For example, Chiki Tea’s matcha is packaged at the source in specially-engineered airtight tin box packaging and flushed with nitrogen to eliminate oxygen oxidation and to keep the tea fresh until it is opened. In addition, a further barrier is affixed to the lid to absorb the oxygen after opening.   Gently open the tea metal tin canister over a sink as the matcha will “smoke” and leave a small residue floating in the air.   Once the matcha is opened, it’s time to start daily whisking because matcha does not age gracefully! Don’t be tempted to save it as long as you can because of the cost. The best flavors and aromas will be within the first three weeks if stored properly so that air is kept to an absolute minimum. Matcha should be kept in the fridge, optimally in the airtight canister, it has been packaged in and used within 3 weeks for the freshest taste, aroma, and color.   To use, take the matcha out of the fridge and wipe off any condensation. Have your tools out and ready, your preparation bowl and chasen heated, and then open the matcha metal tin canister, scoop out the desired amount, and quickly close the lid. Oxygen and moisture are the biggest factors in deteriorating all Japanese tea but especially matcha, due to the particle size.   Unopened matcha can be stored in the freezer for a year or longer but when it’s opened, promote it to the fridge and consume it quickly. It is possible to extend the freshness of the opened matcha by placing it in the freezer; however, because condensation is a matcha killer, the container needs to be wiped and left for a few minutes to stop the condensation buildup before opening. This is ideal if your 100g canister takes longer than a month to consume.          

Much like good coffee storage, proper tea storage is imperative to its shelf life, quality, and flavor. Learn how to keep your tea fresh and delicious with these easy tea storage tips. You'll have to consider the location, packaging material and packaging mechanism you're using to store your tea. Here are the best practices for each.   Location: · Store far away from anything with a strong odor. · Store in a dark cabinet or completely opaque container. · Keep delicate teas separate from strongly scented teas. · Avoid storing tea in humid areas of your kitchen or house.   Tea Storage Materials: · Use opaque packaging if possible.Tinplate is the best choice by the way. · Be sure your packaging is food-safe (for example, don't use a pencil case to hold tea). Itinbox® tea tin box packaging is quite food-safe and environmental. · Glazed ceramics, non-reactive metals, and opaque, non-leaching plastics all make great packaging materials. · Wood packaging may be a workable option, but be aware that many wood containers have odors that can influence the tea's taste. · The bags that suppliers sell tea in vary widely in terms of quality. For long-term storage, make sure your bags are multi-ply with an inner layer of foil or glassine (a substance similar to wax paper). This avoids contamination by water, air or grease.   Tea Storage Mechanisms A tight seal is key. If the mechanism can hold water, it can protect tea. Good options include: · Double lids tea tin (these are common with metal tea tin canisters). · Odor-free silicone seals (also common with metal canisters). · Multi-ply bags with resealable plastic 'zippers.'
