Introduction:When you want to brew 2–3 cups of coffee in one go with a pour over, but find your small V60 filter cone can’t handle the volume, the V60 Size 02 large filter cone is the ideal choice. This article uses 30 grams of coffee grounds in a real-world test to explore adjustments in coffee-to-water ratio, grind size, and pouring technique—solving the issue of over-extraction bitterness, and sharing practical parameters along with multiple bean recommendations to help you master the key techniques for brewing multi-serving pour overs.

Many friends who enjoy pour over coffee often start practicing with a single serving: around 15 grams of coffee and 200 ml of water. But when you want to brew 2–3 cups at once to meet the needs of family or friends, your original small filter cone quickly becomes inadequate. This article conducts a real-world test using the V60 Size 02 large filter cone with 30 grams of coffee grounds. Starting from basic parameters, we gradually adjust grind size and water flow to find the most suitable brewing method for multi-serving portions.

Real Test Starting Point: Standard Parameters Yet Over-Extracted and Bitter

Following the common 1:15 coffee-to-water ratio, 30 grams of coffee grounds require 450 ml of water, with the water temperature set at 91°C, and using a three-pour technique (60/190/200). Initially, the same fine grind used for a single serving (80% passing through a #20 sieve) was used. The result was a total extraction time extended to 2 minutes and 53 seconds, and a clear sensation of over-extracted bitterness in the coffee. The root of the problem lies in the fact that increasing the coffee dose thickens the coffee bed, slowing down water flow and thus lengthening the overall extraction time, resulting in flavor imbalance.

Upgrade Your Filter Cone: Size 02 Is Suited for Larger Coffee Doses

A certain coffee brand’s past tutorials have mostly focused on 1–2 servings, using the Size 01 small filter cone, suitable for about 10–20 grams of coffee. But if you want to brew 30 grams, it is recommended to switch to the V60 Size 02 large filter cone, which is better designed to handle coffee doses over 20 grams, offering superior water drainage and coffee bed support. This real test is based on adjustments using the Size 02 filter cone.

Choosing Coffee Beans: Select Based on Flavor Preference

The flavor expression of pour over coffee depends not only on parameter adjustments but also on the coffee bean variety. If you prefer a low-acidity, full-bodied taste, you can opt for medium to dark roasted beans, such as Golden Mandheling or Blue Mountain No.1; for a coffee with rich layers and sweetness, Strawberry Candy or Colombian Sidamo are great choices; if you enjoy a fresh, fruity profile, consider medium-light roasted beans from Fruit Ding Ding Cooperative, Kafa Forest, or Geisha.

Second Real Test: Adjust Grind and Water Flow to Rescue Flavor

After identifying the over-extraction issue, we adjusted two key parameters: first, we slightly coarsened the grind size, reducing the #20 sieve passing rate from 80% to 75%, thereby decreasing the coffee bed’s water retention time; second, we increased the pouring water flow rate, recommending a speed of about 7–8 grams per second to ensure the total 450 ml of water could be poured within a reasonable time frame. The adjusted parameters were as follows: 30 grams of coffee grounds, 1:15 coffee-to-water ratio, 91°C water temperature, three-pour technique (60/190/200), anda water flow rate of 7–8g/sfor pouring.

The final real test showed the extraction time shortened to 2 minutes and 30 seconds, with flavor performance similar to that of a single serving brew—bitterness disappeared, layers became clear, and the fruitiness and body of the coffee were fully expressed.

Common Question: Can the Size 01 Filter Cone Brew 30 Grams of Coffee?

Some readers have asked: if you don’t have a Size 02 filter cone, can you use a Size 01 to brew 30 grams of coffee? The answer is:Technically possible, but not recommended. The Size 01 filter cone is originally designed for 10–20 grams of coffee. Using a larger dose with it can easily lead to a thick coffee bed and poor water flow, causing over-extraction or channeling, which negatively affects flavor. If you truly don’t have a Size 02, it’s better to brew in separate batches, or switch to another filter cone suitable for larger doses, such as the Kalita Wave 185.

With these real-test-derived parameters and techniques, whether for a family gathering or a small get-together with friends, you can consistently brew a balanced, layered 30-gram pour over using the V60 Size 02 filter cone, and enjoy the wonderful experience of shared coffee moments.
