Some things will ruin your matcha completely. Avoid these at all costs:
- Dishwasher: Never put your chawan or chasen in the dishwasher. The heat and detergent will warp the whisk and crack the bowl. Hand wash only.
- Boiling water: This is the number one mistake. It turns your matcha bitter and flat. Always cool the water first.
- Stale matcha: If your tin has been open for months, the leaves have oxidized and lost their flavor. BrewNova matcha is best within 30–60 days of opening. If it smells like grass clippings, it's past its prime.
- Cross-contamination: If someone uses your whisk to stir their instant coffee, that's game over. The whisk fibers will absorb the coffee oils, and no amount of rinsing will get them out. You'll need a new whisk.
These aren't negotiable. They're the difference between a bright, sweet cup and a sad, bitter one.
