Brewing coffee at home sounds easy — just add water and coffee, right? But if your coffee sometimes tastes bitter, sour, or flat, you might be making a few simple mistakes. Don’t worry, even the biggest coffee lovers do!

In this guide, we’ll walk you through the 5 most common coffee brewing mistakes and show you how to fix them — so you can enjoy a café-quality cup every single morning.

1. Using the Wrong Coffee-to-Water Ratio

Getting the coffee-to-water ratio right is the first step to great coffee. Using too much coffee makes it bitter, while using too little makes it weak and watery.

The Fix:
Follow the Golden Ratio — 1 to 2 tablespoons of coffee for every 180ml (6oz) of water.
If you like a stronger cup, add slightly more coffee — but don’t overdo it.

2. Brewing with the Wrong Water Temperature

Water temperature has a major impact on your coffee’s flavor. If it’s too hot, the grounds can burn; if it’s too cool, the coffee won’t extract properly and will taste sour.

The Fix:
Keep your water between 90°C and 96°C (195°F–205°F). If you don’t have a thermometer, just boil your water and let it sit for 30 seconds before brewing.

 

3. Grinding Coffee the Wrong Way

The size of your coffee grounds is crucial to the quality of your brew. If your coffee tastes sour, your grind might be too coarse; if it’s bitter, it might be too fine.

The Fix:
Match your grind size to your brewing method:

Always grind fresh beans just before brewing for the best flavor and aroma.

4. Using Tap Water Without Filtering It

Water makes up 98% of your coffee, so its quality directly affects taste. Tap water in the UAE can sometimes have minerals or chlorine that change the flavor.

The Fix:
Use filtered or bottled water for a smoother, cleaner cup.
If your coffee tastes metallic or salty, your tap water might be the reason.

5. Ignoring Brew Time

The amount of time coffee and water stay in contact determines extraction. Brew too quickly, and your coffee will be sour; too long, and it will be bitter.

The Fix:
Stick to these brew times:

Use a timer — it’s a small step that makes a big difference!

Bonus Tip: Store Your Coffee Properly

Even if you fix everything else, stale coffee beans can ruin the taste.
Keep your coffee beans in an airtight container, away from light, heat, and moisture. Never store them in the fridge — it kills the aroma!
