*Household use only.

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

Cores Gold Filter is designed for making aromatic coffee with good flavor.

This gold filter is strongly recommended by Maruyama coffee.

Material

The gold filter is made with the gold plated stainless and gold does not cause a chemical reaction, so coffee come through the filter is not oxidized.

Round mesh filter	Longitudinal slot of Cores Filters

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

Shape

Its unique longitudinal slot helps water flow out faster without lowering the water temperature much. And all the slits are punched from inside toward outside so water flow is also much smoother. As a result, tasty coffee with good flavor and without miscellaneous taste is prepared. And more, the mesh hole is even so will not be deformed.

All the slots are punched from inside to outside in order to let water flow smoother.

Punching

All the slots are punched from inside to outside direction, so water flow from inside to outside is also smoother.

*Please use the cores cone filter in a cone-shaped filter holder.

*The filter mesh is designed for extracting all good ingredients from the coffee and so some fine coffee particles can pass through the mesh. This will not affect the coffee quality and taste.

Good solution to optimise extraction

Lower area of filter is flat

Raised base

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.

Other cone shaped filters

Round mesh filter	water

If coffee particles become trapped in the round mesh then the hole can become clogged. As a result, water does not flow smoothly.	Water flow tends to gather at the base of the filter, so the coffee liquid tends to be over extracted in the lower area of the filter.

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.

Cores Cone Filter

Longitudinal slot of Cores Filters	water

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.

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 short time brewing with very high temperature.

The drip tray can be used as a lid for the filter

The cone filter can be put on the drip tray. The tray can also be used as a lid for the filter.

HOW TO USE

Boil the water.

Place the filter on a cone-shaped dripper.

Put ground coffee in the filter and level out before pouring.Max capacity of ground coffee is 64g.

The first pouring is just for blooming.Pour water inside the center circle of the coffee and bloom the coffee for 40 seconds.
The volume of water for the 1st pouring shall be equivalent to the weight of the ground coffee.

After blooming,continue to pour hot water divided into several times.Hot water shall be poured to be evenly spread all over the ground coffee.

After pouring the required volume of hot water, remove the filter from the filter holder.Stir the coffee liquid with a spoon to even its strength.

*1pc drip tray is included in the product.This drip tray can also be used as the lid for filter.

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.
