What is the difference between freshly brewed tea and aged tea that has been stored for several years

Freshly produced ripe tea (new tea):
At this stage, the aged tea still carries the lingering intensity from the fermentation process, resulting in a somewhat astringent and dry taste—like freshly roasted nuts, leaving the throat feeling parched.
The flavor tends to be somewhat subdued and lacks depth, leaving a sense of incompleteness when sipped. The sweetness isn't as pure and refreshing as that of aged tea, only hinting faintly—overshadowed by a distinct "fermented aroma." To put it bluntly, this aroma resembles the scent of damp wood, haystacks, or a traditional Chinese medicine shop—unappealing, yet unavoidable for fresh tea.
In terms of taste, it achieves a balance of neither bitterness nor astringency, but the dryness is quite pronounced—after drinking, the tongue and throat feel slightly dry and tight. There is some smoothness, but it falls far short of being mellow and velvety, and the sweetness is not fully developed.

After several years of aging, the raw taste of ripe tea fades away over time, revealing its true flavor
Aroma: The initial floral notes fade, evolving into woody and aged scents. Higher-quality varieties may develop hints of jujube, glutinous rice, or honey, becoming more profound and grounded.
Flavor: The thickness increases, with a full-bodied tea infusion that delivers a clearer sweetness—like that of sugar cane juice—keeping the palate consistently moist.
Neither bitter nor astringent (this is the most notable characteristic of ripe tea, as it causes minimal irritation to the stomach and intestines)
Rich and smooth (like drinking rice soup, with no resistance in the throat)
Sweet, warm, sticky, and fragrant (the sweetness is mellow and soothing, while the fragrance is deep and grounded, not floating)
For beginners, it's recommended to start with aged ripe tea (3-5 years old), as it's at its peak flavor. If you detect a strong sour, rancid, or moldy taste, it's unpleasant and indicates issues with craftsmanship or storage—stop drinking it immediately.
