Maize Malt

Maize is also known as Corn.

Gladfield has stepped up a notch in innovation and arguability we are the first commercial maltings to malt maize in a commercial scale.

Our Malted Maize is made from New Zealand grew field corn. Maize Malt allows brewers and distillers to use it directly in the mash, without an additional gelatinisation step. A great malt to use to produce American Light lagers and pilsners to add fermentables with little colour and a unique flavour. It can also be used as the base for a corn whiskey (bourbon).

Maize malt adds mild, less malty flavour to beers and less body. It also provides a drier and crisper beer. Maize Malt should be crushed along with other malts. No need to adjust the mill, cook it, step mash or mill it separately. We recommend adding Rice or Oat Hulls to recipes using more than 10% of Maize Malt to avoid a stuck mash.

To get the most out of the maize malt be sure to keep the grist percentage at under 30% as the corn will lack the same enzyme potential as barley.

We recommend milling the Maize malt along with the other malts. If that is not an option, you can pre-crush the maize malt with a rubber hammer while inside the bag. It will half the grains allowing it to go through the mill.

Check on your mill rollers to see if the knurling is not worn out, maybe you need to replace the rollers. The optimum mill gap is 1.45 mm.

Rate: up to 25% in beers and 51% in Bourbon Whiskey making
