The United States Food and Drug Administration and the National Coffee Association recommended standard temperature for safe hot coffee is around 160°F to 165°F (71°C to 74°C). This temperature range is considered hot enough to be enjoyable while minimizing the risk of scalding or burning.
These agencies do not have specific regulations or guidelines solely dedicated to cold brew coffee. However, there are general principles and best practices for handling and storing perishable food products that can be applied to cold brew coffee to ensure safety.*
Cold brew coffee typically requires more time to prepare than traditional hot brew coffee. While hot brew coffee can be made in just a few minutes, cold brew coffee is made by steeping coffee grounds in cold water for an extended period of time, usually between 12 to 24 hours. The longer steeping time allows the coffee to extract more slowly and results in a smoother, less acidic coffee concentrate. After steeping, the coffee grounds are usually filtered out and the resulting concentrate can be diluted with water, milk, or other liquids and served over ice. While cold brew coffee does require more time to prepare, many coffee drinkers prefer its smoother, less bitter taste and lower acidity compared to hot brewed coffee. Additionally, the longer shelf life of cold brew coffee concentrate makes it a popular choice for those who like to prepare coffee in advance and have it ready to drink throughout the day. |

* These recommendations are based on general food safety practices:
Water quality: Start with clean, potable water to brew your cold brew coffee. Make sure the water source is safe and free from contaminants.
Brewing process: Follow good manufacturing practices and ensure that your brewing equipment and utensils are clean and sanitized. Cold brew coffee is typically brewed using room temperature or cold water over an extended period. Ensure that the brewing container is properly sealed and protected from any potential sources of contamination.
Filtration: After the brewing process, filter the cold brew coffee to remove any sediment or particles. This can be done using a fine-mesh sieve or a dedicated filtration system.
Storage: Store the cold brew coffee in a clean, airtight container in the refrigerator. This helps to inhibit the growth of bacteria and maintain the quality of the coffee. Cold brew coffee can typically be stored for a few days to a couple of weeks, depending on the specific recipe and preparation method.
Temperature control: Keep the cold brew coffee refrigerated at a temperature below 41°F (5°C) to prevent the growth of harmful bacteria.
Serve safely: When serving cold brew coffee, use clean and sanitized utensils, containers, and dispensing equipment to avoid cross-contamination. If you add any additional ingredients like milk or sweeteners, ensure that they are stored properly and do not exceed their recommended storage times.
Integrating Blockchain, Smart Contract-Tokens, and IoT to Design a Food Traceability Solution
Abstract: Information asymmetry exists amongst stakeholders in the current food supply chain. Lack of standardization in data format, lack of regulations, and siloed, legacy information systems exasperate the problem. Global agriculture trade is increasing creating a greater need for traceability in the global supply chain. This paper introduces Harvest Network, a theoretical end-to-end, vis a vie “farm-to-fork”, food traceability application integrating the Ethereum blockchain and IoT devices exchanging GS1 message standards. The goal is to create a distributed ledger accessible for all stakeholders in the supply chain. Our design effort creates a basic framework (artefact) for building a prototype or simulation using existing technologies and protocols [1]. The next step is for industry practitioners and researchers to apply AGILE methods for creating working prototypes and advanced projects that bring about greater transparency.
