New Research Reveals Insights on Cold Brew Safety

A recent study commissioned by the National Coffee Association (NCA) of the United States has provided valuable insights into the food safety aspects of using cold brew for in-store drink preparation.

The research aimed to assess the risks associated with cold brew and identify potential areas for improvement. By examining various factors, such as storage, handling, and microbial contamination, the study sheds light on the safety practices adopted by coffee shops and cafes.

Storage and Handling Practices

The study found that proper storage and handling of cold brew are essential in ensuring its safety. Coffee establishments that followed recommended guidelines for refrigeration temperature and duration demonstrated a lower risk of bacterial growth. It was evident that maintaining a consistent cold chain is crucial for preserving the freshness and quality of the cold brew.

Additionally, the research highlighted the importance of proper labeling and dating of cold brew containers. Clear and accurate information helps baristas and customers track the freshness of the product and prevents the consumption of expired drinks.

Microbial Contamination

The study examined the prevalence of microbial contamination in cold brew samples obtained from various establishments. While the majority of samples were within acceptable limits, some exhibited higher levels of contamination, indicating potential issues with cleanliness and sanitation.

To address this concern, the research emphasizes the significance of regular cleaning and sanitizing protocols for the equipment used in cold brew preparation. Proper maintenance and hygiene practices can significantly reduce the risk of microbial growth and ensure the safety of the final product.

Training and Education

Another key area highlighted in the study is the importance of training and education for coffee shop staff. Ensuring that employees receive comprehensive training regarding cold brew safety protocols and best practices is of utmost importance. By equipping them with the knowledge and skills necessary for safe preparation and handling, the risk of foodborne illnesses can be minimized.

It is recommended that coffee shop owners and managers invest in ongoing training programs that emphasize the importance of food safety, proper storage, hygiene practices, and regular equipment maintenance.


The recent research conducted by the NCA sheds important light on the food safety aspects of cold brew used in coffee establishments. By paying attention to storage and handling practices, addressing microbial contamination risks, and investing in staff education, coffee shops can ensure the production of safe and high-quality cold brew beverages. Prioritizing food safety is vital for consumer trust and maintaining a positive reputation within the industry.
