Zeker & Vast is a barleywine from Brouwerij De Molen in Bodegraven, a Dutch craft brewery established in 2004 with a reputation for inventive and characterful beers. At 10.3% ABV, this is a full-bodied, rich beer designed for contemplative sipping.

The name plays on the contrast between certainty and flux—fitting for a beer that delivers complexity and depth. De Molen has built its identity partly on barrel-aging practices, maturing many of their beers on wooden vessels that add distinctive character to the final product.
