Here is some discussion on the Beist and the subsequent absence from the Ardbeg shop.http://www.whiskymag.com/forum/viewtopic.php?f=6&t=9571
From what I've heard, the distillery was just out of stock. No discontinuation yet.
You can always get really great tasting notes as well as other information on Ardbeg and other Islay distilleries from Spirit of Islay's site. Main page is http://www.spiritofislay.net
, and the forums are at http://www.spiritofislay.net/warehouse4/
. You can ask about the cask selection etc. for the Uigeadail over there.
As for years produced (bottled), this is what I have so far.

(700ml and 750ml) 2004 on backThe label was changed sometime during the summer of 2004, removing the date from the back. This also coincided with adding the Post Code on the front label, and replacing the "Traditional Strength" in gold on front with "Non-Chill Filtered" in gold.2nd half 2004

(700ml and 750ml) no date2006
(700ml and 750ml) no dateI haven't personally confirmed 2007 or 2008 bottles, but I'm sure they have been produced. The US stocks don't change as fast as the UK/Europe so we seem to get a year or older stock on most Ardbeg's.
Hope this helps a little...
