How Many Cups of Coffee in a 12 oz Bag? The Definitive Brew Guide
You’ve recently opened a 12 oz bag of coffee. You want to know how long is it going to last. Here’s the short answer: A typical 12 oz bag of coffee yields 17-24 cups of coffee.
It’s a promising sign, and a reasonable place to start. But the true answer is more complicated, and has to do with certain willful decisions we make as a society. The number of cups you receive will vary depending on how you brew it. It also depends on how strong you prefer your coffee. The size of your mug also matters, a lot.
You are the user and the product and this guide will walk you through the whole, wild thing. We will go over the major reasons that influence your cup total. We’ll let you in on a chart comparing brewing methods. We’ll even provide you with a personal calculator to help you determine your specific number. Let’s see how many cups of coffee are in a 12 oz bag for you.
The Simple Math: Understanding the Standard Yield
Now we just need to do a quick bit of math to determine the actual number of cups. It starts with an ounce-to-gram conversion. Grams is the preferred method for accurate coffee measurement.
There's approximately 340 grams of coffee beans in a 12 oz bag. That’s the number that was and is the most important to remember. An ounce is roughly 28.35 grams.
And now we need to talk about the “dose.” A dose is the volume of coffee grounds you use to make a single cup. Typically 15 to 20 grams for a normal sized cup is average. With that, we can perform a simple little calculation.
- 340 grams (total) / 20 grams (per cup) = 17 cups
- 340 grams (total) / 15 grams (per cup) = ~22.6 cups
This range is why you see different answers online. But coffee experts generally agree on this basic estimate. It's also helpful to know that a "standard" coffee cup is just 6 fluid ounces. Most of us drink from much larger mugs.
The 4 Key Factors That Change Your Cup Count
Now you have a linear basis. But perhaps things will play out differently for you. THESE four elements are what unlock great coffee every time. They will help you answer, “How many cups of coffee does a 12 oz bag make for my DIY routine?”
Factor 1: Brewing Method
A big part of how you brew your coffee matters. Various methods of brewing require different amounts of coffee to taste good. Each method also has its ideal ratio of coffee to water.
Espresso is very strong, for instance. It wastes a lot of coffee for a small amount of liquid. For a larger cup, however, a drip coffee maker or a French press uses a more moderate amount of grounds. Each technique imparts its own unique flavor. This affects your dose.
Factor 3: Your "Cup" Size
The word “cup” can create confusion. (Your coffee maker’s “cup” measurement is typically 5 or 6 fluid ounces.) But the one you actually drink from is probably 10, 12, or even 16 ounces.
It’s this size discrepancy that is a key factor making your bag feel like it runs out quickly. You may be opening and closing a flap when you fill your favorite mug up to two “technical” cups. Here’s how cup size affects your coffee needs:
- A 6 oz cup: Needs about 12 grams of coffee.
- An 8 oz cup: Needs about 16 grams of coffee.
- A 12 oz mug: Needs about 22 grams of coffee.
Factor 2: Brew Strength & The "Golden Ratio"
Do you like your coffee strong or on the lighter side? Your taste preference directly impacts how many cups you get. We measure this using the coffee-to-water ratio.
This is often called the "Golden Ratio." A common starting point is 1:16. This means you use 1 gram of coffee for every 16 grams (or milliliters) of water. If you prefer a stronger cup, you might use a 1:15 ratio. This uses more coffee and will give you fewer cups from the bag. A lighter cup at a 1:18 ratio uses less coffee. This stretches your bag further.
Cups Per Bag: A Brew Method Comparison Chart
For convenience, turned it into a chart. This gives you an approximate number of how may cups of coffee you’ll be able to make out of that 12 oz bag to produce, for varying brewing methods. For this comparison, we took an 8 oz cup of coffee as our standard.
As you can see, different brewing methods require different approaches to get the best flavor.
| Brew Method | Common Ratio | Dose for 8oz (227g) Water | Est. Cups from 12oz Bag |
| Drip Coffee Maker | 1:16 | ~14g | ~24 cups |
| Pour Over (V60) | 1:15 | ~15g | ~22 cups |
| French Press | 1:12 | ~19g | ~18 cups |
| AeroPress | 1:6 (Concentrate) | ~15g | ~22 cups (after dilution) |
| Espresso | 1:2 | 18g (for double shot) | ~18 double shots |
| Cold Brew | 1:8 (Concentrate) | ~28g | ~12 cups (of concentrate) |
We can see this difference very well by the graph. Drip coffee machines are highly productive. They give you the most cups. French Press brews the coffee in the water. It calls for a higher ratio and yields fewer cups. Cold brew requires a lot of coffee to produce a concentrate. Then water or milk is added to this.
Factor 4: Grind Size & Bean Density
Finally, the coffee itself matters. A very fine grind has more surface area.” This can result in pulling too much flavor out if you’re not careful. A rough grind may lack in flavor. This leads you to using more coffee to have that flavour in your coffee.
Bean density is also a minor factor. Dark roast beans are less dense and bigger than light roast beans. That means a scoop of dark roast coffee actually weighs less than a scoop of light roast. This is the best reason right here to weigh, a scoop would completely butcher this.

Now let’s proceed from estimates to your precise number. Here’s a quick, straight-forward method to determine your own yield. You can do this for every bag of coffee you purchase.
Your Roadmap: The 5-Step Process to Ordering Custom Printed Pouch Bags
The first time you order custom packaging can feel daunting. But when broken down, it’s a straightforward process. Here is an easy to follow map to get your own personalized printed stand up pouch bags.
Step 1: Weigh Your Coffee Dose
Grab your kitchen scale. For your next brew, measure exactly how many grams of coffee you use to produce a cup you love. Don’t have a scale? A typical coffee scoop holds about 10 grams. We find that our ideal morning mug (in the range of about 12 ounces) takes about 22 grams of a medium grind. Write down your number.
Step 2: Know Your Bag Weight
This one is easy. The starting weight for your 12 oz bag of coffee is 340 grams.
Step 3: Do the Simple Math
Now, just use this simple formula to find your total cups per bag.
340 / (Your dose in grams) = Total cups per bag
Putting It Into Practice: An Example
Let's walk through an example. Say you find that you love the taste of a pour over made with 18 grams of coffee.
The calculation is: 340 / 18 = 18.8.
You can expect to get nearly 19 cups from your 12 oz bag. It's that simple! Now you know exactly how much coffee you get for your money.
Coffee Bag Features that Make It Great
Do you want the most bang (and flavor!) for your buck? A few small tweaks in your routine can have a major impact. These tricks also minimize waste and improve the taste of your coffee.
First, don’t use a scoop; use a scale. By weight is much much more accurate than by volume. A scale means you are guaranteed to use the perfect amount every time. That helps you avoid wasting coffee that is too strong or too weak.
Second, grind your beans fresh. You see, pre-ground coffee is a perishable product, and it loses its taste and fragrance very fast. It’s tempting to load in more grounds to get the flavor you’re hoping for when your coffee tastes flat. Grinding right before you brew ensures the taste is at its brightest and fullest.
Finally, store your coffee properly. Oxygen and light are the enemies of fresh coffee. To preserve the delicate flavors and ensure you get the best out of every single gram, proper storage is crucial. Roasters invest heavily in high-quality coffee pouches with one-way degassing valves for this very reason. The quality of the initial coffee bags often indicates a roaster's commitment to freshness. For home storage, an airtight container kept in a cool, dark place is your best friend. This principle of protective packaging is vital across the food industry. It's a standard upheld by expert companies like YPAK COFFEE POUCH.
Frequently Asked Questions (FAQ)
We’ve come a long way. Here are responses to a few other frequently asked questions about making sure you’re getting the most out of your coffee.
There are a16 tbsp in an 8 oz (225 g) bag of coffee and a 12 oz(340 gm) has around 65-70 tbsp. That’s because 1 Tbsp of whole bean coffee is approximately 5 grams. Adjust this quantity according to the roast and grind. This is why we always tell you to measure with a scale?
Of equivalent weight, they produce the same number of cups. The 12 oz bag is also always 340 grams. But light roast beans are denser and smaller. (I am assuming you are measuring by volume, using scoops — if you do it by weight, you’ll get a little bit fewer cups from one light roast bag.) That’s because each scoop is heavier.
This is U depending on your coffee maker. Its “cup” size is typically 5 or 6 fluid ounces, not 8. A 12-cup pot usually requires 80-90 grams of coffee for a nice strength. For this reason, a 12 oz (340g) bag of coffee will get you about 3 to 4 full pots of coffee.
f you consume one 8 oz measure type cup of coffee a day, then you'll spend enough for a 12 oz bag, lasting you 3-4 weeks. That’s going to depend on the things we’ve discussed, such as brew strength. If you have two cups a day, one bag should last you for about a week and half 2 weeks.
The last best option, after weighing, is a standard coffee scoop. One level scoop is around 10 grams ground coffee or 2 level tablespoons. Take this as your stepping stone and adjust as per your preference. For an 8 oz mug, you might like 1.5 scoops.
