For years the controversy may have been fermenting in the college of presbyters at Alexandria.
The liberated energy takes the form of heat, which raises the temperature of the fermenting wort.
This access is especially desirable as regards the store-yards and framing ground, where fermenting manures and tree leaves for making up hot beds, coals or wood for fuel and ingredients for composts, together with flower-pots and the many necessaries of garden culture, have to be accommodated.
Should the leaf be intended to be cured as green tea, the fermenting process is omitted and some other processes applied, but in India very little green tea is manufactured.
The principal difference from the manner described of making black tea lies in the omission of the withering and fermenting, and the substitution for those of a steaming or panning process.
