Als Blindsample verkostet. Bei der Auflösung war ich schon überrascht, dass da ein Rum aus Guyana im Glas war. Hat mir sehr gut gefallen. Überrascht war ich ebenfalls, dass es sich um ein Projekt aus Deutschland gehandelt hat.

7.8/10

Ein neues kleines Projekt aus Deutschland. Erstmal positiv zu bemerken: Sehr transparent und anschaulich. Alle Infos auf dem Label (das ich recht schicke) und dazu schön aufgearbeitet, statt bloßer Angabe. Zum Stoff an sich: Trotz Fassstärke (diese Abfüllung gibt es auch in Trinkstärke) und recht jungem Alter sehr weich, der Alkohol ist gut integriert. Der Grund-Rum an sich war wohl sehr nichtssagend, denn trotz zweier Fässer inklusive Bockbier-Vorbelegung haben wir hier einen erstaunlich zurückhaltenden Rum! In der Nase fast nichtssagend, ist der Gaumen sehr angenehm. Mit einem weichen, spanischen Rum-Charakter (obwohl aus Guyana!) und einem anschließenden sanften Biereinschlag. Letzteres ist für mich bemerkenswert: Ich bin beileibe kein Fan von Finishes und alles Richtung Bier fand ich in der Vergangenheit eher schwierig. Der Mercator liefert das Finish aber, wie es sein sollte: Dezent, gut in den Gesamteindruck integriert und nicht überlagernd. Zu Beginn fast nicht wahrnehmbar, entwickelt sich auf der Zunge ein angenehm maltier Geschmack, der langsam in einen hopfig-fruchtigen Abgang übergeht. Für eine höhere Bewertung fehlt mir etwas Intensität und Geschmack aber dennoch für mich ein gelungener Einstand des Mercator-Rums!
