Gentler on your gut, without compromising flavor or convenience.
If you're someone who loves coffee but finds yourself battling heartburn, bloating, or stomach discomfort after your daily cup, you’re not alone. Many coffee drinkers experience digestive upset, especially from traditional hot‑brewed varieties. But there’s good news: cold‑brewed instant coffee—like the kind made by Cusa—offers a smoother, gentler alternative without sacrificing bold flavor or your daily caffeine kick.
Let’s break down why cold‑brewed instant is better for sensitive stomachs and how Cusa’s patented process makes it even easier to enjoy coffee worry-free.
Hot-Brewed Coffee vs. Cold-Brewed: What's the Difference?
The biggest difference between traditional hot-brew and cold-brew coffee lies in how the coffee grounds are extracted. While hot water pulls out all the soluble compounds in coffee—including acids, oils, and bitter tannins—cold water extracts those compounds more slowly and selectively over time.
As a result:
-
Hot-brewed coffee tends to be more acidic, often irritating the stomach lining or triggering acid reflux.
-
Cold-brewed coffee is typically lower in acidity, resulting in a smoother taste and fewer digestive issues.
Studies show that cold brew can have up to 60–70% less acid than hot brew, making it a smart choice for people with GERD, IBS, or general stomach sensitivity.
Why Acid Matters for Digestive Health
Coffee contains chlorogenic acids and quinic acids—compounds that contribute to its signature brightness and bitterness. But these acids can also stimulate acid production in the stomach, which for some people results in:
-
Heartburn or acid reflux
-
Stomach cramps
-
Nausea
-
General gut discomfort
Low-acid coffee doesn’t mean low flavor—it means fewer compounds that aggravate the digestive system. That’s why cold brewing is a go-to for people looking to reduce symptoms without giving up their favorite morning ritual.
How Cusa’s Cold-Brew Process Takes It Further
At Cusa, we’ve taken traditional cold brew a step further with a patented process that’s:
-
Cold-brewed for 8+ hours, pulling out rich flavors while leaving behind the compounds that cause stomach irritation
-
Gently vacuum-dehydrated, preserving the taste, aroma, and integrity of each ingredient—without high heat, which can reintroduce bitterness or acidity
-
Additive-free and preservative-free, making our instant coffee as close to “just brewed” as possible
The result is a shelf-stable, instantly dissolvable coffee that’s low in acid, incredibly smooth, and ideal for people with sensitive stomachs.
