Well, I know there many different views on this topic... but here is where I currently stand.
I don't put my beers in a secondary. Just a good primary under temprature control, and raise the temp a few degrees after primary fermentation is over to let the yeast clean up for an extra week. So typically, I am 2 weeks in the primary, then off to the keg or bottle. (After a cold crash & gelatin)
I prefer to age my beers in the keg/bottle. High ABV beers do seem to age very well and have subtle changes to flavor profile over time. (I have a bourbon barrel aged barleywine which is at 18 months and still getting better!) Be sure to minimize oxidation during bottling (and fill them properly .. very little air left on top).
When I use spices, I won't even sample them until 6 months in storage, and I find them very tasty even 12+ months out. Lots of the 'hard edges' the spices may add to the beer flavor tend to mellow out quite a bit, blend together as it were, with 6-12 months of aging. So, planning your 2012 Christmast brew now (with spices), is a great idea.
I think it will taste really great with only 8-10 months aging.
Hows that for a long answer to a short question?
