What is a geyser coffee maker and how it works
A geyser coffee maker is a compact device that can brew coffee with high quality. It works on the principle of repeatedly boiling water and raising its steam under pressure. The first such device appeared in Italy in 1933. Since then, geyser coffee makers have gained popularity around the world due to their ease of use, reliability, and ability to prepare a rich, flavorful coffee drink without the need for electricity.
The device consists of three main parts: a lower water tank, a metal funnel-shaped filter for the ground beans, and an upper tank for the finished beverage. The lower part also has a safety valve that prevents excessive pressure. Coffee makers are mostly made of aluminum or stainless steel. Some models have ergonomic handles, an induction bottom, and even a glass top flask for visual control of the process.
The principle of operation is quite simple. The water in the lower part heats up, turns into steam, and creates pressure that pushes the hot water through the grinds in the filter. This liquid then rises up through the central tube into the upper reservoir, where the finished drink is stored. The whole procedure takes about 5-10 minutes, depending on the volume of the coffee maker and the intensity of the heating.
Coffee makers are identified by the number of cups they can brew at a time. For example, a 3-cup model means that you will receive approximately 150 ml of drink (approximately 50 ml per serving). 6 cups is about 300 ml, and 9 cups is almost half a liter. We are talking about espresso portions, not large cups.
How to choose a geyser coffee maker
There are several important factors to consider when choosing a geyser coffee maker. First of all, the material. Aluminum models are lighter and cheaper, but less durable. Stainless steel is resistant to corrosion, better preserves the taste and aroma of the beans, and is also suitable for induction cookers.
The second point is the volume of the coffee maker. Manufacturers usually indicate the number of espresso cups (50 ml each) that can be brewed at a time. If you drink coffee alone, a 1-3-cup model is enough. For a family or guests, it’s better to get one for 6 or 9.
Also pay attention to the compatibility with the type of stove, the presence of an ergonomic handle and a safety valve.
The geyser coffee maker makes a rich, aromatic drink with a deep espresso-like flavor. It is easy to use, does not require electricity, and is travel-friendly.
Brewing coffee in a geyser coffee maker is a great option for those who like the traditional method.
Preparing to make coffee in the geyser coffee maker
To brew coffee in a geyser coffee maker to a high standard, it is important to prepare for the process properly. Preparation includes selecting high-quality ingredients, the right accessories, and maintaining the optimal proportions of ground beans and water.
The main thing is fresh ground coffee, clean drinking water, and the device itself. Additionally, you may need a measuring spoon, thermal dishes for serving the drink, and a napkin or towel to clean the coffee maker after use. If you grind your own beans, you will also need a coffee grinder.
For a geyser coffee maker, it is best to choose medium or dark roasted beans. It is this kind of coffee that gives a rich flavor and distinct aroma. You can use both 100% Arabica and blends with Robusta, which adds strength and creamy texture.
It is important to choose quality coffee from trusted manufacturers. Kyiv City Roastery invites you to familiarize yourself with a wide selection of freshly roasted beans for making coffee in a geyser coffee maker. In addition, we always offer the best price and have a long-standing reputation.
The ideal grind for a geyser coffee maker is medium, similar to fine sand. Grinding too fine can result in excessive bitterness, while grinding too coarse can result in a watery, unsaturated drink. If you grind the beans just before brewing, select the appropriate grinding setting.
The amount of ground beans depends on the size of the coffee maker. For example, a 3-cup model requires about 15-18 grams.
Step-by-step instructions for making coffee in a geyser coffee maker
- Pour water into the lower reservoir up to the control valve – no higher to avoid excessive pressure.
Use hot water (not boiling water) to reduce the heating time. - Pour the grinds into the funnel-shaped filter to the very edge. Make sure that the coffee does not spill over and onto the rim of the filter, as this may compromise the seal. There is no need to tamp it down! This is not an espresso machine. The coffee should lie loose. If it is compacted, the water will not be able to pass through the grinder properly, and this will impair the taste or even damage the coffee maker.
- Carefully screw the upper part of the coffee machine to the lower part. Make sure that the connection is tight and even – no misalignment.
- Place the coffee maker on the stove. Turn on medium or low heat. High temperatures can lead to overcooked beans. If you are using an electric stove, select medium power.
- It takes about 4-7 minutes to brew coffee in a geyser coffee maker, depending on the volume of the coffee maker and the heat setting. Follow the sound and visual signals – the drink will begin to pour out to the top with a characteristic “hiss”.
- When the flow is even and the sound changes to a gurgling sound, the coffee is almost ready. Remove the coffee maker from the heat as soon as the upper reservoir is full. Do not leave it on the fire to avoid overcooking the drink.
Secrets of making the most delicious coffee
Brewing coffee in a geyser coffee maker seems simple, but a few little tricks can make the taste of the drink even deeper, softer, and more flavorful.
We have already mentioned using hot water rather than cold water. It reduces the heating time and prevents the grind from being “burned” while waiting.
It is important to clean the coffee machine after each use without detergents. Just rinse well with water. Soap residue can spoil the taste.
Store the ground beans in an airtight container and do not keep them near spices or other aromatic foods. They absorb odors quickly.
Do not tamp the grind in the filter – allow the water to pass freely through the ground grain.
Remove the coffee maker from the heat when you hear a hissing or bubbling sound. Overcooked coffee tastes bitter.
Use soft or filtered water for a more pleasant taste.
A geyser coffee maker is not only a coffee classic, but also a space for culinary experiments.
With this device, you can make coffee that will be special just for you
The most common variant is the Italian classic: ground beans of medium roast without additional ingredients. This coffee has a rich flavor and aroma and is served in a small cup, with or without sugar.
For lovers of soft drinks, coffee with milk or, as it is also called, “geyser latte” is ideal. Mix the prepared drink with hot milk in a 1:1 ratio. If you wish, you can add a pinch of cinnamon or a drop of vanilla extract to make the drink delicate and flavorful.
Chocolate lovers should try the chocolate mocha.
Before brewing coffee in a geyser coffee maker, pour ground beans, 1 teaspoon of cocoa powder, and a little sugar into the filter. After brewing, add a little warm milk or cream – you will definitely enjoy the result
Another interesting option is spiced coffee. Add a pinch of cinnamon, nutmeg, or ground cardamom to ground coffee. This drink has a deep flavor and a pleasant warming aroma – perfect for cool mornings.
Maintenance and care of the geyser coffee maker
To ensure a long service life, wash the device after each use with warm water and no detergent. Be especially careful to clean the filter and O-ring. After washing, be sure to dry all parts to prevent corrosion or odors. Store the coffee machine in a dry place when it is disassembled. Regularly check the condition of the gasket and valve – it is important to replace worn parts in time.
Solving common problems
- The coffee maker is leaking.
This is most commonly caused by a worn sealing gasket or loose parts. Check the rubber ring, filter, and threads. Replace the gasket if necessary.
2. Water does not rise. There are a number of possible reasons for this:
- The filter is clogged
- The tube is blocked
- Grinding is too fine
- The grinding is too tight
- Water exceeds the valve level.
By the way, don’t forget to check the valve for contamination.
3. Coffee is liquid or has sediment
The reason may be that the grind is too coarse or not enough. It is also important to spread the grind evenly in the coffee maker without leaving any voids. This can also happen if the beans are old or too wet.
4. The coffee is bitter.
This is most often the result of overheating. Use hot water to start the process and remove the coffee maker from the heat as soon as bubbling occurs. Also check the quality of the beans and the degree of roast.
5. Water remains in the lower reservoir
This may indicate low pressure – check that the safety valve and center tube are not dirty. Also make sure that the coffee maker is properly assembled and that the fire is not too weak.
Additional features of the geyser coffee maker
The geyser coffee maker is designed specifically for brewing coffee, but some experimenters use it for other drinks as well
Technically, you can also make tea in a geyser coffee maker, but this is not the best option. High temperature and pressure are not suitable for delicate leaves – the taste is too tart.
Making cocoa in a geyser coffee maker is also not a good idea. The cocoa powder or chocolate chips can clog the filter and the tube, which is dangerous for the user and can lead to breakage.
So, although the geyser coffee maker can be used in a variety of ways, it is still at its best when brewing coffee.
