The Winter Warmer style is pretty nonspecific, in general it's any kind of ale, often a brown or red ale brewed with "winter" spices such as nutmeg and cinnamon. "Imperial", which derived from the Imperial Russian Stout style https://ill-gottenbooty.blogspot.com/2017/09/beer-styles-barleywines-and-imperials.html has come to mean either extra high hop content, (IBUs) or extra high alcohol content (ABV).
Super Jubel comes across to me like a barleywine. It pours a dark brown with ruby highlights and a thin tan head. The ABV clocks in as 10.4% and imparts a boozy quality similar to red wine. There's a crazy amount of complexity, with favors falling all over themselves for dominance. Raisin and gingerbread lead the pack; oak and raspberry follow closely behind; there's also some orange peel and maraschino cherry, with figs and dates bringing up the rear along with cinnamon, nutmeg and allspice.
