Last week I did the brewery tour with a friend. During the tour we were told two things that we found interesting...
1. Light is bad for beer and green bottles are bad (duh). They admit this but say that the marketing department wants green.
2. Bottles and cans are pasteurized but kegs are not.
After the tour it was time to drink samples from the bar. We asked for a bottle of the lager to compare with the draught lager. WOW! Even an untrained nose would have no problem picking up the skunk from the bottle. We pointed it out to the nice lady who gave the tour and she could instantly tell the difference.
It is quite sad that the bottles are skunked before ever leaving the brewery grounds...and that 'marketing' is cool with it.
