you could pay a visit to www.thewhiskystore.de
and go to Shop. In the shop you can find section "Stills, Water Jugs, Accessories". There are barbooster from Ardbeg, Bushmills etc. but if I looked correctly for instance Bowmore barbooster did not have any bottle statements on the plates, only Bowmore label was visible. Others seemed to have plate marked places for particular bottles.
P.S. There was also that special Classic Malt barbooster, if you really like to have that one where are places for Lagavulin 16Y, Dalwhinnie 15Y, Talisker 10Y, Oban 14Y, Cragganmore 12Y, Glenkinchie 10Y.
