What happens when a world-class coffee roaster partners with a leader in water innovation? You get a collaboration that transforms your daily brew into something extraordinary. Delta Faucet and Helm Coffee have teamed up to show how water quality can make or break your coffee—and why the Delta® Clarifi™ Reverse Osmosis System is the ultimate upgrade for coffee lovers.
Why Water Quality Matters in Coffee
Did you know that coffee is 98% water? That means the water you use is just as important as the beans you brew. Think of water as the seasoning in your favorite dish. Too many minerals and your coffee can taste bitter, too few and it can taste flat. To get the best tasting coffee, you want balanced water that enhances flavor without overpowering it.
As Justin, Helm Coffee's roast master and 2025 U.S. Brewers Cup Champion, puts it:
"A truly excellent cup of coffee starts with three things: great beans, a solid recipe, and good water."
The Delta Clarifi™ Reverse Osmosis Advantage
So how do you get that perfect water? That's where our Delta Clarifi™ Reverse Osmosis System comes in. It reduces impurities and minerals from your tap water, giving you a clean slate. Then you can use the remineralization cartridge to add back just the right amount of magnesium and calcium—minerals that make coffee flavors pop.
Justin explains it best:
"Reverse osmosis gives us a baseline. From there, remineralization creates a dance of acidity, sweetness, and mouthfeel. It's what takes a good cup and makes it exceptional."
The result? A cup that's vibrant, balanced, and true to its origin—whether you love fruity Ethiopian notes or rich chocolate tones.
Why Helm Coffee Trusts Delta Faucet for Perfect Brewing Water
Helm Coffee needed a water solution that could handle Indiana's hard water while giving them control over flavor. Our Delta® Clarifi™ Reverse Osmosis System delivered:
- Consistent water quality for every brew
- Tankless design for easier maintenance
- Flexible remineralization for flavor customization
"It's been amazing to partner with Delta Faucet," Justin says. "We share a passion for craftsmanship and community, and this collaboration lets us showcase both."
How to Brew Café-Quality Coffee at Home
While we highly recommend stopping by Justin's coffee shop in Indianapolis—or your favorite local spot, you can easily make café-quality coffee at home. Here are Justin's top tips for home brewers:
1. Start with Great Water
Good water is the foundation. The Delta® Clarifi™ System can be installed in any home and ensures every cup starts clean and balanced. Add a beverage faucet to your kitchen for fresh, clean water on demand.
2. Use Fresh, Quality Beans
Look for specialty coffee from trusted roasters. Freshness matters. Ideally, you'd grind your beans fresh each time, but hey, sometimes you need your coffee ASAP.
3. Invest in the Basics
- A pour-over brewer for simplicity
- A gooseneck kettle for precision
- A scale for consistency
- A burr grinder for even extraction
4. Experiment and Enjoy
Change one variable at a time—grind size, water temperature, or brew ratio—and taste the difference.
