When picking the best tea tin, there are a few things to keep in mind. You want to pick a tea tin that will seal in fragrance while also keeping out moisture and sunlight. Read on to discover the key features of a great tea tin.   Airtight: Good tea tins will offer an airtight seal that locks in fragrance while protecting the loose tea from moisture that can damage and alter the flavor. Looking for airtight tea tin cans that feature a silicone seal or airtight locking mechanism to keep your favorite teas tasting the way they were meant to.   Opaque: The flavor of tea can also be affected by sunlight. Leaving tea sachets or loose tea lying around on the counter can cause the natural flavor profile to deteriorate over time. Looking for a tea metal tin container that is made of metal, dark glass, or wood including bamboo.   Large Opening: There's nothing worse than buying a beautiful storage container and realizing it's a total pain to try to get anything out of it. Looking for tea metal tin boxes that feature a wide opening that's big enough to easily fit a spoon or scoop. This will make it exponentially easier to dole out the right amount of tea without wasting precious leaves.   Size: If you love a particular type of tea — oolong tea bags or loose green tea for example — it may seem like a good idea to buy a giant container to store large amounts of your tea. However, containers that are too large will actually diminish the quality of your tea because the leaves will be exposed to air within the container. Instead, try buying only what you'll drink in the next few weeks and restock when your teas are getting low. This will ensure freshness and quality with each cup.
