Liquid malt extract is often used to make beer at home. Some home brewers use it instead of plain corn sugar (dextrose) to add fermentables to their wort. Other home brewers use the liquid malt extract (LME) to grow yeast cultures.
This is a 1.3kg container of Liquid Malt Extract. It has the consistency of molasses, and is equivalent in fermentables to 1kg of fermentation sugar (dextrose). The remaining 0.3kg is water, and unfermentable solids.
