Looking through my collection this weekend I noticed most of my bottlings are OB's in fact besides for the a few of the RM series and some Dewer Rattray stuff and some odd ones I have very few IB's. I have many different expressions of single distillerys for example 7 different Balvenie's and 5 Laphroaigs 6 Glenlivet's 6 Glenmo's etc. etc.
Good query Woodhill: I tend to purchase OB's in general as I find that the distillery offering is a fairly good presentation of what they can do.
I pick up the odd IB when it is a bit unusual or when I happen upon it and have some spare cash in my jeans. Usually when there's nothing else in the shop that I don't already own or have tried in the OB lines.
The nice thing about IBs is they will tend to select an age that the distillery doesn't offer. It's obviously a good marketing strategy for them, but also I like the fact that I can taste something in a different year and see where an older OB has come from or where a younger one is going. Especially if I have an OB to do a head to head with.
And finally, it is more likely that I will see an OB in my market than an IB. Signatory makes it over here most often and the large share of my IBs are theirs'.
I have come to enjoy young Islays very much, in the 6-9 year range, and love the cask strenght offering of the IBs. That said, I have more OBs than IBs, by two to one. The IBs I have around tend to be somewhat hard to find (or expensive) in OBs, Brora, Port Ellen, Linlithgow, ect.
OB for me very much for the same reasons as the guys above. Also I like to have the packing of the distillery which marks the bottle out as different from others. Where as an IB bottler will have its look irrespective of whats inside the bottle. Which in itself is not a bad thing. But it differentiates the bottler rather than the distillery.
I do have a few IB's but in proportion to the rest of my collection its under 5%. I quite like for drinking the G & M Private Collection series.
Mainly OB's. I think it looks and feels a lot better if you have the bottles lined up nicely by distillery, clearly showing similar expressions... A lineup of IB's can consist of a single bottler, covering most popular distilleries. This doesn't appeal to me from a drinking collector's point of view...
