Do you have any experience with this?
The first time you walk into a tea shop or a tea counter, you will be greeted by a wide array of tea cans, and the salesperson will smile and say, \"This is a clear oolong, lightly fermented; this is a red water oolong, moderately fermented; and there is also black tea, fully fermented.
And you're like, \"What's fermented? Is it like sauerkraut? Or is it like the way wine is fermented?\" \ud83e\udd14<\/p>

Don't worry, today we are going to take a cup of tea to show you the \"fermentation degree\" of the tea -
It is not only a chemical change, but also a microcosm of culture and history, and the source of the \"personality\" of the cup of tea in your hand.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

  • fermentation<\/strong> \u2260 <\/strong>Alcoholic fermentation is actually the \"oxidized make-up\" of tea.<\/strong><\/li><\/ul>

    Let's get one thing straight:
    The \"fermentation\" of tea is not the fermentation of alcohol by yeast as in brewing wine or making bread, but--Enzyme-led oxidation within tea leaves<\/strong>\u3002<\/p>

    To put it simply, after the tea leaves are plucked, they go through the procedures we often hear about, such as withering, stirring, and ripening, which cause the cell walls inside the leaves to rupture, and the polyphenols inside begin to change under the action of \"polyphenol oxidase enzyme\", and as the degree of fermentation varies, the color changes from green to yellow to reddish-brown, and the aroma and taste change as well.<\/p>

    Think of it as a \"makeup show\":<\/p>

    • Green Tea \u2192 Totally Vegan Girl \ud83d\udc67, retains natural freshness.<\/li>

                                            Three,<\/strong>Fermentation brings about a change in taste sensation<\/strong><\/p>

                                            From a scientific point of view, tea polyphenols are converted into different substances during the fermentation process, which directly affects the taste:<\/p>

                                            • Green tea: most catechins \u2192 refreshing, but easily astringent.<\/li>
                                            • Oolong: Catechins are partially converted to different levels of theaflavins \u2192 floral and fruity aroma.<\/li>
                                            • Black tea: fully oxidized \u2192 theobromine-led \u2192 mellow and sweet.<\/li>
                                            • Black Tea: Post-fermentation to produce theobromine + various metabolites \u2192 warm and moist.<\/li><\/ul>

                                              So:<\/p>

                                              • Green tea is like the first sip of iced water in the morning, instantly sobering \ud83d\udca7<\/li>
                                              • Oolong smells like freshly baked toast \ud83c\udf5e<\/li>
                                              • The black tea is like caramelized milk, sweet and delicious \ud83c\udf6e\ud83e\udd5b<\/li>
                                              • Black tea is like a hot pot on a winter's night, warm and gentle \ud83c\udf72<\/li><\/ul>

                                                • the Ming (1368-1644) and Qing (1644-1911) dynasties<\/strong>The rise of stir-frying, the birth of oolong, and semi-fermentation became a specialty of the Southeast coast.<\/li>
                                                • Late Qing Dynasty 19th Century<\/strong>The British invented the \"Afternoon Tea\" after the black tea was exported to Europe in large quantities.<\/li>

                                                  Five,<\/strong>Common Myths:<\/strong><\/p>

                                                  1. Green tea is high in catechins and therefore highest in caffeine?<\/strong>
                                                    Not necessarily. Caffeine content depends on the variety, season, and process, not just the degree of fermentation.<\/li>
                                                  2. Is black tea \"milder\"?<\/strong>
                                                    Just because it is milder in taste does not mean it is low in caffeine, which is often the highest of all teas.<\/li>
                                                  3. Fermentation = healthier?<\/strong>
                                                    No, each type of tea has its own unique nutrients, it's just a matter of choosing the right time and amount.<\/li><\/ol>

                                                    Tea selection in life: What tea to drink when?<\/strong><\/p>

                                                    In fact, there is no need to get too entangled, just follow the timetable:<\/p>

                                                    • morning commuters<\/strong>A cup of green tea or a refreshing oolong is a great way to refresh and energize your mind.<\/li>

                                                      Conclusion: Fermentation is the soul of tea.<\/strong><\/p>

                                                      The beauty of tea is not just that it tastes good, but that it is fermented to give it an ever-changing personality.

                                                      When you understand fermentation, you will be able to find out the character of the tea in one sip: it can be as fresh as the morning sun, or as heavy as the evening sun; it can be as elegant as a white-clothed scholar, or as mellow as an old and wise man. \ud83d\udc49 \u300c<\/strong>Next time someone asks you that.<\/strong>\u8336<\/strong>How?
