How much coffee to use for 12 cups: Brewing the Perfect Pot

The perfect cup of coffee begins with the perfect amount of coffee grounds. Finding the right balance of coffee to water can be a daunting task, especially if you’re brewing coffee for a large group. In this article, we’ll show you how much coffee to use for 12 cups to achieve that perfect pot every time.

Understanding Coffee Measurements

Before we dive into the amount of coffee needed to brew 12 cups, it’s essential to understand coffee measurements. Coffee is measured by weight, with one standard coffee scoop, or tablespoon, equal to approximately 7 grams of coffee.

It’s also important to note that coffee is brewed using a ratio, typically ranging from 1:15 to 1:18. This ratio describes the weight of coffee to the weight of water used during the brewing process. For example, a 1:15 ratio means using 15 grams of water per gram of coffee. A ratio of 1:18 would mean using 18 grams of water per gram of coffee.

How Much Coffee to Use for 12 Cups: The Formula

So, how much coffee should you use for 12 cups of coffee? The answer lies in the ratio. Most coffee experts recommend a ratio of 1:15, which means using 15 grams of water per gram of coffee. With 12 cups of coffee, you’ll need 1.5 cups or 360 milliliters of water per 60 grams of coffee.

Using the recommended 1:15 ratio, we can calculate the amount of coffee needed for 12 cups using the following formula:

Number of Cups Water (ml) Coffee (g)
12 3600 240

Based on this formula, you’ll need 240 grams of coffee beans for 12 cups of coffee.

Choosing the Right Grind Size

The amount of coffee is only one factor in brewing the perfect pot. The grind size of your coffee also plays a critical role in the final taste of your coffee. Grinding your coffee too finely can lead to an over-extracted, bitter taste, while grinding it too coarsely can result in a weak, sour taste.

For a standard drip coffee maker, a medium grind is recommended. This size will allow for optimal extraction without over-extracting the coffee. If using a French Press, a coarser grind is recommended.

Additional Tips for Brewing the Perfect Pot

Use Fresh, Quality Coffee Beans

The quality of the coffee beans you use is essential. Always opt for fresh, high-quality beans and avoid using pre-ground coffee, as it can become stale quickly.

Use Clean Equipment

Regularly cleaning your coffee maker or French Press is crucial in producing a clean, flavorful pot of coffee. Clean your equipment with vinegar or a coffee-specific cleaner regularly.

Consider Water Temperature

The optimal brewing temperature for coffee is between 195 and 205 degrees Fahrenheit. If your water is too cold, you’ll under-extract the coffee, resulting in a weak, sour taste. If the water is too hot, it can lead to over-extraction and a bitter taste.

Measure Carefully

Using a kitchen scale to measure your coffee and water will ensure that you are accurately following the 1:15 ratio, resulting in a balanced and flavorful pot of coffee.


Brewing the perfect pot of coffee isn’t difficult. With the right amount of coffee, water, and attention to detail, you’ll have a flavorful pot in no time. Keep in mind the recommended 1:15 ratio, choose the right grind size, and use quality beans, clean equipment, and the proper water temperature. With these tips, you’ll be well on your way to achieving the perfect pot every time.
