How Much Coffee for 12 Cups? The Perfect Brew Guide
Share
If you're making a large batch of coffee for guests, the office or a family gathering, you may be wondering: how much coffee for 12 cups is the right amount?
Getting the ratio correct ensures your coffee is flavourful, balanced and never bitter or weak.
Here’s the simple formula you can trust every time.
How Much Coffee Do You Need for 12 Cups?
Most coffee makers count 1 “cup” as 5–6 oz (150–180ml) — not a full mug.
Based on the standard Golden Ratio (1–2 tablespoons of coffee per 6 oz of water), here’s the measurement:
✅ For 12 cups of coffee: use ¾ cup (approx. 90g) of coffee grounds.
This equals around:
-
12 tablespoons of coffee (1 tbsp per cup), or
-
90g of coffee (if using scales)
If you prefer a stronger brew:
🔥 For stronger 12 cups: use 1 cup (around 120g) of coffee grounds.
Standard Ratio for Any Size Batch
If you want to calculate it yourself:
1 tablespoon (or 7–8g) of coffee per “cup” of water
So for 12 cups → 12 tablespoons → approx. 90–100g.
Using scales is always more accurate, especially with specialty beans.

Does Grind Size Affect How Much Coffee You Should Use?
Yes — grind size changes extraction:
-
Coarse grind → weaker extraction → may require slightly more coffee
-
Medium grind → ideal for drip coffee makers
-
Fine grind → stronger extraction → use cautiously
For drip machines, stick with a medium grind for best results.

How Much Water Do You Need for 12 Cups?
If your machine measures its own water, simply fill it to the 12-cup line.
Otherwise, measure:
12 cups = approx. 1.9 litres of water
Filtered water is best — it improves flavour and protects your machine.
Tips for Brewing 12 Cups of Delicious Coffee
1. Use fresh, high-quality beans
The larger the batch, the more noticeable low-quality beans become.
Try single-origin options like:
2. Brew immediately after grinding
Freshly ground beans give a stronger aroma and smoother taste.
3. Don’t let coffee sit on a hot plate too long
It becomes bitter after 20–30 minutes.
Use a thermal carafe if possible.
What If You're Using a French Press or Pour-Over?
These methods require slightly different ratios.
