Recently, the antioxidant properties of teas have attracted attention, and tea drinks have become a representative of sugar-free drinks as healthy drinks. However, as a drawback of the conventional tea beverage, there is a problem that the fragrance of the freshness of tea originally possessed is lost before it reaches the consumer. As a means for solving this problem, a method of passing steam through tea leaves in a short time (Japanese Patent Application Laid-Open No. Hei 8-116882) to obtain a fresh fragrance of tea, distills fragrance components from tea in the presence of an antioxidant. Method (JP-A-8-73)
886) has been proposed. However, the aroma obtained by the above method also deteriorated with time, and did not solve the problem.

From the idea that the aroma of tea is due to the decomposition of carotene present in tea leaves, a method of adding a thermally decomposed product of carotene to a tea beverage has been proposed (Japanese Patent Publication No. 7-99995). It was mainly floral incense, not the original scent of tea.

て用いられる。[0006] The 4-methoxy-2-methyl-2-butanethiol used in the present invention is a component found in blackcurrants, but no component has been reported as a tea component yet, much less tea. It has never been studied for beverages. 4-methoxy-2-methyl-2-
Butanethiol can be obtained from the above natural product by means of extraction, precision distillation under reduced pressure, column chromatography, liquid chromatography, or the like, or can be obtained by synthetic means. 4-odor-methoxy-2-methyl-2-butanethiol is extremely strong, the threshold in aqueous solution is a 0.03～0.06Ppb, but is intended to feel the unpleasant smell even in trace amounts, 10-5 2 ppb, more preferably 10 -4 to 10 ppb, still more preferably 10 -3 to 1 pp
Only when it is contained in the tea beverage in the range of b, a tea beverage having a light and mild green aroma of the freshly prepared tea can be obtained. If less than 10 -5 ppb content, other can not be obtained lightly mild green aroma with even put fresh tea with a synergistic effect with any components, content 10 2 p
If it exceeds pb, it has an unpleasant odor and is not suitable for beverages. Therefore, when 4-methoxy-2-methyl-2-butanethiol is added to a flavor composition, when 1% of the flavor is added to a tea beverage, 10 -3 to 10 4 ppb, and more. It is preferably 10 -2 to 10 3 ppb, more preferably 1 to 10 ppb.
0 -1 10 must be added in an amount of 2 ppb. Since 4-methoxy-2-methyl-2-butanethiol is used in a very small amount, it is preferably dissolved in a solvent such as ethanol or propylene glycol and added to a tea beverage as it is, or a flavor composition for a tea beverage. It is used by adding it to a product.
