What Happens When Coffee is Freeze-Dried? A Deep Dive into Richfield’s Process


Freeze-drying coffee is an intricate process that preserves the rich flavors and aromas of freshly brewed coffee. At Richfield, we have perfected this method to deliver exceptional freeze-dried instant specialty coffee. Here’s a detailed look at what happens when coffee is freeze-dried, and why it results in a superior product.


  1. Selection and Roasting of Beans


The journey begins with selecting high-quality coffee beans. At Richfield, we use premium Arabica beans known for their superior flavor profile. These beans are sourced from sustainable farms, ensuring both quality and environmental responsibility.


Once the beans are selected, they undergo a meticulous roasting process. The roasting is fine-tuned to bring out the natural flavors and aromas of the beans. This step is crucial as it sets the foundation for the coffee’s final flavor.


  1. Grinding and Brewing


After roasting, the coffee beans are ground to the perfect consistency for brewing. The ground coffee is then packaged in drip bags to ensure a consistent and convenient brewing method. This stage prepares the coffee for extraction, where the true essence of the coffee is captured.


  1. Flash Extraction Technology


Richfield employs state-of-the-art flash extraction technology to extract the rich flavors from the ground coffee. This advanced method focuses on achieving the top 18% extraction rate, preserving the delicate flavors and aromas that define our coffee. The extraction process is rapid and efficient, ensuring that only the best flavors are captured.


  1. Freeze-Drying Process


The extracted coffee is then subjected to the freeze-drying process. Here’s what happens:


Freezing: The coffee extract is frozen at extremely low temperatures, turning the liquid into solid ice. This step is crucial for preserving the coffee’s natural flavors and aromas.


Sublimation: The frozen coffee is placed in a vacuum chamber. Under these conditions, the ice sublimates, meaning it transitions directly from a solid to a gas without passing through a liquid stage. This process removes water from the coffee crystals while maintaining their structure and flavor.


The result of freeze-drying is coffee crystals that retain the full spectrum of the original coffee’s flavors and aromas. This method ensures that the coffee’s essence is locked in, providing a rich and aromatic cup when rehydrated.


  1. Packaging


Finally, the freeze-dried coffee crystals are packaged to maintain their freshness. Richfield uses eco-friendly packaging materials to reduce waste and promote sustainability. This ensures that the coffee remains fresh and flavorful until it reaches the consumer.


Benefits of Freeze-Dried Coffee


Flavor Preservation: The freeze-drying process locks in the coffee’s natural flavors and aromas, providing a rich and satisfying coffee experience.


Convenience: Freeze-dried coffee is incredibly convenient. It dissolves quickly in both hot and cold water, making it easy to enjoy a high-quality cup of coffee anytime, anywhere.


Long Shelf Life: Freeze-dried coffee has a long shelf life without the need for preservatives. This makes it a practical choice for those who want to enjoy premium coffee over an extended period.




When coffee is freeze-dried, it undergoes a meticulous process that preserves its rich flavors and aromas. Richfield’s dedication to quality, from bean selection to the final freeze-drying stage, ensures that our freeze-dried instant coffee stands out in terms of flavor, convenience, and sustainability. Choose Richfield to experience the pinnacle of freeze-dried coffee excellence.
