Is a Grist Case Necessary for Enhancing Your Brewery Efficiency?

Need a solution for storing your milled grain before mash-in?

Grist cases are storage vessels for crushed malt and key components in beer brewing. They are placed between the grain mill and the brewhouse, serving as an intermediate stop for crushed grain before it is introduced into the mash tun. The grist case is part of the brewery’s grain handling system, which also includes the grain auger, grain mill, and grist hydrator.

Several key advantages:

– Greatly reduces the risk of equipment failure in the brewery’s grain delivery system, which can cause costly delays or underfilling.

– Connects directly to the auger, saving labor.

– Greatly reduces grain dust.

– Allows for direct mashing in one go.

– Provides long-term cost savings compared to more expensive pre-cracked grain.

Where can we install the grist case in a brewery?

The delivery of grains to the brewhouse can be approached in various ways, especially when dealing with larger brewhouse volumes. This depends not only on the equipment available but also on the allocation of floor space, especially if the intended space has a small footprint.

By adding a grist case, you can prepare a full batch of grist in advance, ready for your brew day. You no longer need to worry about issues at the mill or milling while trying to mash in simultaneously.

There are several different configurations available:

– Grist cases can sit on the ground next to the brewhouse.

– They can be equipped with a floor-standing mill and a flexible auger. This setup delivers the crushed malt to a silo mounted above the mash tun, resulting in faster mash-in times.

– A malt mill can be mounted directly above a grist case, or it can be divided into stages for milling and grist collection. This allows the brewer to run the mill and achieve the perfect crush for all grains before starting the mash. Once milling is complete, an auger system can be activated to deliver the grist directly to the mash tun. This approach allows for precise control of strike temperature and liquor-to-grist ratios.

If you plan to brew multiple batches in a day, a grist case provides an accurate solution for ensuring correct grist weights when using larger malt bags (ton bags) or even a grain silo. With larger grist cases, the legs can be mounted on load cells, allowing you to weigh the exact amount of grain needed before sending it for milling or into the mash tun.
