"How many cups of coffee from 1kg beans?" It's a fair question that many coffee lovers ponder, especially those who brew their own coffee at home or run a cafe. Coffee is one of the most popular beverages in the world, and understanding how much coffee a certain amount of beans can produce will help you manage your coffee supplies better and ensure you never run out of your favourite brew.
Let's dive into this brew-tiful topic and sort out the facts from the froth.
Key Takeaways
-
On average, you can expect 60 to 100 cups of coffee from 1kg of beans.
-
The amount of coffee per 1kg bag of beans varies based on several factors.
-
Brewing methods, grind size, and personal preferences significantly impact coffee yield.
Understanding Coffee Bean Density and Types
First up, every coffee bean is different. The type of bean - whether it's Arabica or Robusta - can affect how many cups you'll get. Arabica beans are less dense than Robusta, which means you might get slightly fewer cups from 1kg of Arabica than Robusta.
The roast level also plays a part. Light roasts are denser than dark roasts because they retain more moisture. This means 1kg of dark-roasted coffee beans will take up more space than 1kg of light-roasted whole beans.
But don't get too caught up in this - the difference isn't massive.
Factors Influencing Yield
Several factors can influence how many cups of coffee you'll get from 1kg of beans:
-
Brewing method: Different methods use different amounts of coffee. An espresso machine typically uses more coffee per cup than a drip filter.
-
Grind size: A finer grind often means using less coffee, while a coarser grind for methods like French press might require more.
-
Cup size: Are we talking about a standard single-shot coffee, a takeaway cup, or a big mug? This makes a difference.
-
Personal preference: Some like it strong, others prefer it mild. This affects how many beans you use per cup.
Coffee-to-Water Ratio
Now, let's talk ratios. The standard coffee-to-water ratio for brewing coffee is about 1:15 or 1:16. This means for every gram of coffee, you're using 15-16 grams of water.
But here's the thing - this isn't set in stone. Your taste preference might lead you to use more or less coffee per cup.
Calculating Coffee Yield from 1kg of Beans
So, how many shots of espresso or cups of coffee can you yield from 1kg of beans? Let's break it down.
Standard Brew (Drip Coffee Maker)
-
Coffee Grounds Needed: 10-13 grams per 8oz (160-200ml) cup
-
Cups from 1kg:
-
Using 10 grams: 1000 grams / 10 grams = 100 cups
-
Using 13 grams: 1000 grams / 13 grams ≈ 77 cups
-
Espresso
-
Coffee Grounds Needed: 7-10 grams per single shot (30ml)
-
Cups from 1kg:
-
Using 7 grams: 1000 grams / 7 grams ≈ 142 shots
-
Using 10 grams: 1000 grams / 10 grams = 100 shots
-
-
Note: A cup of espresso-based drinks like lattes, cappuccinos, and americanos often use double or single shots as a base. So, if you use two shots of liquid coffee, you'll only get 50 to 70 cups.
French Press
-
Coffee Grounds Needed: 60 grams per litre (34oz)
-
Cups from 1kg:
-
1 litre = 5-6 cups (200ml per cup)
-
1000 grams / 60 grams ≈ 16.7 litres
-
16.7 litres * 5 cups/litre ≈ 83 cups
-
Cold Brew
-
Coffee Grounds Needed: 80 grams per litre of water
-
Cups from 1kg:
-
1 litre = 4 cups (250ml per cup)
-
1000 grams / 80 grams ≈ 12.5 litres
-
12.5 litres * 4 cups/litre ≈ 50 cups
-
Turkish Coffee
-
Coffee Grounds Needed: 10 grams per 60ml (2oz) cup
-
Cups from 1kg:
-
1000 grams / 10 grams = 100 cups
-
Moka Pot
-
Coffee Grounds Needed: 20 grams per 2-cup (120ml) pot
-
Cups from 1kg:
-
1 pot = 2 cups (60ml per cup)
-
1000 grams / 20 grams = 50 pots
-
50 pots * 2 cups/pot = 100 cups
-
AeroPress
-
Coffee Grounds Needed: 14-17 grams per 250ml (8.5oz) cup
-
Cups from 1kg:
-
Using 14 grams: 1000 grams / 14 grams ≈ 71 cups
-
Using 17 grams: 1000 grams / 17 grams ≈ 59 cups
-
Pour Over
-
Coffee Grounds Needed: 15-18 grams per 250ml (8.5oz) cup
-
Cups from 1kg:
-
Using 15 grams: 1000 grams / 15 grams ≈ 66 cups
-
Using 18 grams: 1000 grams / 18 grams ≈ 55 cups

Tips for Maximising Coffee Yield
Want to get the most out of your 1kg bag of beans? Here are some tips:
-
Proper Storage: Keep your coffee beans fresh by storing them in an airtight container away from light, heat, and moisture.
-
Accurate Measurements: Use a kitchen scale to measure your coffee beans accurately.
-
Experiment with Grind Sizes: Find the sweet spot between coffee flavour and yield.
-
Reduce Wastage: Ensure your grinder is well-calibrated to minimise losses.
Practical Advice for Coffee Enthusiasts
If you're buying coffee beans in bulk, consider how quickly you'll use them. Green beans weigh more and last longer than roasted coffee beans, but they require roasting at home. For most folks, buying roasted beans in smaller batches ensures freshness.
If you're planning to open a cafe or are just serious about your coffee, investing in quality coffee equipment such as bean grinders and espresso machines can make a huge difference. Freshly ground coffee tastes much better than pre-ground, and having control over the grind size allows you to optimise your brew.
When it comes to taste, don't be afraid to adjust. If you find your brew too strong, use less coffee next time.
Too weak? Chuck in a few more beans. It's all about finding your perfect balance.
Final Thoughts
So, how many cups of coffee can you get from 1kg of beans? The answer isn't straightforward, but you can expect around 60 to 100 cups of coffee. Remember, this can vary based on your brewing method, grind size, cup size, and taste preference.
The main thing is to enjoy your coffee experience. Whether you're pulling shots on an espresso machine or using a cold press, the perfect cup is the one that tastes right to you.
