General tips and tricks for brewing


We love sharing our brewing knowledge to help you make excellent coffee at home, because there are many moments when things can go wrong - from the roasting machine to the cup. So continue reading to become a coffee brewing expert!

General preparation of your equipment
We highly recommend weighing your coffee and the amount of water you use for brewing. This way you will always get the best results. Therefore, we recommend using a scale to weigh out the exact amount of coffee and water you need for your brew.


The following facts are relevant for you:
1ml of water = 1g of water
Basic equipment for coffee preparation should include:
- Scale
- Hot water
- Nice to have, but not necessary: Grinder

A coffee grinder will help you make your coffee even more delicious by giving it that extra freshness: you can adjust the grind setting if you're not happy with your coffee.

Why should I NOT use spoons with coffee grounds to brew my coffee?
Clearly you can, but let's face it, how much do you really enjoy your daily coffee? ;) That's how people usually do it, one spoon for 1 cup. BUT measuring your coffee grounds by eye is not precise enough to guarantee you a delicious coffee every day. For a great cup of coffee, you can't just buy quality coffee beans and expect excellent results; there also needs to be some investment in your brewing equipment to make the coffee flavorful, complex, and enjoyable.

What difference does the grind make?
Adjusting the grind allows you to customize your coffee.
- If your coffee tastes too acidic, a finer grind is recommended.

- If your coffee tastes too bitter, a coarser grind is recommended.

Since every grinder always works differently, we can only give you rounded numbers to give you a direction to start with.
In addition, every coffee is different; therefore, the grind setting must be adjusted accordingly.
Here are some recommendations for the most popular grinders:
The Comandante is one of the most popular grinders, handmade in Germany. It is effortless to use and provides a consistently good grinding result for your brew. To adjust the grind, adjust the clicks below. The following number of clicks is recommended:
- 8 clicks: Ibrik
- 8 - 15 clicks: espresso
- 15 - 20 clicks: moka pot (Bialetti)


Can I use tap water / What kind of water should I use?
Yes you can, but it's not ideal. All tap water contains many minerals and organics that don't taste great in your coffee. Your water should have a mineral content between 100 and 200 mg/L.
Never use distilled water!
Extraction is a chemical reaction; therefore, you need some minerals in your water to extract the flavors from the water. To find out what the mineral content is in your water, for example, you can check www.mineralienrechner.de/" target=.

A water with a high mineral content to go with your brew is Volvic. 


How do I clean my coffee maker?
Cleaning your coffee maker is essential! To keep the quality of your cup consistently good, cleaning your coffee maker is key. You don't want to taste old coffee, you want to taste your freshly brewed coffee. That's why you want to avoid contamination - from old (moldy) coffee grounds in your machine. So make sure to keep it clean.
First of all, it's important to know that you shouldn't put soap in your coffee maker! How you clean your machine depends on the machine you use - make sure it's as clean as possible. We don't recommend soap, but rinse it with hot water after use. For deep cleaning, it's best to follow the manufacturer's instructions.

Storing freshness: what's the best way to store coffee?
You should keep your coffee in its original packaging. We chose our bags with a valve to allow the freshly roasted coffee to degas, but retain its full flavor potential. Moving the coffee to another storage option is no guarantee that the coffee won't take on the odor of what was previously in the storage unit.
And very importantly, you don't have to store your coffee in the refrigerator - room temperature is perfectly fine.

What actually is a strong coffee?
There are two ways to define "strong": strong in flavor or high in caffeine.
Both types are very different. Strong does not necessarily mean that the coffee is high in caffeine. The Italian idea of a ristretto will have less caffeine than a typical cup of filter coffee. 


What roast style do we use at 19grams?
We like a medium roast - not too light, not too dark, right in the perfect middle: More developed, but still light. 
What is a Nordic roast?
The Nordic countries prefer lighter roasts, because they drink much longer filter coffee methods.
We at 19grams are closer to the Australian ways of roasting coffee. We always use excellent quality and roast them to perfection.
If you prefer a darker roast, reach for the espressos - we also like to brew them as filters!
