the main component of the finished Cold Drip Coffee.

For pure indulgence, it’s best to use cold, filtered water. You can add ice cubes so the water remains cold during the entire brewing process. A full tank holds approximately 600ml.


The most important ingrediant.

The taste of the finished cold drip coffee highly depends upon the quality, freshness and roasting of the coffee beans. We recommend using relatively freshly grounded coffee, the beans should be brightly roasted and coarsely grounded. Per 100 ml of water use 7-10 g of coffee (the filter holds approximately 45 g). Do not press together the powder in the filter too strongly as the water will then not be able to flow through.

If you use little coffee or a very coarse grinding, you can use a filter on the coffee to spread the water more evenly. Or you drip water once over the entire powder surface.

Drip Speed

Correct setting of the DRIPSTER.

We recommend a setting between 0.5 and 2 drops per second. The brewing process will then take about 1 to 2 hours. Through a slower extraction from the cold drip the coffee becomes more intense. Note that the speed decreases due to the falling water pressure over time. If you start with a setting that is too slow, you need to readjust the valve during the brewing process.


the “unpopular” part.

Most of the parts are made of clear plastic. You should rinse them by hand as regular dishwasher cleaning may make the plastic cloudy. The coffee container made of PYREX glass can be placed and cleaned in the dishwasher.

All parts of the DRIPSTER should be rinsed once before the first use.


How to drink the Cold Drip Coffee.

You should stir the finished cold drip coffee once as many flavors are extracted at the beginning and decreases over time.

You can drink the Cold Drip Coffee pure on ice or diluted with water or milk. The Cold Drip Coffee is also very suitable as a cocktail ingredient – it harmonizes particularly well with tonic water (alcohol-free ColdDrip Tonic) and orange juice.


and storage.

The finished Cold Drip Coffee is best kept in a sealed container in the refrigerator. Hereby, it stays fresh for about three days.

Frequently asked questions and problems

First, you might have set a too slow drip speed. As a result of the decreasing water pressure the dripping speed also decreases, due to physical factors. In this case, you can set a higher drip speed on the valve.

If this does not help, you should check whether air can flow through the hole in the lid of the water tank. If this hole is closed, a vacuum can form, which prevents water from flowing through the valve.

The DRIPSTER works according to the Cold Drip method, which we consider as the superior method (See here for a comparison of the methods). When comparing different manufacturers the functionality of the DRIPSTER is especially well thought out (details can be found here) and the DRIPSTER is very compact and at the same time modernly and elegantly designed. In addition, the DRIPSTER is particularly inexpensive and therefore affordable to all households.

Normally, the entire coffee powder is evenly extracted even though the water always drips onto the same point. The coffee dreg should be entirely moist after the end of the brewing process. The coffee powder absorbs the water evenly and does not release the absorbed water until enough water has dripped in.

Sometimes it can happen that the drops pass very quickly through the coffee powder and the coffee does not become evenly moist. This results in a rather weak cold brew. This problem mainly occurs when the coffee is less absorbent and therefore prevents the water from spreading evenly through the entire powder. Low absorbency is a results off the coffee or grinding being slightly old, the coffee being very coarsely grounded, or lastly if you do not use enough coffee powder.

In this case, you have two options: Before you set the valve, you can drip water onto the entire surface of the coffee powder once. If the entire surface is moist, the drops are being distributed evenly. Alternatively, you can put a paper filter on the coffee powder so that each water drop is spread more evenly. Hereby, coffee or tea filters cut down to the right size are suitable.
