Why does chrysanthemum tea taste bitter? Understanding the science behind the flavor

4 min read

According to scientific research, high concentrations of natural flavonoids and other phenolic compounds found in dried chrysanthemum flowers are a primary reason why chrysanthemum tea can taste bitter. This floral brew's flavor is a complex mix influenced by both its inherent compounds and how it is prepared.

Quick Summary

The bitter taste in chrysanthemum tea can be caused by its natural flavonoid and phenolic compounds, over-steeping, using water that is too hot, or low-quality flowers. Adjusting brewing parameters can result in a sweeter, more pleasant floral flavor.

Key Points

  • Chemical Causes: The bitterness in chrysanthemum tea is due to natural flavonoids and phenolic compounds, particularly when over-extracted.

  • Brewing Matters: Over-steeping and using water that is too hot are the most common causes of bitterness in home-brewed tea.

  • Flower Quality: The variety and freshness of chrysanthemum flowers significantly impact flavor, with wild varieties often being more bitter.

  • Adjust and Balance: Cooler water (190-200°F) and shorter steeping times (5-7 minutes) prevent the release of excessive bitter compounds.

  • Sweeten Naturally: Adding sweeteners like honey, rock sugar, or goji berries can effectively balance and counteract the tea's bitter notes.

  • Control Extraction: Using an infuser or removing the flowers after steeping is crucial to prevent the tea from becoming progressively more bitter over time.

The Chemical Culprits Behind the Bitterness

To understand why your chrysanthemum tea might taste bitter, one must delve into its chemical composition. Like many plants, chrysanthemums contain a variety of compounds that contribute to their flavor, aroma, and medicinal properties. While many find the subtle, floral sweetness appealing, certain compounds can overpower the palate with a bitter or astringent sensation if not handled correctly.

Natural Flavonoids and Phenolic Acids

The most significant contributors to bitterness in chrysanthemum tea are flavonoids and phenolic acids.

  • Flavonoids: Compounds like luteolin and apigenin are abundant in chrysanthemum flowers and are known to contribute to both bitterness and astringency. These compounds have antioxidant and anti-inflammatory properties, but their taste profile can be overwhelming in high concentrations.
  • Phenolic Acids: Substances such as chlorogenic acid and isochlorogenic acid are also found in chrysanthemum and are easily extracted during brewing. These can enhance acidity and contribute to a more complex flavor that some perceive as bitter.

L-Phenyllactic Acid

Less commonly known but equally important is l-(-)-3 phenyllactic acid, identified in a metabolomics study as a key metabolite specifically correlated with the 'bitterness' attribute in some varieties of chrysanthemum tea.

Brewing Technique: A Major Influencer

Beyond the natural composition of the flowers, your brewing method is a critical factor in determining the final taste. Improper technique is a common reason for a surprisingly bitter cup.

Water Temperature

Using boiling water is one of the quickest ways to ruin a cup of chrysanthemum tea. The high heat over-extracts bitter compounds, releasing them far too quickly and in excessive amounts. The ideal temperature range for brewing is typically between 190–200°F (88–93°C).

Steeping Time

Leaving the flowers to steep for too long is another cause of bitterness. While a longer steep can yield a stronger flavor, it also allows more time for the bitter flavonoids to dissolve into the water. A steeping time of 5 to 7 minutes is often recommended for a balanced brew, but this can be adjusted based on personal preference and the specific flower variety.

Comparison of Brewing Methods

Brewing Aspect Proper Technique Improper Technique
Water Temperature 190–200°F (88–93°C) Boiling (212°F / 100°C)
Steeping Time 5–7 minutes 10+ minutes (or forgotten)
Flower Quantity 1 tsp per cup Too many flowers per cup
Resulting Flavor Mild, floral, slightly sweet Overly bitter, strong, and astringent

Quality and Variety of Flowers

Not all chrysanthemum flowers are created equal. The specific variety and quality of the flowers you use can have a profound effect on the final taste.

  • Wild Chrysanthemums: Some wild or uncultivated varieties are naturally grassier and can produce a more intensely bitter tea, especially if steeped for a long time.
  • Cultivated Varieties: Different cultivated species, such as Chrysanthemum morifolium, are bred for specific flavor profiles. High-quality, fresh, and carefully processed flowers typically yield a sweeter, more pleasant cup without overwhelming bitterness. If you purchase fully opened flowers, you may find they have already lost much of their optimal flavor.

How to Fix and Prevent Bitter Chrysanthemum Tea

Here is a list of actionable tips to ensure your tea is perfectly balanced and not bitter:

  • Use the Right Water Temperature: Always allow boiling water to cool for a minute or two before pouring it over the flowers. This single step can make a world of difference.
  • Mind Your Steep Time: Use a timer to avoid over-steeping. If you accidentally leave the flowers in too long, simply remove them to prevent further extraction of bitter compounds.
  • Adjust Your Ratios: Don't use too many flowers for the amount of water. If you want a stronger brew, increase the flower-to-water ratio slightly, but also be mindful of steeping time.
  • Add Sweeteners: For those who prefer a sweeter taste, adding rock sugar, honey, or goji berries is a traditional and effective method.
  • Rinse the Flowers: A quick initial rinse of the dried flowers before brewing can help remove any surface dust or debris, which might also impact the flavor.
  • Source High-Quality Flowers: Invest in reputable brands that sell fresh, high-quality, whole chrysanthemum blossoms for a superior flavor profile. Learn more about the health benefits of chrysanthemum tea from reliable sources(https://www.webmd.com/diet/health-benefits-chrysanthemum-tea).
  • Experiment with Blends: Try blending chrysanthemum flowers with other ingredients that complement their flavor, such as goji berries, dates, or even green tea, to balance the taste.

Conclusion: Achieving the Perfect Cup

The bitter flavor in chrysanthemum tea is not a flaw but a natural characteristic, influenced by chemical compounds and brewing methods. By carefully controlling water temperature, steeping time, and sourcing quality flowers, you can unlock the delicate floral aroma and subtle sweetness that the tea is celebrated for. Don't be discouraged by a bitter first brew; by experimenting with the tips above, you can master the art of making a perfectly balanced and soothing cup of chrysanthemum tea.

Frequently Asked Questions

The main compounds responsible for bitterness are natural flavonoids like luteolin and phenolic acids such as chlorogenic acid, which can be over-extracted during brewing.

You should avoid using boiling water. It is best to let the water cool slightly to a temperature between 190–200°F (88–93°C) to prevent the over-extraction of bitter compounds.

You can reduce bitterness by using cooler water, shortening the steeping time, or adding a natural sweetener like honey or rock sugar to balance the flavor.

Yes, different varieties have distinct flavor profiles. Wild chrysanthemums, for example, may have a grassier, more bitter taste, while cultivated varieties are often sweeter and more delicate.

Yes, it is perfectly safe to drink. Bitterness is a result of over-extracted natural compounds and does not indicate that the tea is harmful, though the flavor may be less pleasant.

It is a good practice to give the dried flowers a quick rinse with cold water to wash away any dust or impurities before steeping.

A steeping time of 5–7 minutes is a good starting point. You can adjust this duration to match your preferred strength, but longer steeping will increase bitterness.

Yes, high-quality chrysanthemum flowers can often be re-steeped several times. The flavor will become milder with each infusion.
