Listen up: If you’re chasing that perfect cup of coffee, you’ve probably wrestled with the mess of RO water mineral balancing. The Barista Hustle method—buffer and hard water bottles—works, but it’s a pain. Juggling multiple 1-liter containers, measuring 20-60 grams per brew? It’s a recipe for frustration. Enter the concentrate hack: mix bicarb and epsom salt into a mason jar, dilute to 10x strength, then add 10ml per liter at brewing time. It’s genius in theory, but here’s the catch—minerals precipitate out after a few days, leaving crystallized sludge in your jar. Now you’ve got a science experiment and a mess to clean.
The fix? Store your concentrate in the fridge. Aramse’s advice hit the mark: chill the mix to keep minerals dissolved. My new formula? 8g epsom salt, 3.8g bicarb, 189ml RO water. Blend it, refrigerate, and pull 4ml per liter of brew. No more guessing games. The fridge slows mineral fallout, and the syringe makes dosing precise. Still, the real trick is balancing minerals for extraction—too much bicarb, and you’ll taste chalk; too little, and your coffee lacks body.
This method isn’t just about convenience. It’s about control. You’re not just adding minerals—you’re crafting a water profile that unlocks your beans’ potential. The key? Start small. Test ratios, tweak based on your brew’s flavor, and don’t skimp on the fridge step. If you’re cheap and crave simplicity, this is your shortcut.

Questions & Answers
How does a reverse osmosis system work?
RO systems use a semi-permeable membrane to filter water. Pressure pushes contaminants through the membrane, leaving clean water on one side. It removes ions, bacteria, and impurities effectively.
What are the benefits of RO water?
RO water is pure, safe for drinking, and free from harmful substances. It improves taste and is ideal for cooking, brewing, and medical uses. It also reduces reliance on bottled water.
