What are the skills of how to preserve West Lake Longjing tea?

1. tin can storage method: tinplate double-cover colored tea supplied by the market is selected as the container. Before storage, check whether the tank body and the tank cover are sealed to avoid air leakage. When stored, dry tea leaves should be canned and the cans should be tightly packed. This method is convenient to use, but it is not suitable for long-term preservation.

2. Storage method of the ceramic jar: select a dry and sealed ceramic jar, wrap the tea leaves with kraft paper, put it around the jar, put a lime bag in the middle, put the tea bag on it, and wrap it tightly with cotton after filling the jar. Lime should be replaced every 1 to 2 months. This method makes use of the hygroscopicity of quicklime to protect tea from moisture, with good effect, and can maintain the quality of tea for a long time, especially for some precious tea such as Longjing and Dahongpao. This method is particularly suitable.

3. Food bag storage method: firstly, wrap the tea with clean and odorless white paper, then wrap a piece of kraft paper, then put it in a plastic food bag without air holes, gently squeeze it to squeeze out the air in the bag, then tie the bag mouth with a soft rope, take a plastic food bag, put it outside the first bag, gently squeeze it, squeeze the air in the bag into the bag tied with a rope, and finally put it into a dry and odorless closed iron drum.
