The Potential of Rice Malt in Brewing Beer

Rice, a staple food for many, is now poised to take on a more significant role in an unexpected industry – beer brewing. Arkansas, a major producer of rice, is at the forefront of this emerging trend. Climate change and global conflicts have led to a shortage of traditional beer brewing ingredients like barley, prompting food scientists to explore alternative sources such as rice malt. A recent study published in the journal Beverages sheds light on the potential of malted rice to revolutionize the brewing process, particularly in the creation of gluten-free and all-malt beers with high adjunct inclusions.

The Science Behind Malted Rice

Malted rice, a novel ingredient in the brewing world, offers promising qualities for beer production. The process of malting involves germinating the rice grains, followed by drying and heating to halt germination. This process activates enzymes in the rice, enabling the conversion of starches into fermentable sugars during brewing. Unlike traditional brewing methods that utilize milled white rice as an adjunct, malted rice eliminates the need for additional processing steps, potentially streamlining the brewing process.

Lead author of the study, Bernardo P. Guimaraes, along with his adviser Scott Lafontaine, discovered that malted rice exhibits self-saccharifying properties, meaning it can efficiently convert starch into sugar without the need for external enzymes or supplements. The study evaluated 19 rice cultivars important to the U.S. rice industry, highlighting the malting potential of different varieties. Long-grain rice, in particular, demonstrated significant promise as a competitor to malted barley in terms of sugar content and brewing qualities.

Implications for the Brewing Industry

The findings of the study open up new avenues for brewers, offering a sustainable and locally-sourced alternative to traditional brewing grains. With the rising costs of barley and the impact of climate change on agricultural practices, malted rice emerges as a viable substitute for barley in beer production. The study also revealed that rice malt possesses higher protein levels than previously reported, suggesting potential applications as an alternative protein source in food products.

Moreover, the unique characteristics of malted rice, such as varying gelatinization temperatures and mashing parameters, present opportunities for brewers to experiment with different brewing techniques and flavors. The study’s focus on gluten-free rice varieties underscores the versatility of rice malt in catering to diverse consumer preferences and dietary restrictions.

Future Prospects and Considerations

As food scientists continue to explore the potential of rice malt in beer brewing, ongoing research aims to assess the economic feasibility and environmental impact of incorporating rice into brewing practices. Lafontaine’s collaboration with the Agricultural Economics and Agribusiness Department underscores the importance of considering various economic factors, such as the cost of barley and the carbon footprint of different grains.

In addition to its brewing applications, malted rice shows promise as a value-added product for farmers, especially those dealing with chalky rice, a common issue affecting rice quality. By repurposing chalky rice into malted rice, farmers can mitigate losses and enhance the value of their crop. As the brewing industry adapts to changing climate conditions and consumer preferences, rice malt stands out as a sustainable and innovative ingredient with the potential to reshape the beer landscape.

The study on malted rice represents a significant step towards diversifying beer brewing practices and addressing challenges in the industry. By harnessing the malting potential of rice, brewers can create unique and flavorful beers while promoting sustainable agricultural practices. As the beer market continues to evolve, rice malt may emerge as a game-changer, offering new possibilities for brewers and consumers alike.
