There is no fermentation involved! Only the action of the natural enzymes in the tea leaves.
Enzyme -
Any of numerous proteins produced in living cells that accelerate or catalyze the metabolic processes of an organism. Enzymes are usually very selective in the molecules that they act upon, called substrates, often reacting with only a single substrate. The substrate binds to the enzyme at a location called the active site just before the reaction catalyzed by the enzyme takes place. Enzymes can speed up chemical reactions by up to a millionfold, but only function within a narrow temperature and pH range, outside of which they can lose their structure and become denatured. Enzymes are involved in such processes as the breaking down of the large protein, starch, and fat molecules in food into smaller molecules during digestion, the joining together of nucleotides into strands of DNA, and the addition of a phosphate group to ADP to form ATP. The names of enzymes usually end in the suffix -ase.
Fermentation -
The process by which complex organic compounds, such as glucose, are broken down by the action of enzymes into simpler compounds without the use of oxygen. Fermentation results in the production of energy in the form of two ATP molecules, and produces less energy than the aerobic process of cellular respiration. The other end products of fermentation differ depending on the organism. In many bacteria, fungi, protists, and animals cells (notably muscle cells in the body), fermentation produces lactic acid and lactate, carbon dioxide, and water. In yeast and most plant cells, fermentation produces ethyl alcohol, carbon dioxide, and water.
By examining the two definitions the key difference is the presence of oxygen, thus no alcohol is produced.
The RAzEr needs to repent!
He has passed on a "false witness" to the saints, although unknowingly. He needs to make amends and reparations.

While in college I studied a course on alcoholism. There was a list of alcoholic beverages. Tea was on the list. It seems there is a fermentation process in order to get the tea leaves where they need to be in order to have proper tea. I had to let a few people who were 'total abstainers" and also
