ABSTRACT OF THE INVENTION The present invention relates to a method of monitoring the quantity of extract from mash in a brewing process. A mash, typically made up of ground malt and water is introduced in a lauter tun having, typically, a first, central core zone, a second zone surrounding the first zone and a third zone surrounding the second zone, around the periphery of the lauter tun, there being extraction pipes for extracting wort from each of the zones in said lauter tun. Saccharified wort is extracted from the lauter tun, via the extraction pipes from the zones, the pipes leading to a wort kettle, and sparge water is added to the lauter tun as wort is extracted to extract further solids from the ground malt in the mash. The extractable solids in the extraction pipe from each said zone are monitored by sequentially passing samples of wort from each pipe through a densimeter. Then, the flow of wort from the extraction pipe from each said zone is adjusted by automatic flow adjustment means to obtain a flow of wort in each extraction pipe having approximately the same extractable solids.
