While white teas are "less processed" than greens, they are actually usually more somewhat more oxidized. Mild oxidation occurs during the "wilting" stage, when white tea is air-dried after it is first picked. White tea is then baked and dried further, and it may be very lightly rolled, but little is done to change what was picked from the plant. One way to tell that white tea is slightly oxidized is that white teas don't usually need to be steeped as carefully as greens. Steeping white tea with boiling water or for longer time periods can still produce good results.
