1st timer, go easy....

WWS I found that 2 years didnt do too much but I do have a 7 year old bottle which I have higher hopes for.
Expedition I only had 1 bottle and kept it for 3 years and have to say it was one of my top 5 cellared beers.
Ten Fidy I saw zero improvement or much change for that matter over 2, 3, and 4 years.
The other two I have some stashed away but have not had any with significant age.
For easier to acquire beers (depending on if you trade at all) to add, Great Divide Yeti, Troegs Flying Mouflan, Sierra Nevada Bigfoot, Dark Horse Plead the Fifth.

 

My experience with aging FIS more than a year has not been good. Just my opinion.

 

First make sure you try each one fresh
I would go Dogfish Immort Ale and Sierra Nevada Bigfoot

 

Pretty soon you'll be investing in bigger storage space and more expensive beers. Quit now while ahead. If I'm just "experimenting" with aging a beer then I only age 2-3 tops so if its a disappointment its not too much of a loss. To answer your question I've found that beers with the most change over any amount of time have been anything barrel aged (bourbon, brandy, oak, etc..), with coffee, and wild/sours. Barleywines are pretty good too, might just be my palate but normally I don't notice a large difference year to year.

Hope any of this helps, enjoy your new hobby

Drink the Burton Batons fresh and stash away some Palo Santo Marrons instead.

 

Burton turns into a nice barleywine after 1.5-2 years.

 

Im not criticizing but whats your reasoning behind having such a high count of each? You say you only have room for 12 more....so space is obv an issue. Then why cellar 12 founders imperial stout? Do you plan on trying one each for the next 12 years? I would cut that down first.

You seem to be into the imperial stouts...throw a speedway stout in there

 

Don't waste your limited space with 12 FIS, 4 seems like a much more reasonable total. Also, I don't think that you should monopolize your space with imperial stouts. Barleywines, scotch ales, old ales and Belgian quads are also styles that I've had some success with.

 

IPAs don't turn into barleywines. IPAs that are aged turn into aged IPAs. Barleywines that are aged turn into aged barleywines. Beers don't change styles....




....unless you keep them in a magic closet.

 

Get more Expedition. Drink the Ten Fidy. I've had it with one and two years on it, and it didn't really change. And sentiments to @csurowiec about the Palo Santo. That one ages very nicely!

 

Have you tasted a two year old Burton? I realize it doesn't "change the style" but it does happen to change the flavor. So I'm sorry, it has a barleywine FLAVOR after a couple years. Acceptable?

 

I'll accept it

Really what you're experiencing though, is the hops fading and the malt body being more forward. As you mentioned, that a common flavor profile of many barleywines. And yes, I have tried 1 and 2 year-old Burton side-by-side. I really didn't care for them with age, so that won't be something I experiment with again. In fact, the 2010 bottle that I opened at that time was nearly a gusher, had a very aggressive head, and tasted somewhat tart. I'd guess there was an infection issue with that one.
