在探索茶道的深奥之处，我们不仅要了解如何烹饪出最佳口感，还要掌握如何妥善保存铁观音，以保持其色香味。五大因素——水、温度、空气、光线和气味—are key to the quality of iron tea leaves. Though it's common for us to store tea in low temperatures and vacuum-sealed containers, the color, aroma, and taste may not be as perfect as when we first bought it due to the level of dryness after fermentation.
The standard packaging for iron tea is a 7-gram compressed package in a vacuum-sealed bag. If this is your preferred method, simply store it away from direct sunlight. However, if you want to achieve optimal preservation and extend its shelf life, consider storing it in your refrigerator at -5°C.
Even though iron tea has been dried and packaged in compressed form, it doesn't mean that can be stored forever. It's recommended that you put your new purchase straight into the fridge for consumption within half a year.
Some enthusiasts might wish to delve deeper into various methods of preserving their precious iron tea leaves. Two effective approaches are:
The "abstraction-charging-nitrogen storage" method: Replace air with nitrogen gas inside sealed containers to preserve the freshness of tealeaves under anoxic conditions.
Low temperature storage: Prevent oxidation by keeping tealeaves at below-freezing temperatures.
For larger quantities of tealeaves, specialized cold rooms should be built with proper ventilation and insulation against moisture.
In summary:
For less frequent consumption or smaller batches:
a) Use tin cans or double-layered metal containers lined with paper; seal tightly without any gaps.
b) Place two layers of nylon bags around these cans; tighten their openings.
c) Store them either in refrigerators or dehumidifiers for better results.
For simpler methods:
a) Use odorless and non-toxic nylon bags; wrap white paper around tealeaves before placing them inside bags.
Remove excess air by pressing gently on top before sealing tightly again.
Place another layer outside this inner bag while keeping everything within an insulated container like aluminum tins.
By following these guidelines regarding containment material choice (preferably non-reactive), location selection (avoiding light exposure), humidity control (keeping away from damp environments), temperature management (maintaining low temperatures), all factors will work together towards preserving our treasured teas through data-driven strategies rooted deeply within traditional knowledge passed down through generations practicing Tea Etiquette.
