Description
Hicran Uzun Karka and Songul Kesen study how harvest season changes tea leaf traits in a 2026 report. Leaves were compared from May through September for water content, acidity, ash, colour, minerals, chemical fingerprints, aroma, and antioxidant strength. Tea quality in Turkey's Black Sea region depends heavily on such seasonal shifts.
Water content fell from 75.3 percent in May to 70.5 percent in September across the season in the reported values. Leaf brightness dropped as green pigment broke down. Potassium fell while calcium rose late in the season, and early leaves held more manganese and iron. Total aroma compounds peaked in July. Antioxidant strength fell from spring to autumn, backing the view that early harvests are richest.
