Tired of flat, sour cold brew? Mineral buildup is likely the culprit. Learn how to descale your cold brew maker with a simple vinegar routine that restores fresh flavor in minutes.

**Why Scale Ruins Cold Brew Flavor**  
Hard water leaves calcium and magnesium deposits inside the machine’s tubes and tank. Over time this scale alters brew temperature and extraction, leaving a flat or sour aftertaste. A quick rinse or dish soap won’t remove the crust; only a proper descaling solution will.

**Step‑by‑Step Vinegar Descaling Routine**  
First, empty any leftover coffee and rinse the carafe. Fill the water reservoir with a 1:1 mix of white vinegar and water (use 2:1 for heavy buildup). Run a brew cycle without coffee grounds, pausing halfway for about 15 minutes to let the acid work. Finish the cycle, discard the vinegar mix, then run two full water‑only brew cycles to rinse away any residual flavor.

**How Often Should You Descale?**  
If you use tap water daily, descale once a month to stay ahead of scale. Notice a change in taste sooner? Do it earlier. This routine is safe for seals and plastic parts, keeping your morning pour smooth and your wallet happy.
