Does rainy weather affect the sweetness of black tea?

Yes! Too much rain will have a great influence on tea.

Aroma, the aroma of tea is determined by the quality of tea. Generally speaking, the aroma of tea in autumn and summer will be higher, because the illumination time in autumn and summer is longer, the mineral components in tea are fuller and the water content is less.

Sweetness, too much rain will make tea water-filled, and there is no bitterness at the entrance, so it is not good to return to sweetness naturally, so tea is not resistant to soaking, which will reduce sweetness.
