Sampled this last night at the Vic. Wow, big flavour! I loved the orange zest and coriander flavours. And I agree, while these were definitely discernable, they did not obliterate other flavours in the beer. In fact, for me I found a teasing of nutmeg somehow as well.
I think it's marvellous how beers like this one are developed and nurtured each year and take on subtle new characteristics. Makes life very interesting for us beer drinkers.
