Cooley Distilleries in the Republic of Ireland makes 8, 15 and 18 yr old Greenore Maize Single Grain Whiskeys. Currently no other 'Single Grain' products are produced by Cooley other than the maize version. Cooley posts a few highly questionable comments about the nature and uses of 'Grain Whiskeys' on its site while describing the Greenore Whiskeys. This language will have to be rethought if they ever want "Single Grain" to mean something other than Maize, and to put out either a wheat or a rye 'single grain' whiskey-- since wheat and rye are both much more flavourful than barley-malt
Nose: a very nice bouquet of mostly wood flavours, featuring caramel, vanilla, honey, a touch of rosewater, and a trace of grain
Taste: there is definitely a nice subtle underlying maize flavour here, but as with younger aged corn whiskeys, like Mellow Corn, the wood flavours are much more powerful than tasting the grain. There is a lot of vanilla, caramel, and toffee. There is a touch of oatmeal flavour in the profile as well
Finish: rather long, with sweet caramel the dominant flavour. The finish is not as enjoyable as the delivery
Balance: This is a pleasant whiskey, but like younger aged Corn whiskeys, it is an adventure in wood, not an adventure in grain. I am now convinced that either a very well made unaged corn whiskey or one that is aged no more than maybe one year, would be the best way to taste the grain known as maize=corn. I expect that in the near future some artisan distilleries, probably in the US, will give me the really clear taste of corn for which I have been looking
I am very fond of this Greenore. I always have a bottle in my cabinet (apart from the closed bottles - I have the whole range - which I collect). It is the only Irish single grain on the market, if I'm not mistaken. And a very good one. The brand was recently sold to Jim Beam Inc, but the people at Cooley have promised they will keep producing this wonderful spirit.
