Just to return to Penderyn, it's useful to note that the different barrels used to age the whisky really make a huge difference to the flavour. They found one year that they'd bought barrels from Laphroaig, and to their amazement found that the whisky aged in those tasted almost identical to Laphroaig. So if you try one style and it's not to your taste, don't assume that no Penderyn will be. A visit to their distillery is an interesting trip (it's just off the A465 Heads of the Valleys road, near Hirwaun) and one of the directors owns a pub in Hirwaun itself, which does some excellent food. They also make Merlyn (almost but not quite like Bailey's - much less sweet), Brecon gin and a good vodka, and they're linked to the Brains brewery group. And I'm not being paid to write any of this.
