BrauKon spice extraction system
In addition to hops, other natural, aromatic ingredients such as spices or herbs can also be used for brewing. For example, Belgian witbier (wheat beer) is traditionally brewed with coriander and orange peel. The ingredients for such beers are often packed in bags, similar to a large tea bag, and hung in the wort. However, this approach is not optimal, since the ingredients inside the bag often remain dry and are not uniformly leached. This results in significant yield losses.
