Editing Caffeinated drink (section)

===Tea===
Tea leaves contain more caffeine than coffee beans by dry weight. A typical serving, however, contains much less, since less of the product is used as compared to an equivalent serving of coffee. Also contributing to caffeine content are growing conditions, processing techniques, and other variables. Thus, teas contain varying amounts of caffeine.<ref name="FRI">{{cite journal|vauthors=Hicks MB, Hsieh YH, Bell LN |title=Tea preparation and its influence on methylxanthine concentration |journal=Food Research International |year=1996 |volume=29 |pages=325–330 |doi=10.1016/0963-9969(96)00038-5 |issue=3–4}}</ref>

Tea contains small amounts of [[theobromine]] and slightly higher levels of [[theophylline]] than coffee. Preparation and many other factors have a significant impact on tea, and color is a very poor indicator of caffeine content. Teas like the pale Japanese [[green tea]], ''[[gyokuro]]'', for example, contain far more caffeine than much darker teas like ''[[lapsang souchong]]'', which has very little.<ref name="FRI" />
