What is Malt Extract? A Home Brewer's Guide to Malt Extract and Spray Malt
Share
What is malt extract and what does it do in home brewing?
Malt extract is concentrated fermentable sugar derived from malted barley — available as liquid (LME) or dried (DME/spray malt). It's the base ingredient in most beer kits, but it can also be used to boost kit beers, improve body and head retention, and add genuine malt character to your finished brew. Replacing plain sugar with malt extract is the single most effective upgrade for any kit beer. See our Brew Enhancer vs Sugar guide for a full comparison.
What is the difference between liquid malt extract and dried malt extract?
Liquid malt extract (LME) is a thick syrup that dissolves easily in hot water. Dried malt extract (DME), also called spray malt, is a fine powder with a longer shelf life and slightly higher fermentable content per gram. Both produce the same result — the choice comes down to convenience. Spray malt is easier to store and measure; liquid is faster to dissolve. Browse our full spray malt range.
How do you use malt extract to improve a beer kit?
Replace the 1kg of plain sugar your kit calls for with spray malt or a Brew Enhancer. This adds genuine malt flavour, improved body, and better head retention — a very noticeable improvement for minimal extra cost. Use pale spray malt for lighter beers, medium for bitters, and dark for stouts and porters. For a complete breakdown, read our Brew Enhancer guide.
What is spray malt and how is it different from malt extract?
Spray malt is dried malt extract in powder form — functionally the same product, just with the water removed. It's available in Light, Medium, Dark, and Wheat varieties at BrewCo UK, each adding different colour and flavour. It's particularly useful as a kit enhancer and for all-grain or extract brewers building their own recipes. Browse our full range of malt extracts and spray malts at BrewCo UK.
