How to choose the grinding fineness of hand brewed coffee beans
Hand-poured coffee is a traditional brewing method that emphasizes the effect of the grinding size of coffee beans on the taste and flavor. Choosing the right grinding size can help us make hand-poured coffee with better taste and flavor. This article will explore how to choose the right grinding size for hand-poured coffee beans based on different factors.
1. Raw materials and origin
First of all, we need to consider the impact of raw materials and origin on the hardness and density of coffee beans. Generally speaking, different origins, varieties and processing methods will result in coffee beans of different hardness and density. Softer and low-density coffee beans (such as those produced in Asia) usually require finer and more uniform grinding; while relatively hard and high-density varieties (such as those produced in South America or Africa) usually require slightly rougher crushing.
2. Brewing equipment
Secondly, we need to consider the requirements of the brewing equipment for the grinding coarseness. Different hand-brew equipment has different filtering methods and speeds, so you need to choose a grinding coarseness that suits the equipment. For example, a French press usually requires a rougher crushing to prevent too fast penetration and cause the coffee to taste astringent; while a slow drip coffee machine requires a more delicate and even crushing to ensure that the coffee aroma is fully extracted.
3. Brewing time
In addition, we also need to consider the effect of the desired brewing time on the grinding coarseness. Generally speaking, a finer and more uniform crushing can increase the contact area between water and coffee and improve the extraction efficiency; while a relatively coarse grind will prolong the extraction time but also bring a richer, fuller and richer taste.
4. Taste and flavor preferences
Finally, we also need to choose the grinding coarseness according to personal taste and flavor preference. If you like a light and light taste, you can choose a finer crushing; if you like a rich and full taste, you can choose a slightly coarser crushing.
In short, the choice of grinding fineness of hand-brewed coffee beans needs to consider factors such as raw materials and origin, brewing equipment, brewing time, and personal taste and flavor preferences. Only by adjusting according to different situations can you make hand-brewed coffee that suits your taste.
