Gladfield Big O® Malted Oats

Gladfield Big O® Malted Oats are a premium alternative to rolled or flaked oats, offering enhanced flavour, improved lautering performance, and the smooth, silky mouthfeel brewers love. Fully modified and carefully kilned, Big O develops rich nutty and toasted oat flavours that add greater complexity than traditional flaked oat products.

Ideal for Stouts, Porters, New England (Hazy) IPAs, Oat Cream Ales, and other full-bodied beer styles, Big O delivers excellent body, haze stability, and improved mash performance.

Features

• Fully modified malted oats
• Rich nutty and toasted oat flavour
• Produces a smooth, silky mouthfeel
• Excellent for haze formation in Hazy IPAs
• Large husk improves mash filtration and sparging
• Suitable for all-grain brewing

Brewing Benefits

Unlike rolled or flaked oats, Big O retains a substantial husk, which helps improve wort run-off and reduces the risk of a stuck mash. The kilning process enhances the natural oat character, contributing greater depth of flavour while maintaining the creamy texture expected from oat-based beers.

Brewing Notes

• Use at up to 20% of the total grain bill.
• Big O absorbs more water than barley malt, so allow extra strike water when mashing.
• Mix thoroughly with your barley malt before milling to achieve an even crush and consistent mash performance.

Typical Usage: Up to 20% of the total grist.
