How fossils help make beer!

The production of beer is a complex process that requires a wide variety of organic materials in order to brew it. Some of the more commonly known ingredients include yeast and hops, but the most uncommon ingredient is that of diatomite-- fossilized algae!



Diatomite is a sedimentary rock that is the fossilized remains of diatoms, which are microscopic, single-celled algae that live in marine or fresh water. They produce hard parts made of silicon dioxide, and when fossilized they create a sedimentary rock. Diatomite is most often used in construction as a filler and absorbent, which is due to the thin and exposed layers of the diatoms skeletal remains. This is where diatomite comes into play of beer production! Due to its structure and porosity, diatomite acts as a soft absorbent filter for beer to run through.


When using diatomite as a filter, it is important to use sediment from a freshwater environment versus a marine water environment. This ensures that the beer has the cleanest and freshest taste possible!
