and everyday use is simpler: no filter paper to restock, less waste, and easy cleaning afterwards. Choose the model that fits your brewer and the amount of coffee you usually brew at home.

A reusable solution for everyday brewing at home.
Gold filter for everyday brewing
Ideal for those who want clear flavour, fast flow-through, and easy maintenance without disposable filters.
More of the coffee’s own body
The metal filter lets through oils that paper filters normally trap, resulting in a fuller, more aromatic cup.
How it works in practice
brew with medium to medium-coarse grind, let the coffee bloom briefly, and rinse the filter clean immediately after use for easy everyday care.
For brewers with a Melitta fit
This option is for you if you want to replace paper filters in a familiar brewing format and get a more open, oil-rich result in the cup.
Easy to live with every day
After brewing, it is normally enough to rinse the filter with water. Less consumption, less waste, and less to think about between brews.
Frequently asked questions
Answers to the most important questions before you choose.
How does the taste differ from paper filters?
The biggest difference is that more of the coffee’s oils make it into the cup. This usually gives more body, clearer aroma, and a less filtered feel than brewing with paper.
Is it normal for there to be a little sediment in the cup?
Yes. Since it is a metal filter, a small amount of fine particles may pass through during brewing. This does not affect the quality, but if you are sensitive to it, you can leave the last small splash in the cup.
Do I also need to buy paper filters?
No. This type of filter is used without a paper insert, making brewing both easier and more economical over time.
How do I clean the filter?
Rinse it immediately after use and it is usually ready. The gold coating is chosen to resist chemical changes and be less prone to absorbing odours, making the filter easy to keep fresh.
