i brewed the NB townhall1800 AG a couple years back. hated the first case i drank in the first year after bottling, then, on a lark, i opened a bottle about 13 months after bottling: stunning! the very aggressive hop bittness had mellowed considerably, the beer was perfectly balanced. i am planning to brew it again and INTEND to store it a year or more before opening. have faith in this beer, wouldn't want to touch the recipe, maybe just swap out yeasts to try different things.
