Petrus Dubbel if you want richness and staying power,
Vecchia Orsa Belgian if you want something lighter to session.
Both are Belgian dubbels with identical bitterness, but that extra ABV point in Petrus makes a real difference—it tips toward dessert territory. Vecchia Orsa stays more nimble, letting you have a second without the commitment.

Tasting notes
Petrus Dubbel
Petrus Dubbel hits you with immediate caramel and dark fruit—raisins, plum skin, a whisper of cherry. The body is noticeably thick, almost syrupy in the best way, and those phenols from the yeast come through as subtle spice on the back end. It's the kind of beer that asks you to slow down and actually taste it.
Vecchia Orsa Belgian
Vecchia Orsa is lighter on its feet—you get the same dark fruit and caramel notes, but they're sketched in rather than painted thick. There's a dryness to it that the Petrus doesn't have, and it drinks almost crisp despite being a dubbel. The finish is cleaner, less lingering spice.
