Liquid Malt Extract (Lme) is concentrated, unfermented brewery wort, a viscous syrup used in brewing. To produce Malt Extract, water is heated and the grains to be used are milled. The milled grains are added to the heated water and left for a period of time. This produces a sweet ‘wort’ which is filtered to remove the spent grains. The wort is then evaporated to remove 80% of the water, leaving thick, sticky LME.
