Old Peculier is a prime example of an old ale. Here is the
description from Beeradvocate.

Old Ales, also referred to in the past as Stock Ales, are low attenuated beers with high levels of dextrins, creating a full malt body with plenty of character. Old Ales from centuries past were often transferred into vats to mature, hence the name. Commonly a rich, dark amber to a deep brown color, some examples are nearly black. Tamed aromatics. Although bittering levels can greatly vary, expect fruity, vinous, intense malt flavors and sharp alcohol characteristics. The often racy but mellow attitude of the beer may also include acidic notes, raisins, and black currants.

Brewer's Notes

THE LEGEND! Old Peculier is possibly one of the country’s most well-known and loved ales. This unique, beautiful brew is often imitated but never matched and is sold literally all over the world. With countless awards to its credit, it is something of which every Briton can be very proud and is the epitome of the greatest of British brewing tradition. The name pays tribute to the unique ecclesiastical status of Masham as a ‘Court of the Peculier’ and is also a reference to the strong characteristic of the beer! For many years it was affectionately referred to as Yorkshire’s ‘Lunatic’s Broth’.

Old Peculier is a beautiful, yet very simple beer, brewed using a very generous blend of finest pale, crystal, and roasted barley with two bitter hops combined with the majestic and noble Fuggle’ hop to produce a beer of awesome full-bodied flavour with subtle cherry and rich fruit overtones.

Tasting Notes

BBE = 31082005. I guess the beer is near its expiry and has aged at least six mouths. I think the beer has improved with age. I don't remember liking earlier cans for the 4-pack as well. 

The notes from Beeradvocate and the brewer are on the spot. A subdued beer with some sweetness and fruitiness. The brewer says that the aroma is subtle cherry and banana and that the taste is rich and fruity.
