Multi-Serve Pour-Over Coffee: A Tutorial on Adjusting Brewing Parameters for Large Batch Quantities - 4-Serve Pour-Over Coffee Brewing Guide

Recently, some friends have asked FrontStreet Coffee, "How should I brew coffee for multiple servings?" FrontStreet Coffee previously touched upon this when discussing coffee dosage in pour-over parameters. This time, FrontStreet Coffee will elaborate on how to brew coffee with large doses.

An increase in coffee dosage means that closely related parameters will also change – the amount of water will increase proportionally, and the pouring time will extend accordingly. However, there's one factor that affects the upper limit of coffee dosage for brewing: the filter cup.

Given that most people have purchased the #01 filter cup (small size) designed for 1-2 servings, normal brewing should not exceed 20g of coffee. If you want to brew coffee with larger doses, the simplest and most direct method is to purchase a #02 filter cup and #02 filter paper (yes, the filter cup and filter paper must match). This larger filter cup can easily brew 40 grams of coffee grounds.

In fact, brewing with large doses offers greater tolerance and higher error forgiveness in pouring techniques. For example, when brewing with small doses (15g), undesirable flavors often result from uneven water flow, inconsistent circular pouring, or channeling through the coffee bed. With increased dosage, these impacts become less significant.

Brewing with a #02 Filter Cup

If you're using a #02 filter cup for brewing, you simply need to convert the parameters proportionally. FrontStreet Coffee will demonstrate this using a #02 filter cup to brew 30g of coffee grounds.

When pouring water, you can follow the three-stage pouring principle, but with a larger water flow to elevate the coffee bed and replicate the brewing model of a #01 filter cup.

Brewing Large Doses with a #01 Filter Cup

If you don't have a #02 filter cup but want to brew coffee with large doses, the following situation will likely occur:

The filter cup cannot contain the coffee grounds and water, nearly overflowing. Does this mean small filter cups cannot brew large doses of coffee? Not necessarily – it's possible with appropriate parameter adjustments.

Due to the cup's limitations, we cannot inject too much water at once, or it will overflow. Therefore, FrontStreet Coffee recommends adopting a multi-stage, small-volume pouring approach. Additionally, we don't want the water to soak in the coffee bed for too long, which would produce bitter flavors.

Consequently, the grind size should be coarser than normal, approximately 70% retention on a #20 sieve. This allows the coffee brewing process to achieve true "wash-drip extraction." The water temperature remains unchanged.

Demonstration: Brewing 30g with V60 #01

FrontStreet Coffee demonstrates brewing with 30g of coffee grounds using a V60 #01 filter cup. First, pour 50ml of water for a 35-second bloom. Due to the increased dosage, the coffee bed is thicker, so extending the bloom time is necessary to allow the coffee grounds to release gas completely.

For the second stage, pour 100ml of water in small circular motions in the center. Control the water flow according to the expansion of the coffee bed to avoid overflow.

After the water level drops, pour 100ml of water in larger circles than the second stage, again preventing overflow.

After the water level drops again, pour another 100ml of water in even larger circles than the third stage.

For the final 100ml of water, pour vertically in the center. The total water amount is 450ml, with a brewing time of approximately 3 minutes.
