When brewing high-quality Chenpi, you might find it wasteful to discard the peel after only a few infusions and consider keeping it for the next day. But is overnight Chenpi tea safe? Here is an in-depth analysis of the health risks involved.
Why You Should Avoid Overnight Chenpi Tea
Although Chenpi differs from regular green tea, leaving it overnight poses two main risks:
- Deteriorated Taste and Bitterness: Polyphenols in Chenpi undergo slow oxidation during prolonged soaking and exposure to air. This causes the tea color to darken and turn cloudy, and more importantly, it develops a heavy bitterness. Drinking it may irritate the throat and cause discomfort.
- Risk of Bacterial and Mold Growth: Chenpi contains natural sugars. Leaving it at room temperature for a long time makes it a breeding ground for bacteria and mold. Consuming overnight water contaminated with mold can lead to food poisoning, resulting in symptoms like abdominal pain, vomiting, and diarrhea.
How to Properly Save Steeped Chenpi?
If you don't want to waste high-quality Chenpi steeped during the day, try these methods:
- Refrigeration: Discard the water, place the wet Chenpi in a clean container, and store it in the refrigerator. The low temperature inhibits bacterial growth. You can take it out the next day for re-brewing.
- Secondary Use (Cooking): Even if the flavor for tea has faded, the aged fragrance remains. You can scrape off the inner pith, shred it, and add it to congee, soups, or stews. Chenpi is excellent for removing gaminess and greasiness in meat dishes.
Daily Drinking Reminders
- Material Safety: Never use moldy or spoiled Chenpi for brewing, as it can severely damage liver and kidney functions.
- Temperature Control: Do not use extremely hot water that might destroy active components. Water around 90°C is generally ideal.
Summary: For health reasons, drinking overnight Chenpi tea is not recommended. If you wish to save the peel itself, ensure you discard the tea water and refrigerate the peel.
