Double Double Barrel Ale by Fire Stone Walker is a 12% ABV Imperial Special Bitter Barley Wine. It is twice the strength in terms of flavor and alcohol as the original DBA. The DBA is aged for about 10 months in real oak barrels with British yeast. This beer reminds me so much of rich toffee found in many barrel aged beers. However it is a dulce de leche type. Flavors range from dulce de leche caramel, vanilla, honey, maple, toasty coconut, toffee, almonds, oak, bourbon, apples, raisins, plums and toasted bread. It is more sweet than bitter really. The flavors and levels of masking and balances are good here. It is not as strong as the Barrel Aged Blockhead, but it is similar in flavor although this has other flavors not found in that beer. It has some minor quad aspects to it so that is why I like this as well. Barley wine and barrel aged beer lovers find this one and give it a try. It is a damn good and delicious beer 😛
