Quick Answer
For most herbal infusions, airtight tins are the best choice because they block light, air, and moisture while being durable and stackable. Jars work well if you use your tea quickly and love seeing the leaves, but they let in light. Bags are convenient but offer the least protection, so use them only for short-term storage. Choose based on how often you brew and how much you store.
Herbal infusions—think chamomile, peppermint, rooibos, and blends—are more delicate than many people assume. Their volatile oils and natural sweetness can fade quickly when exposed to air, light, and moisture. That's why choosing the right storage container is just as important as selecting quality leaves.
In this buying guide, we compare three common storage options: tins, jars, and bags. You'll learn how each affects freshness, how long your herbal teas can last, and get clear decision rules to pick the best container for your habits.
Why Storage Matters for Herbal Infusions
Unlike some aged teas, most herbal infusions are meant to be enjoyed within a year or two of harvest. Their flavors come from delicate essential oils that evaporate or degrade when exposed to oxygen. Light can also break down the pigments and compounds that give herbs their color and taste. Moisture is another enemy—it can lead to mold and spoilage, ruining an entire batch.
The ideal storage environment for herbal infusions is cool, dark, and dry, with minimal air exposure. An airtight container that blocks light and keeps out humidity will preserve the aroma and flavor much longer than a loosely sealed bag. This is why the material and seal of your container matter more than you might think.
- Store herbal infusions away from direct sunlight and heat sources like stoves or radiators.
- Always use a dry spoon or scoop to avoid introducing moisture into the container.
- Buy in quantities you can use within a few months to maintain peak freshness.
Tins: The All-Round Champion for Freshness
Metal tins, especially those with a tight-fitting lid, are the gold standard for storing loose leaf tea, including herbal infusions. They block out light completely, and when sealed well, they limit air exchange. Tins are also durable—they won't crack if dropped, and they stack neatly on shelves or in cupboards.
Rare Tea Company offers several empty tins designed for specific teas. For example, the Empty South African Rooibos Tin is a medium-sized tin perfect for storing larger bags of rooibos, while the Empty Rare Spanish Almond Blossom Tin is sized for that particular blend. These tins are not only functional but also attractive, making them great for gifting or organizing your tea collection.
Empty Rare Spanish Almond Blossom Tin
- Tins with a rubber gasket or a snug lid offer the best airtightness.
- Smaller tins are ideal for single types of tea, preventing cross-flavor contamination.
- Tins protect against light, which is crucial for light-sensitive herbal blends.
Jars: See-Through Convenience with Trade-Offs
Glass jars are popular because they let you admire the beautiful colors and textures of your herbal blends. They are also easy to clean and reuse. However, clear glass offers no protection from light, which can degrade the quality of your tea over time. If you choose jars, store them in a dark cupboard or use amber or cobalt glass to minimize light exposure.
Jars with airtight lids, such as those with a rubber seal, can be just as effective as tins at keeping out air and moisture. They are a good option if you go through your herbal infusions quickly and want to see what you have. But for long-term storage, tins are safer.
- Choose jars with a tight seal—clip-top jars are excellent for airtightness.
- Keep jars away from direct sunlight, even if the glass is tinted.
- Use jars for teas you plan to finish within a few months.
Bags: Convenient but Short-Lived
Many herbal infusions come in resealable foil bags, which are convenient and take up little space. While these bags are better than nothing, they are not ideal for long-term storage. The seal is often not completely airtight, and the bag can be punctured easily. Once opened, the tea is exposed to air every time you dip in a scoop.
If you buy herbal infusions in bags, consider transferring them to an airtight tin or jar as soon as you open them. This is especially important for blends with delicate flavors, like the Empty 21st Century Afternoon Tea Tin—though that tin is designed for oolong, the principle applies to any loose leaf. Bags are best for short-term storage or for teas you use daily.
- Transfer opened bags to an airtight container to extend shelf life.
- Use clips to seal bags tightly if you must keep them in the original packaging.
- Avoid storing bags near strong odors—they can absorb them.
Decision Rules: Choosing the Right Container
- If you drink herbal tea daily: Choose a tin or jar with an airtight seal that you can easily access. A medium tin like the Empty South African Rooibos Tin is ideal for frequent use. Prioritize convenience and airtightness.
- If you buy in bulk or want long-term storage: Opt for a tin that blocks light and seals tightly. Tins are more durable than jars and provide better protection over months. Tins are the safest bet for longevity.
- If you value seeing your tea: Use a glass jar with a tight seal, but store it in a dark place. This works well for teas you'll finish within a few months. Jars are fine for short-term use.
- If you're storing a single specific blend: Consider a dedicated tin that matches the tea, like the Empty Rare Spanish Almond Blossom Tin for that blend. It ensures the right size and adds a nice aesthetic. Matching tins enhance organization and giftability.
