Malt serves as a cornerstone ingredient in the brewing process, influencing the flavor, color, and body of the final product. Consequently, the proper handling and storage of malt are paramount to ensuring the quality and consistency of brewed beverages. In this guide, we outline best practices for malt delivery, receiving, and storage in brewery.
Malt Delivery and Receiving:
The method of malt delivery varies depending on the scale of the brewery. Small breweries typically receive malt in 25 or 50 kg bags, whereas larger craft breweries opt for bulk deliveries transferred to silos.
For bagged deliveries, careful attention should be paid to inspecting each bag for damage upon receipt. Any discrepancies in quantity or quality should be promptly documented. In contrast, bulk deliveries should undergo thorough inspection upon arrival to ensure the integrity of the malt and the accurate quantity received.
Storage Conditions and Facilities:
Maintaining optimal storage conditions is essential to preserving the quality of malt. Ideally, malt should be stored in a cool, dry environment with a temperature range of 50–70°F (10–21°C) and a relative humidity of approximately 50%.
When storing malt in bags, it is crucial to prevent moisture absorption by keeping bags away from walls and floors. Utilizing pallet racks can facilitate air circulation around the bags, mitigating the risk of mold formation and preserving malt quality.
For breweries with larger storage needs, investing in clean, dry silos is highly recommended. Silos not only accommodate larger quantities of malt but also offer advantages such as extended storage capability and labor-saving automation systems. Sight glasses should be installed to monitor grain levels, and regular visual inspections are advised to ensure optimal conditions within the silo.
