Adelphi didn’t/couldn’t call this Burnside [typically the recognised moniker for teaspooned Balvenie], because Cadenhead own that brand name. WF touched on this recently.
N: Besides the decidedly firm ex-PX influence, the distillate is detectable.
T: Very sherried on the palate with an oloroso-like spirit burn.
F: Sweet sulphur.
C: Too cask-led for my liking, but I attempt to regard it objectively.
