Alberta Premium 30 Year Old Limited Edition® This is super whisky that just keeps getting better because by age 30, the palate simply explodes with flavours. That said, the 30 year old is, surprisingly, no more oaky than the 25. Neither is it as sweet or as fruity. Although both are rich in cedar and spices, the 30 year old is hotter, cleaner and lingers even longer. It also exhibits a pitchiness just hinted at in the 25.
