Is the thread still"alive"?! No choice but to dig out this old thread as I have some questions about DOM and Yomeishu.

1. Any expiry date for DOM? Tried to search online and most ppl comment there is no expiry date! Is it true? As I discovered one unopened DOM which bought over 20 years ago!

2. Read in Yomeishu website that sealed bottle can keep up to 4 years from manufacturing date. So if the bottle I have was manufactured in year Oct 2011, how do I calculate 4 years properly? Does it mean I can consume it before Oct 2015? Not Oct 2014?
