Cellar Notes - Bottling Date Resource (Updated for Oud Beersel)

I find the whole aged beer / cellaring thing quite fascinating. Unfortunately, and unlike wine, determining bottling dates for many beers can be a difficult task. Below I've pulled together a few bottling date conventions:

Note that all data with respect to the trappist beers has been sourced from Danny Van Tricht at http://users.pandora.be/dvt/trappist2007/html/chimaybierene.htm (great job BTW).

Chimay
Dore: 4 years from best before ('BB') date
Blue: as per vintage year
Red: 4 years from BB year
White: 3 years from BB year

St Bernadus (our educated guess - happy to hear confirmations)
Triple: 3 years from BB date
Pater: 3 years from BB date
Prior: 5 years from BB date
Abt: 5 years from BB date

La Trappe
Blond: 2.5 years from BB date
Dubbel: 2.5 years from BB date
Tripel: 2.5 years from BB date
Quadrupel: 3 years from BB date

Orval
As per label bottling date

Oud Beersel
20 years from BB date

Rochefort
6: 5 years from BB date
8: 5 years from BB date
10: 5 years from BB date

Westmalle
Dubbel: 2 years from BB date
Tripel: 2 years from BB date

Gouden Carolas
Classic: 3 years from BB date

Unibroue - See below (unless vintage dated on bottle)
It's easy to translate the bottling date from the code printed on the bottle. For example, 'C08071726Q' translates to:

C = month (ie March)

0807 = day & year (ie 8th March 2007)

1726 = time (ie 5.26pm)

Q = location (ie Quebec)

If anybody has bottling date 'rules' or conventions for any other beers I'd love to get hold of them.
