It should be fun and easy to repeat to make reliably delicious espresso coffee at home. Do you know what could be changed to make your taste of coffee even better?
1. The correct ratio of coffee to water
This ratio is the main factor in determining the strength of the brew. If you want to take your home espresso to the next level, then dosing in and out is of utmost importance. For dosing properly, you only need to get yourself a scale to weigh the coffee grinds going into your portafilter or dosing cup. We would recommend a ratio of 20g ground coffee in and 40g coffee out in 27 seconds.
2. Matching the coffee grind size to your type of brewing equipment
Extraction rate, contact time, and flow rate are three main elements impact your cup of coffee taste.
- The extraction rate of coffee grounds increases with more surface area.
- Increase surface area by grinding coffee finer.
- With a higher extraction rate, less contact time is required.
- Finer grind reduces the flow rate of water, which increases contact time
Coarse Grind is best for Cold Brewing, French Press, Chemex.
Medium Grind is best for automatic drip brewer, pour over and syphon.
Fine Grind is also called espresso grind, which is best for espresso
Extra-Fine Grind is the grind size when you are brewing Turkish or Greek Coffee.
We recommend you get a burr grinder because it will give you consistent grind size, thus vastly improving your brewing and tasting experiences.
3. Freshness of Coffee Bean
Purchase coffee bean after it is roasted as soon as possible. Fresh roasted coffee is key to a quality cup of coffee, therefore, purchase your coffee in small quantities and avoid purchase pre-grounded coffee in order to keep the flavor and taste of coffee as much as possible.
4. Quality of Water
Since an ideal drip coffee drink is actually more than 98% of liquid, hence, making water is as clean as possible is important. For clean taste and proper brewer activity, a filter that removes chlorine and inhibits scale build-up is usually necessary in proper brewer operation.
5. Brewing Time
The amount of time that the water is in contact with the coffee grounds is another important flavor factor.
In a drip system, the contact time should be approximately 5 minutes. If you are making your coffee using a French Press, the contact time should be 2-4 minutes. Espresso has an especially brief brew time — the coffee is in contact with the water for only 20-30 seconds. Cold brew, on the other hand, should steep overnight (about 12 hours).
If you’re not happy with the taste of the final product, you’re likely either:
- Over-extracting – the brew time is too long
- Under-extracting – the brew time is too short
Experiment with the contact time until you get the right balance for your taste.
Luckily, modern technology offers us a more in-depth view of a coffee beverage’s basic make-up. By carefully analyzing the finished beverage using, we can adjust each individual parameters of the coffee recipe to maintain consistency and quality in every coffee you prepare and serve.
