Any idea what it "really" is in the bottle?
Google gets a few hits similar to this one:

"After a bit of searching in google I found out that Ben Bracken is indeed a 12 year old Speyside malt, called Tamnavulin. Tamnavulin distillery closed down about 5 years ago and Whyte & Mackay Ltd the former owners of Tamnavulin sold a load of casks of Tamnavulin to Lidl supermarket and they now sell it under the name Ben Bracken"
Logically, there should be another 7 years production available if Lidl have exclusive rights to the remaining stock.
