Yes, I know this is cheating; every fatty cheese goes well with a saison. The classic Saison Dupont would be too dry and floral hoppy with this milder blue combination. So I picked the Category 12 Unsanctioned Saison. I wouldn't call the C12 a saison, it is too malty. I think the Unsanctioned is closer to the French style saison called biere de garde. The saison style is more familiar to beer drinkers than biere de garde.
This combination was beer and cheese heaven. The carbonation of the C12 lifted the fatty cheese off the tongue to reveal a citric, fruity tartness. There was enough fruitiness in the C12 to draw out the lemon citrus of the Mascarpone. Malty sweetness balanced out the bitter and tartness of the blue Gorgonzola.
New week I shall try and find the idea cheese pairing with a Victoria classic: Lighthouse Keepers Stout.
