Determining the grind size for pour-over coffee is an art that directly influences the flavor, extraction time, and overall drinking experience. Here are some professional tips to help specialty coffee enthusiasts brew the perfect cup.


Understand Different Coffee Beans

The first step in choosing the grind size is to consider the type of coffee beans. Different origins, processing methods, and roast levels result in varying physical properties and flavor profiles. For instance, light roast coffee beans are usually harder and require a finer grind to fully extract their flavors, whereas dark roast beans are more brittle and can be ground a bit coarser.


Adjust Grind Size to Suit Different Brewing Methods

Different coffee brewing methods, such as French press, Chemex, pour-over drippers, espresso machines, or Moka pots, have different requirements for water flow rate and contact time, necessitating different grind sizes. For example, a pour-over dripper requires a medium-fine grind (similar to table salt) to extend the contact time with water, thereby fully extracting the coffee's flavors. In contrast, a French press or cold brew needs a coarser grind (like coarse sugar) to avoid over-extraction and maintain the coffee's freshness and brightness.


Use Professional Equipment

A high-quality coffee grinder is essential. Manual grinders offer fine control and portability, while electric grinders provide better consistency and convenience. Choosing a grinder that allows precise grind size adjustments can help you easily find the ideal grind setting.


Adjust Grind Size Based on Water Quality and Temperature

Water quality and temperature are also crucial factors in determining grind size. Hard water, which contains more minerals, accelerates the extraction process and therefore requires a slightly coarser grind to balance the extraction time. Conversely, soft water extracts more slowly and needs a finer grind to achieve optimal extraction. The same goes for water temperature—higher temperatures speed up extraction and need a coarser grind, while lower temperatures slow down extraction and require a finer grind to compensate for the longer extraction time.


Experiment and Adjust

No matter how carefully you plan, experimentation is necessary to find the final grind size. This requires multiple trials, recording results each time, and adjusting based on taste and flavor. For instance, if your coffee tastes too bitter, it is usually a sign of over-extraction, and you should use a coarser grind. If the coffee tastes too sour, it may be under-extracted, requiring a finer grind.



Determining the grind size for pour-over coffee is not static; it requires adjustments based on the characteristics of the coffee beans, brewing method, water quality, and temperature. It's recommended to experiment and adjust during the brewing process to find the grind size that best suits your taste. This not only enhances the quality of your coffee but also deepens your understanding of the charm of coffee.

Summer is getting hotter, and nothing beats a glass of ice-cold coffee to cool you down. Ice coffee is a collective term, and it can be prepared in different ways. Today, we'll introduce three commonly used methods:


1. Cold Brew

Cold brew involves steeping coffee grounds in cold water or slowly dripping cold water onto the grounds. This method produces a smooth, low-acidity coffee, but it takes 4-8 hours to brew. Some people find that certain aromas may not be fully extracted, resulting in a less vibrant taste. However, cold brew coffee is known for its longer shelf life. At home, you can choose high-quality beans and proper equipment to enhance the final product.

 · Grind Size: Medium-coarse

 · Brew Ratio: 1:10~1:13

 · Amount of Coffee: 30-50g

 · Brewing Time: 4-8 hours

*We recommend using medium-roasted, washed, or the natural honey method beans to avoid excessive fermentation flavors (personal preference should ultimately guide your choice).


2. Cold Drip

Using a dedicated cold drip coffee apparatus, such as the Timemore Ice Dripper, drip the appropriate amount of chilled water onto the coffee grounds.This slow process takes time(typically 2.5-4 hours),resulting in a smooth, delicate taste without overly acidic or sharp flavors.

· Grind Size: Medium-fine

· Brew Ratio: 1:10

· Amount of Coffee: 30g

· Brewing Time: 2.5-4hrs


3. Flash Chill

Also known as Japanese-style iced coffee, this method involves rapidly cooling hot-brewed coffee to lock in its delicate flavors. Brewed coffee is dripped directly onto ice, rapidly cooling it and diluting it to the desired strength. This method takes only a few minutes and is my personal favorite, but the coffee should be consumed the same day.

 · Grind Size: Medium-coarse

 · Brew Ratio: 1:15

 · Amount of Coffee: 20g

 · Brewing Time: 2-3 minutes


Whether you prefer the rich taste of cold brew, the distinct layers of cold drip coffee, or the refreshing complexity of flash-chilled coffee, these methods will bring you a refreshing and enjoyable experience. In the hot summer, a glass of chilled coffee will be your best companion.


Let's enjoy the wonderful season that iced coffee brings together!

1. Choosing the Right Coffee Beans

When it comes to brewing the perfect cup of coffee at home, the first step is to select the right coffee beans. Because coffee beans that have been left for too long may no longer retain their fresh flavor, it is recommended not to grind the coffee beans in advance. Instead, grind them just before use. If using a filter brewing method, it is also important to pay attention to the expiration date. Storing coffee beans in an airtight container in a cool, dark place helps maintain their freshness and flavor.


2. Essential Coffee Brewing Equipment

To brew delicious and rich coffee, besides having fresh and suitable coffee beans, having appropriate coffee brewing equipment is essential. Firstly, a coffee grinder is necessary, whether it's an electric or manual grinder, to keep the beans fresh and grind them into suitable particles, which is the key to brewing high-quality coffee. Secondly, a digital scale that can accurately measure weight (ideally with a built-in timer) is needed. Next, a gooseneck kettle, which can precisely control water flow, is essential. With these tools in place, you can start brewing coffee.


3. Brewing Techniques and Ratios

Mastering the art of brewing coffee involves understanding the brewing techniques and ratios. A step-by-step guide to brewing coffee includes grinding the beans to the appropriate size, selecting the brewing method, and controlling the water temperature and quality. The importance of water temperature and quality cannot be overstated, as it directly impacts the extraction of flavors from the coffee grounds. Understanding the coffee-to-water ratios is essential for achieving the desired strength and flavor profile in the brewed coffee.


4. Enhancing the Coffee Experience

To elevate the coffee experience at home, exploring different brewing methods, such as cold brew, can introduce new flavors and aromas to the cup. Additionally, adding flavors and spices to coffee, such as cinnamon or vanilla, can create unique and personalized coffee blends. When serving and enjoying coffee, using high-quality, freshly ground beans and the right brewing equipment ensures a delightful and satisfying coffee experience.


In conclusion, brewing a delicious

cup of coffee at home involves a combination of selecting the right coffee beans, utilizing essential brewing equipment, mastering brewing techniques and ratios, and enhancing the overall coffee experience. By paying attention to these key aspects, coffee enthusiasts can indulge in the art of home brewing and savor the rich flavors and aromas of a perfectly brewed cup of coffee.


Each brewing is a care and concern for oneself, a pursuit of the beauty of life!
