Use this quick checklist to decide your next move.

• Repair: Water temp too high? Whisking in circles? Clumps? Sifting? → All free fixes. Try them first.
• Replace: Matcha older than 2 months? Whisk broken or too stiff? → Invest in a fresh small tin or a new whisk (under $10).
• Retire: Matcha tastes bitter, looks dull, or is culinary grade? → Let it go and buy ceremonial-grade from a trusted source.

If you're still unsure, ask yourself: Is the problem consistent, or does it happen sometimes? If it's intermittent, it's likely your technique or water temp that day. If it's every time, the powder or equipment is the weak link.
