OiO Readiflakes® Flaked Corn (Maize) for Brewing

Mash-ready adjunct for a lighter body and crisp finish

OiO Readiflakes® Flaked Corn (also called flaked maize) is a classic brewing adjunct used to boost fermentability while keeping the finished beer smooth, light-bodied, and crisp. Because it’s pregelatinized, it can be added directly to the mash—making it an easy way to dial in a clean, highly drinkable profile in traditional and modern recipes.

Why Brewers Use Flaked Corn

  • Lighter body: Helps reduce heavy malt fullness for a smoother, more refreshing finish.
  • Crisp drinkability: Adds fermentables with a mild, clean character that won’t overpower the beer.
  • Mash-ready: Pregelatinized flakes are designed to be added straight to the mash.

How to Use It

  • Add to the mash: Mix with your crushed base malt and mash as normal.
  • Conversion note: Flaked corn relies on enzymes from malted grain (like 2-row or pilsner malt) for starch conversion.
  • No milling required: Use as-is.
  • Lautering tip: If you’re using a higher percentage of flakes, rice hulls can help maintain smooth runoff.

Suggested Usage

  • Typical range: 5% - 30% of the grist, depending on the style and desired dryness/body.
  • Great in styles like: Cream Ale, American Lager, Pre-Prohibition Lager, and other recipes where a clean, crisp profile is the goal.

Sizes We Offer

  • By the ounce: Perfect for recipe-sized additions and dialing in a specific percentage.
  • 50 lb bulk bag: Ideal for frequent brewers and high-volume brewing.

Storage

  • Keep cool and dry: Store sealed to maintain freshness and prevent moisture pickup.
  • Bulk bag tip: After opening, transfer to airtight containers for best long-term storage.

Frequently Asked Questions

Do you offer grain milling services?

Yes, we provide grain milling services free of charge before shipping. To have your grain milled, please select the "Yes, please mill my grain" option on each grain product before adding it to your cart. We use a high-end, 3-roller mill from Spike, set to a standard gap of 4.5, which achieves optimal cracking while minimizing excessive flour. If you prefer a coarser or finer mill, leave a note in the shopping cart, and we’ll adjust it to your preference.

If we notice that most grains were selected for milling but a few were not, we will assume it was an oversight and mill all of them. If your intention is different, please clarify in the shopping cart notes section.

How do you ensure accuracy when weighing grains?

We take great care to ensure that you receive the correct grains in the exact quantities needed for your recipe. Our multi-step process ensures precision, starting with weighing each grain type individually to an accuracy of 0.08 ounces. After that, we perform a final check by weighing the combined total to confirm accuracy. Your total grain weight will always be slightly over the ordered amount, never under, and always within an acceptable range for even the most detail-oriented brewers (like ourselves).

How are grains packaged before shipment?

We provide a convenient recipe-building tool to streamline the process for you, our team, and the environment. We encourage you to use this tool to build your recipes, ensuring you get exactly what you’ve ordered in the correct quantities. By combining all the grains for a single recipe into one bag, we help speed up your brew day, reduce packaging waste, and save time during order fulfillment. Rest assured, we prioritize accuracy when measuring and packing your grains.
