Well, the thing is, Chimay has changed their website. At first they had the year and botteling month on their website. Within the same year, they had different entries, of whom I copy pasted the different barrel %'s. Now they dropped all the different versions into one main category per year. So, for the new releases, we will put them in one entry per year, as it is now being presented by the brewery. But we leave the old ones. I’ll add precise bottle dates, if that’s any help?
The batch numbers are total bollocks as they can nowhere be found online. Maybe webshops get them as they order with Chimay or their own supplier, but us, consumers, cannot detect batch number when we hold a bottle.
