How Water Impacts Your Filter Kaapi

When was the last time you thought about the water you’re using to make a cup of South Indian filter kaapi?

Brewing good kaapi is not just about using the right coffee beans. Water plays a huge role in the quality and taste of your kaapi. Even the smallest change in the water can influence kaapi’s aroma, flavour notes, and texture.

Wondering how? Keep reading to know how water impacts your filter kaapi.

Why Water Matters More Than You Think

In most cases, water makes up a significant part of the cup.

As the foundation of your brew, it’s responsible for pulling flavour out of ground coffee and ensuring these flavour notes can be experienced when you take a sip.

If the water you use is well-balanced in its composition and of the right temperature, you’ll get coffee that is rich, full-bodied, and smooth. On the other hand, if you use water that’s of poor quality, the same coffee can taste bitter or flat.

The Role of Water Quality in Taste

To put it simply, using clean, fresh water is always better when you’re brewing kaapi. It brings out the natural flavours in the beans.

Water that has a strong chlorine or chemical taste will significantly influence how your kaapi tastes, so it’s best to avoid those.

When you’re making kaapi at home, use filtered water. There’s no need for fancy gear. A basic water filter will make a big difference. That said, if the tap water at your home is good and tastes clean, you can also compare how coffee made with tap water tastes.

Hard vs Soft Water

The minerals present in water determine whether it’s hard water or soft water.

Hard water has more minerals than soft water; regardless, they can both negatively influence the taste of your kaapi.

Hard water can make the coffee taste heavier and sometimes dull the flavours. Whereas, soft water makes it lighter, but it can also result in your kaapi tasting weak.

While you may not be able to test the exact composition of minerals in your water at home, what you need to remember is that if the water you drink daily tastes balanced, it’ll likely produce a good cup of kaapi too.

Temperature

Just like mineral composition, the temperature of water also affects extraction.

If the water is too hot, it’ll over-extract the coffee. That means the water will pull out more soluble compounds from the coffee than it’s supposed to. This will give you kaapi that tastes bitter.

On the flip side, water that’s not hot enough or is cool will not have the strength to extract the right amount of flavour from the grounds. If your kaapi tastes flat and not flavourful, this could probably be the cause.

A basic guideline you can follow is to let the water boil and then sit for 20-30 seconds so that the temperature is just right for brewing kaapi.

Small Changes, Better Kaapi

To wrap up this blog post, here are 3 quick tips:

Use fresh water each time you make filter kaapi. Avoid water that has been stored in a container for a long time or water that has previously been boiled. Reboiling water multiple times will affect your coffee.
When you’ve figured out which water is better for brewing coffee, stick to it. Changing the water source will also change the taste you’ve grown to like and lead to inconsistent cups of kaapi.
If your filter kaapi doesn’t taste the way it’s supposed to, adjust the brew slowly by just changing the water first and leaving all other variables the same.
