The idea of “peak aging” is mainly about flavor maturity and balance. Many consider chenpi aged 5–15 years to be more stable in flavor, with 5–10 years often seen as the most balanced.
Flavor Changes by Age
- 3–5 years: citrus notes are still strong, bitterness more noticeable;
- 5–10 years: aroma becomes steadier, bitterness softens, taste is rounder;
- 10+ years: aroma is more restrained, mouthfeel softer, suited to those who prefer aged notes.
Overall, there is no absolute “peak.” The best age depends on personal taste and intended use.
