リード文

Mesh dimension is even and not easy to be deformed because the material is metal, and no chemical change occurs as a result. From the above reasons, it is little affected to the taste and flavors of coffee. And more, thanks to its unique longitudinal slot, the filter can provide a short brewing time at a very high temperature.

Good solution to optimise extraction

In a normal cone shaped filter, water flow tends to be gathered at the base of the filter. In order to prevent over extraction , the base of our cores cone filter is raised so the water flows outwards, and does not gather in the central lower area. Thanks to this raised base, strong bitterness does not come into the coffee liquid.

*Patent pending

  • Lower area of filter is flat



Cone shape filter from other manufacturers

A filter with small round mesh holes can easily be clogged by coffee particles. So water cannot flow outwards, and flows inside the filter and gathers in the central lower area. Because of this, the coffee tends to be over extracted. The over extracted coffee tastes tends to be with harshness and bitterness.

If coffee particles become trapped in the round mesh then the hole can become clogged. As a result, water does not flow smoothly.

The raised bottom allows the hot water to flow through the side of the filter.

Cores Gold Filter

Because the lower area of filter is flat, so the water can flow outwards and not gather at the central lower area of the filter. That is to say, water can contact with the ground coffee particles uniformly. And more, thanks to the longitudinal slots, the Cores Cone Filter can provide a short brewing time at a very high temperature.

Thanks to the longitudinal slot, even if a coffee particle is in the slot, the hole is not clogged. As a result, water flows smoothly.

The raised bottom allows the hot water to flow through the side of the filter.

HOW TO

How to brew a cup of coffee using a Cores Cone Filter

Boil the water.

Pour hot water right after boiling; never let it cool down.

Set the filter to a dripper which fits cone shaped filters.
Put the ground coffee into the filter.

Required amount of coffee = 8g/cup

Wiggle the filter to flatten the ground coffee.

Pour hot water in a circular motion, starting from the center, in order to get the entire coffee wet.

Required amount of hot water for the first pour = the amount of coffee used. (e.g. Pour 8ml of hot water for 8g of coffee used)

Wait around 40 seconds for infusion.

Keep pouring hot water, little by little, making sure the entire coffee gets wet.
Once finished pouring hot water, remove the filter quickly.

Stir the coffee in the cup well to level the strength.

*Due to the nature of metal filters, there will be a small amount of ground coffee in the cup, however, this does not affect the quality of the cup. You may choose not to drink entirely and leave the coffee grounds on the bottom of the cup.

*We recommend using freshly roasted coffee, in order to hold hot water long enough.

丸山珈琲からのコメント

Recommendation by Maruyama Coffee

Thanks to the raised base, water flows out from the side walls of the filter. So, strong bitterness does not come into the coffee liquid. If you put fresh specialty coffee in the Cores Cone Filter, you can enjoy a pleasant aftertaste with high-quality sweetness and acidity.
