+1 Its all hard to say, best way is to try it and see, although I would prefer to oak a porter rather than an IPA, oaked IPA's just sound wrong to me but I've only tried the one (a brewpub's not mine) and it was was overdone
I agree with the IPA comment, it seems like people are often just oaking for the sake of oaking (and other things, as well), to add additional flavor/complexity but ignoring the idea that less is often more. Even when oaking could work, this all holds true, and it's generally overdone. But I've never had an oaked IPA that I felt the oak flavor blended well with the beer, nor have I ever had an oak IPA and thought, "this would go better with oak."
I should add though, that despite all the "less is more"/anti-oak talk, my most recent beer is a tropical stout that will be somewhat oaked. I also agree with the idea that it works best with porter, and was initially going to do that, but tropical stout isn't all that different anyways, and I felt it better fit the circumstances. I got myself a used 5gal oak barrel recently, sourced from a rum distillery and still rum-soaked (and even containing a little bit I could pour out and drink.) I got it specifically used, because I want to use it for Flanders Reds, and while those really ought to be fermented in barrels, you don't want the barrel to actually contribute flavor (ie. you want to use a "neutral" barrel.) But first I need to extract the rest of the oak flavor from it, and since it's not every day I have a rum-soaked oak barrel to use, I figured I might as well take advantage of it, even though there are many other beers ranking higher on my "must brew" list.
So I did some head-scratching trying to figure out the best way to complement the rum flavors I'll get (whiskey is much easier IMO), and figured a tropical stout was also perfect. And just to make me *really* look like a hypocrite with this "less is more" stuff, I'm also adding a couple pounds of toasted coconut to the whole thing, so that eventually, the currently-fermenting tropical stout will be a coconut rum-barrel tropical stout.
We'll see how it turns out, but one thing I'll definitely be doing is daily tastings in order to make sure the oak isn't overpowering. Nothing worse than these beers that make me feel like I'm somehow drinking a tree.
