those of you (willie...) who have heard my poitin rant before, read no further... Unfortunately, the majority of legal "poitins/potcheens" out there arent either traditional poitin or even unaged whiskey at all but, essentially, neutral grain spirits (ie vodkas) with a funny name and usually a healthy wallop of paddywhackery on the label. In fact, there's very little cohesion as to what this new category is supposed to be other than one more white spirit with a fake history. Poitin, right down to the name itself (i.e. little pot) is unaged pot still product (i guarantee you no farmer in the history of booze was using a column still.) The glendalough stuff is almost certainly column still vodka (albeit an interesting vodka with a bit of beet thrown in), bunratty and knockeen hills are an insult to the word and, as much as i like the teeling stuff, even thats not technically "poitin" in any historically defensible sense (it's essentially an unaged blend, i.e. with a column still component) but at least we're in the realm of whiskey here. I agree with Willie that the most delicious stuff by a long mile was the Cooley poitín (may it rest in peace) and whoever told willie that it tastes like the real thing has told me much the same thing...
whether or not commercial poitin tries to resemble trad poitin (you know, they could always throw in some copper sulphate and alll the less savoury aspects of illicit distilling), it'd be incredible to see the term emerge as a descriptor for newmake whiskey. In the states the term "white dog" has been used for ages to describe essentially that and many emerging microdistilleries are doing a great trade in those.
