Holzknacker Limited Edition IV is an ambitious barleywine from Vienna's Brew Age brewery, weighing in at 12.5% ABV. It is part of their Holzknacker series, in which their base strong ale—the Nussknacker—is refined through maturation in wooden casks previously used for spirits. Limited Edition IV belongs to this specialized range, where Brew Age combines their expertise in strong ales with secondary wood aging.

This is a beer for those who appreciate complexity and maturity. The combination of high alcohol content, malty depth, and wood-cask influence creates a contemplative beer with many layers.
