Best Water for Espresso Machines: Purified Third Wave Tips

Not just any water — the right water.

Whether you’re a home barista or running a small café, the water for espresso machines you use can make or break your coffee. Let’s talk about why.

Coffee Is Mostly Water — So It Should Matter More

Here’s something that puts things in perspective: espresso is about 90–95% water. That means the coffee water you use doesn't just dissolve the grounds — it directly shapes the flavor.

Tap water might be fine for boiling pasta, but for espresso? Not really. It often contains chlorine, too much calcium, or random minerals that ruin the taste. Worse, it can leave mineral deposits that clog your espresso machine water lines.

Ever brewed coffee that tasted flat, bitter, or just weird — even with great beans? Yep. That’s your water talking.

So What Kind of Water Should You Use?

You don’t want water that’s too hard or too soft. Here’s the quick breakdown:

• Hard water (full of minerals) = scale buildup and dull flavor
  
  

• Soft or distilled water (no minerals) = under-extracted coffee and potential machine issues
  
  

The goal is to find balance — purified water that’s been re-mineralized just right for espresso.

What Is Third Wave Water?

This is where Third Wave Water espresso coffee comes in. It’s a simple concept: you take distilled or reverse osmosis water, add a small packet of minerals, and boom — you have perfect coffee water for brewing.

Specifically, the Third Wave Coffee with Purified Mineral Water approach helps:

• Extract flavors more cleanly and consistently
  
  

• Prevent scale in your espresso machine
  
  

• Let your beans shine, especially with lighter roasts
  
  

It’s not a gimmick. It’s just smart chemistry — and it’s changed the way many baristas brew.

Tips for Better Espresso Machine Water

1. Don’t use straight tap water. It’s unpredictable and often full of chlorine or excess minerals.
   
   

2. Avoid plain distilled water. It lacks the minerals needed for extraction and can harm certain boilers.
   
   

3. Use distilled/RO + minerals. This combo gives your machine exactly what it needs.
   
   

4. Maintain your machine. Even with the best water, regular cleaning is key.
   
   

By using the right water for espresso machines, you not only improve flavor but also extend your machine’s life.
