Why are GBW (Grind by Weight) Espresso Grinders More Accurate Than Timed Grinders?

GBW (Grind by Weight) espresso grinders are considered more accurate than timed grinders for several reasons:

Consistent dosing 

GBW grinders use built-in scales to measure the actual weight of the coffee grounds being dispensed. This ensures that the desired dose is achieved consistently, regardless of variations in grind size, bean type, or bean density. Timed grinders, on the other hand, rely on a set time to dispense coffee grounds, which can result in inconsistent dosing due to the factors mentioned above.

Less influence from external factors 

GBW grinders are less affected by external factors such as humidity, temperature, or bean age, which can impact the flow rate of coffee grounds through the grinder. Timed grinders are more susceptible to these changes, which can lead to inconsistency in the amount of coffee dispensed.


GBW grinders allow for precise adjustments to the desired coffee dose, usually in increments as small as 0.1 grams. This level of control enables you to fine-tune your espresso recipe for optimal extraction and flavor. Timed grinders typically offer less precise control over the coffee dose.

Improved extraction

Accurate dosing provided by GBW grinders contributes to optimal coffee extraction, resulting in a well-balanced and better-tasting espresso. Inconsistent dosing from timed grinders can lead to under-extracted or over-extracted coffee, negatively affecting the taste and quality of the espresso.

Reduced waste

GBW grinders dispense the exact amount of coffee needed for each shot, minimizing coffee waste and saving money in the long run. Timed grinders, with their less precise dosing, can lead to wasted coffee due to over- or under-dosing.

In summary, GBW espresso grinders are more accurate than timed grinders because they provide consistent dosing, are less influenced by external factors, offer greater customization, improve extraction, and reduce waste. These advantages make GBW grinders an attractive choice for those seeking precision and consistency in their espresso preparation.
