Every time you enjoy a cup of tea, have you ever wondered how long does loose tea leaves stay fresh? Actually, the freshness of loose tea leaves depends on how you store them and the characteristics of each grade.
This article will bring you specific answers about the factors that affect the quality of tea products and give some tips on how to store the teas in the right way.
1. Explanation about how long loose tea will last
In fact, loose tea does not have an expiration date, so it is no exact answer for “how long does loose tea stay good?”. Shelf-life of loose leaf tea shown on product covers means the best time to use the tea. Over time, loose tea will lose its aroma and quality due to the oxidation process, except for Pu-erh tea.
Let us take some examples of how time will affect each type of tea:
The process of producing green tea is without fermentation. Therefore if we do not store the tea properly, the tea quality can degrade quickly. Green tea should be packed in a vacuum bag to keep its aroma and quality for 2 – 3 years. When the bag is opened, we should use it up within several weeks.
For black tea, it is highly fermented. Thus black tea will stay fresh much longer than green tea. Highly oxidized teas do not lose their flavor and aroma as soon as less fermented teas since they contain less moisture. If properly stored, black tea can last up to three years.
And how long to keep loose leaf Oolong tea? We can preserve Oolong tea for up to 5 years without losing its aroma if we handle it properly. If you open the container frequently, the tea’s shelf life will be shorter due to the damp air.
The most special tea when talking about shelf-life is Pu-erh tea. Pu-erh tea is thought to reach its peak taste in around 60 years, depending on storage circumstances, and then begins to decay over the next 40 years, after which there is little taste left.
In short, most loose teas do not retain the same quality and aroma as it is overtime. However, it rarely spoils to the point where it is unsafe to consume. Furthermore, different varieties of tea have a varying shelf life. Let’s go to the next part to see how we should store the tea properly to keep its quality for a long time.
2. How to store loose tea properly to stay fresh for long term
There ara some factors that influence how long the tea lasts, including light, temperature, air humidity, and odor of other foods. So how can we store the tea properly?

Tea should be stored in airtight and unclear containers such as tin cans, primary plastic containers and avoid being stored in transparent objects to keep fresh and good aroma.
Keep loose tea in a cool place
The high temperature can increase the oxidation process and then cause tea degradation. And at this point, you may wonder if we can store the loose tea in the fridge and wonder how long tea lasts in the fridge? However, storing tea bags in the fridge is not suggested since condensation can form, affecting the tea’s taste and flavor.
Keep loose tea away from food and spices
Loose tea absorbs the smell of other nearby things. Other smell doesn’t make loose tea lose it freshness, but causes to change its aroma. Thus, we should be careful when storing loose teas in the kitchen and should be stored in separate components. Do not store different tea types close together because their aroma may mix together.
Vacuum loose tea
Vacuum loose tea is possibly the best way to minimize the oxidation process and keep the tea quality as it is for a long time.

3. Signs to know a ruined loose tea
You will see the line “best before” date in loose tea packaging. It means you can taste the best quality of tea in the duration. Each type of loose tea has a different shelf life, so you should constantly inspect the tea leaves before drinking. Stop using tea when you find evidence of microorganisms such as mold, yeast, or bacteria because they are harmful to your health.
The most evident sign is a stale, strong odor emanating from your teapot. Another obvious sign is you may find mold in your tea. Fading tea aroma means your tea loses its quality.
Let’s take note of some helpful information as below to inspect the teas:
- Acidic Smell Or Taste – Bacteria produces an unpleasant odor that you will detect if your tea contains it.
- Tea leaves that are oozing. You must be cautious if your tea is damp and/or sticky.
Mold develops on tea leaves in a variety of ways. They all require moisture and will thrive in storage settings with relative humidity above 65 percent.
- Mold can have a strong odor, although certain types are less detectable. If you cup the tea and it has a bad aftertaste, it has most certainly succumbed to mold.
- Mold shows up as mycelium between your tea leaves. It comes in various colors, including white, light green, and bright yellow.
As long as you keep these indicators in mind, ensuring that the tea you drink is both tasty and healthy will be simple.
