Somebody pulled your leg.
Chimay rests in the refermentation cellar for 3 weeks before being shipped out. Verifiable via their own website or read Brew Like a Monk.
Also from Chimay's FAQ:
* How and for how long can one keep Chimay Trappist beers?
Preferably in a vertical position so that the yeast remains at the bottom of the bottle, at a temperature of 10-12°C (50 to 53,6°F).
The consume by date given on some labels is a recommendation but does not mean that the beer cannot be drunk after that date. It can never, in fact, go "bad ".
Chimay Blue/Grand Reserve being vintage, some connoisseurs keep them for 10, 15 or 20 years. It will oxidise in the course of time.
The Red/Premier must be consumed more quickly and we recommend that you drink Triple/Cinq Cents as young as possible so that it retains a maximum of bitterness. The personal taste of the drinker will influence the storage time of our beers.
