Review by Nonjatta contributor - Dramtastic:
"Mars Single Cask # 904 Aged 15 Years. 43 per cent alcohol.
Nose: Fairly light, with apricot, walnuts, fresh cut timber, sandalwood, caramels and lime.
Palate: Peanuts, walnuts, wood chips, wood spice, caramels, lime, cinnamon and coconut
Finish: Shortish with nuts mixed with Werther`s originals and lime.
General comment: There are some nice flavours there but you have to dig hard to find them.
