Cereals - a guide to Flakes

To brew a beer, you need grain. Usually, this will be a malted variety, to ensure a certain amount of fermentable sugars. More and more brewers however add a percentage of unmalted grain. One of the easiest options is the use of flaked grains, also known as cereals.
To create cereals, the grain is steam-cooked and flattened between hot cylinders. Finally, the flaked grain is dried. The combination of heat and pressure pre-gelatinizes the starch. 
You can use flaked grains – like barley, oat, or wheat – for a multitude of reasons. These cereals serve to enhance specific characteristics, introduce unique aromas, influence color and clarity, and increase the number of fermentable sugars in the beer. 
Flakes-Maize

Flaked Maize

Brewing with corn is best done by adding flakes. It has little protein and can be added directly to your mash.
Result: Milder taste with a dry, crispy finish.
Flavour: Sweet, less malty.
Usage: Light Pilsners.
Flakes-Barley

Flaked Barley

These cereals will increase the volume of fermentable sugars, without adding body or taste. Some haziness might occur.
Result: Stronger head retention, smoother flavour.
Flavour: Slightly grainy.
Usage: Stouts.
Flakes-Oat

Flaked Oat

The excess in glucans results in haziness. It could also affect filtration, so you might want to add rice hulls to your brew.
Result: Additional body, head retention, haziness.
Flavour: Silky mouthfeel.
Usage: Oatmeal Stout, Porter, Witbier, New England IPA.
Flakes-Wheat

Flaked Wheat

This cereal imparts more intense flavours than the malted wheat. Flaked wheat ensures a hazy beer.
Result: Increased body and head retention.
Flavour: Spicy, bready.
Usage: Witbier, Weizen, New England IPA.
