Aaron B - On preserving fresh roast specialty coffee beans

Описание: Aaron B - So, yeah, thanks for the letter. I found it interesting that you are planning to use your FiZZ GiZ dispenser to experiment with preserving fresh roasted coffee beans. Your suspicion that storing the beans away from light in a pressurized head space of pure, anhydrous CO₂ will extend the shelf life of the beans, preserving the "first week" freshness attributes that fresh roast specialty beans are famous for has been verified. Flushing out the air gets rid of pesky oxygen and moisture/humidity. Storing the bottle in a cabinet protects the beans from ultraviolet rays. And pressurizing the pure, dry CO₂ headspace surrounding the beans greatly slows down outgassing, preserving essential flavor elements. In your letter, you made reference to the Italian company, illy using nitrogen to pressurize cans of fresh roasted beans. I've read about them. They introduced the pressurized cans in the mid-to-late 30'ies. Interestingly enough, that was along about the time that modified atmosphere packaging was being studied (see    • Modified Atmosphere Packaging  ) here in YouTube. The benefits of that process have never been more fully realized than in its application to fresh roasted specialty beans.

Thanks for the feedback!
