Quad Fundum from Opener Bier is a Dongen-brewed Quadrupel built for contemplation, not quick consumption. This soft-spoken beer layers sweet malt, spice and fruit character alongside coffee and cocoa notes. At 10% ABV, the alcohol warms gently without overpowering the composition.

Taste reveals balance between richness and approachability. Wine-like undertones and subtle spice—reminiscent of speculaas—weave through the palate, supported by layered fruit esters. The mouthfeel is pleasant, with light prickling on the tongue and a lingering finish that invites another sip.
