Good chenpi usually has restrained acidity and bitterness with a clear aged citrus aroma and balanced aftertaste. It should be judged by aroma, bitterness, and lingering sweetness together.
Flavor Differences by Age
- 1–5 years: more direct citrus notes with stronger acidity and bitterness;
- 5–10 years: clearer citrus aroma and a softer taste;
- 10–20 years: richer aged aroma and fuller mouthfeel;
- 20+ years: steadier aroma with a longer finish.
Overall, higher age often means more mature flavor, but storage condition and personal preference still matter.
