What is a Mash Tun/Lauter Tun Combination?
Mash tun/Lauter tun combinations combine all the functionality of a mash tun and a lauter tun, both key components in a brewhouse, into a single tank component where all brewing processes take place.
A mash tun/lauter tun combo combines all the functionality of a mash tun and lauter tun in one tank:
- Grain, previously cracked in the grain mill, is combined with metered hot water
- Complex starches are converted into fermentable simple sugars
- Wort is recirculated over a grain bed in a clarifying process called vorlauf
- Sugars are rinsed and extracted from the grain during the sparge cycle
- Wetted grain is separated from liquid wort using a false bottom filter screen before transfer to the brew kettle
Combining the mash tun and lauter tun functionality into a single tank unit increases your efficiency and reduces your brewing equipment costs
