Where can I get green coffee beans?
It is important that you use green coffee beans in which the silver skin has been removed for roasting with your Röstmeister coffee roaster. We offer a choice of eight different varieties.
What is the Röstmeister warranty period?
In any case, our Röstmeister comes with a two-year-warranty. We also guaranteed the safe delivery of your Röstmeister coffee roaster by post and will replace the unit if delivered in a defective condition.
Which coffee varieties do you recommend?
It is always difficult to make a recommendation as we know that tastes vary. Why don’t you first explore the qualities delivered with your starter set, as a single variety or by putting together your own blend, and then order your favourite coffee as an individual order or by subscription!
How long can coffee be stored?
Green coffee can be stored for a very long time. The storage period of our green coffees is between 1 and 1 ½ years – ideal for storage in your pantry. Therefore, you can easily order larger quantities. What matters for a good coffee taste is that the roasted coffee is used within two weeks of roasting. So, expect to experience unparalleled freshness!
Are there more varieties to come?
Yes... of course! Certainly, we do have to think in business terms, but, looking at our increasing sales numbers, we are planning to expand our range of coffees.
What are the differences of green coffees?Experts agree on the following quality classification:
|Good to very good qualities are made from:
Inferior qualities are made from:
Intense and strong qualities are made from:
|washed Arabica coffee beans
unwashed Arabica coffee beans
Robusta coffee beans
However, even within these groups, there may be very big differences depending on altitude, soil quality and climate.
It goes without saying that, as a "Dieckmann Aroma Kaffee customer" you will only receive top qualities from the best category for your filter coffee.
High-altitude coffees have the best quality. The so-called Arabica only highland coffees are marked by a fine acidity and excellent taste due to their special growing conditions.
What makes Dieckmann Aroma Kaffee unique?We offer "whole beans" only: You can actually see the high quality of the raw product.
We process "washed coffee" only. We do not distribute Robusta, unwashed Arabica or cheap coffees, with the exception of Espresso, which needs some Robusta to get the right creaminess.
All our coffees are pre-treated by the Lendrich process in which the coffee is subjected to hot steam treatment for very intense cleaning. Processing green coffee beans using steam, pressure, temperature and humidity causes a certain modification of the substances in the green coffee beans, in particular of the carbohydrates and proteins, and may result in small colour changes of the beans. To some extent, this may also result in a degradation and alteration of acids. This is why Dieckmann Aroma Kaffee is very mild.
Which type of preparation and grind should I use?
Coffee aficionados apply high standards to their coffee. Following a few rules when preparing coffee will make it easy for you to serve coffee for the connoisseur.
It is particularly important to use a sufficient quantity of coffee. Too little coffee will not provide the enjoyment you expect for yourself and for others. As a rule of thumb, use one level coffee measuring scoop ( 6 to 8 grams) per cup for filter coffee. To maximise flavours, the right type of grind must be used according to the type of preparation. In most cases, fine, medium or coarse grinds are used. Espresso needs a fine grind. A medium-grind coffee is used for coffee makers and hand filters. Coarsely ground coffee is used in large-scale coffee machines.
Coffee connoisseurs use coffee pots made from china, ceramics or glass. These materials guarantee the true taste of the coffee. Coffee lovers want to enjoy their coffee as fresh as possible. Nevertheless, coffee can be kept warm for a short time. The best way is to use a thermos with a glass insert. It is important, however, to not reheat the coffee. In any case, you should avoid letting your coffee stand on a warming plate for a longer period of time, i.e. for more than 15 minutes, because the coffee continues to brew. The water evaporates, the aromas dissipate and the coffee becomes increasingly bitter.
A whole beanAs long as the coffee is intact, i.e. as whole beans, its aroma is still enclosed in the bean. With proper packaging, it can be kept fresh up to 3 weeks or up to 6 or 10 weeks when stored in the fridge, and in a freezer even up to one year without any mayor deterioration of quality. A true coffee connoisseur and aficionado will grind the coffee immediately before preparation. This is the only way to experience the full pleasure and magic of unparalleled coffee aromas.
|Grind level||VERY FINE|
|Level 1||For Turkish Mocha|
|Level 2||For the Espresso maker|
|Level 3 - 6||For filter coffee|
|Level 4||For coffee machines with a cone-shaped
filter for brewing in a pot
|Level 5 - 7||For coffee machines, for decaffeinated coffees|
|Level 6 - 8||For round-filter coffee machines|
|Level 7 - 8||For gold-filter coffee machines|
|Level 6 - 8||For large-scale coffeemakers|
|Level 9 -12||For large-scale coffeemakers only|
Decaffeinated coffees should always be ground coarser by 1-2 levels, i.e. at level 5-6 for coffee makers.
How should I roast and store my coffee?
No need to get up half an hour early every morning to roast your daily quantity.
You’ve got to know that the specific coffee aromas come from a number of primary and secondary chemical reactions during roasting, with more than 800 aromas identified to date, but the taste of roasted coffee often becomes much more intense and aromatic after resting for a few hours.
Just roast the quantity you need for the next couple of days whenever you’ve got the time - in the evening, on the weekend, just by yourself or together with friends – and store the roasted beans in your fridge. Any packaging that prevents oxygen from coming into contact with the coffee is suitable for storage.
While the individual whole bean provides a certain protection of the coffee aromas,
"oxygen is the no. 1 enemy of aromas"
because the aromas evaporate when in contact with oxygen, the aromatic substances in the roasted coffee oxidize and, after a while, the coffee is going stale.
- Roast the green coffee beans according to individual taste
- Immediately store the freshly roasted coffee beans in your fridge
- Remove and grind as needed
- Enjoy the freshest and most aromatic coffee you can possibly get
Roasted coffee even preserves its fresh aromas for up to 12 months when frozen (coffee doesn’t have to be thawed for grinding).
Your green coffee can be kept in a foil bag for up to 18 months when stored in a cool and dry environment.
