Do hops need to be cured?

Answered by Randy McIntyre

Hops need to be cured or dried after they are harvested. Curing is an essential process in hop production as it helps to preserve the quality and prolong the shelf life of the hops. During the curing process, the hops are dried down to a specific moisture content to prevent spoilage and maintain their desirable characteristics.

The curing process typically involves spreading the freshly harvested hops in a thin layer on a drying floor or in a kiln. The hops are then subjected to controlled airflow and temperature to remove the moisture content. This drying process can take several hours to a few days, depending on the drying method used and the ambient conditions.

The optimal moisture content for cured hops is usually between 8 to 10 percent. This moisture level helps to prevent spoilage and microbial growth, ensuring that the hops can be stored for an extended period without losing their quality. If the hops are over-dried and have a moisture content of 6 percent or less, they can become brittle and shatter, resulting in a loss of quality.

On the other hand, insufficiently dried hops can lead to oxidation and spoilage. Hops that have not been properly dried will start to turn brown and may develop a musty smell. In some cases, mold can also develop on the hops, rendering them unusable.

To ensure proper curing, it is crucial to monitor the drying process closely. This involves regularly checking the moisture content of the hops using moisture meters or other methods. The drying conditions, such as temperature and airflow, should be adjusted accordingly to achieve the desired moisture content.

In my own experience with hop production, I have witnessed the importance of proper curing. During one harvest season, we encountered a batch of hops that were not dried adequately due to a malfunction in the drying equipment. These hops started to turn brown and develop a moldy odor within a few days. It was a disappointing loss, highlighting the significance of proper curing in preserving the quality of hops.

Hops need to be cured or dried after harvest to preserve their quality and prevent spoilage. Curing involves drying the hops to a moisture content of around 8 to 10 percent. Over-drying should be avoided as it can cause the hops to shatter, while insufficient drying can lead to oxidation and mold growth. Proper monitoring and adjustment of drying conditions are essential to ensure successful curing and maintain the quality of hops.
