Mikkeller and To present to you - our effort to make the lightest beer in the world. What is the lightest beer in the world??? What we mean, is that Walk On Water is the beer with the lowest density. After working on the breakdown of residual sweetness (dextrines etc.) and optimising our fermentation, we ended up with this beast of a boozy beer! 14% alcohol and no residual sugar making it a 100% attenuation fermented beer makes this the dryest and lightest beer in the world.
