If no age is given on the bottle, it is 3 years. The oldest I've had was 10 years. The older the better.
The number may be in Arabic numerals or Chinese characters, the most common being:
3 year old - 三年陈
6 year old - 六年陈
8 year old - 八年陈
10 year old - 十年陈
I appreciate all the information you've presented. It does, indeed, look like I grabbed a decent, if not great, bottle of vinegar from the shelf. It should work fine for its intended purpose. Certainly a good starting point for future explorations.
