The standard has been disputed, particularly by producers from Guangdong. Cultivated tea bushes, from the seeds or cuttings of wild tea trees and planted in relatively low altitudes and flatter terrain. The tea produced from these plants are considered inferior due to the use of pesticides and chemical fertilizer in cultivation, and the lack of pleasant flavors, and the presence of harsh bitterness and astringency from the tea.

These trees produce teas of better flavor due to the higher levels of secondary metabolite produced in the tea tree. As well, the trees are typically cared for using organic practices, which includes the scheduled pruning of the trees in a manner similar to pollarding.

Despite the good quality of their produced teas, "wild arbor" trees are not as prized as the truly wild trees. Such teas are valued for having deeper and more complex flavors, often with camphor or "mint" notes, said to be imparted by the many camphor trees that grow in the same environment as the wild tea trees.

Different tea factories have earned good reputations. Menghai Tea Factory and Xiaguan Tea Factory, which date from the s, have enjoyed good reputations, but in the twentyfirst century face competition from many of the newly emerging private factories.

However, due to production inconsistencies and variations in manufacturing techniques, the reputation of a tea company or factory can vary depending on the year or the specific cakes produced during a year.

Recipes[ edit ] Tea factories, particularly formerly government-owned factories, produce many cakes using recipes for tea blendsindicated by a four-digit recipe number.

The term "recipe," it should be added, does not always indicate consistency, as the quality of some recipes change from year-to-year, as do the contents of the cake. Perhaps only the factories producing the recipes really know what makes them consistent enough to label by these numbers.

Occasionally, a three digit code is attached to the recipe number by hyphenation. The first digit of this code represents the year the cake was produced, and the other two numbers indicate the production number within that year.Dead bluebottles were scattered on his hair and shoulders.
