In their other peated expressions David mentioned that they aimed for the Highland style/source of peated barley vs typical Islay/Island style. Also the ppm are around the 20 mark vs your usual ~ double for most of the main islay distilleries. The aim was to ensure balance and not over power the other components of the whiskies. All David's whiskey were very well balanced which is important for the type of speyside profile dram and shows true craftsmanship. Anyhow 8 years ago he was offered a load of peated Belgian malt. He said he got offers all the time so didn't think much of it but when he sampled it he knew he had something special on his hands so bought a few pallet loads. 8 years later this was the result. Apparently we'd need to wait for another 8 years if he's going to do it again. Anyhow the dram itself is really nice. The malty vanilla balancing out with the islay style peat profile. Very nice and my favorite of the range. Sadly not in my tasting pack I bought as this just landed 5 weeks ago. They had a naming competition and out of several hundred entries his son wittled them down to a select few and there were two names they were in agreement on so they used both on the label. Sovereign Smoke and Defiantly Peated.
