An extra strong variation on the regular Vlo, for the 25th anniversary of De Bierkoning, a bottleshop in Amsterdam. Also dryhoppped with Centennial hops. Note: the bottles mention 7% ABV and not the word Extra but has an extra label that says "Extra Speciale Vlo, tgv 25 jaar de bierkoning. Koudgehopt 9% vol alc.".
