Caffeine in Drinks

Yellow Tea

Yellow Tea or Yellow Bud Tea is made from the leave buds of the Camellia sinensis plant.

The leaves are then processed in a similar fashion to green tea, but the leaves are kept damp until they yellow slightly. This slight fermentation removes the grassy flavor of green tea, yet retains most of green tea's health benefits.

Some people prefer the flavor of yellow tea because it is somewhere between green tea and black tea.

2009 research found the caffeine content of yellow tea to be 3.18%. So, 1 gram of yellow buds yields around 32 mg of caffeine.  This is more caffeinated than black and green tea.

A 2 gram bag of yellow tea (what is typically steeped in 1 cup of hot water) would yield around 64 mg caffeine. Note that the amounts vary due to source, blend, and brew time.

However, processing also affects how much caffeine actually is released during brewing. There haven't been extensive tests on yellow tea, but we estimate the caffeine content to be somewhere between green and black tea.
