What Is Sun Tea?

Sun tea is a fun summertime activity that people have enjoyed for decades. Sun tea is simply iced tea that is allowed to brew in sunlight for several hours. Sun tea is traditionally made using black tea such as Lipton or Luzianne. For your homemade sun tea, you can use any black tea you like or opt for herbal teas instead. The tea is often sweetened using sugar cane or brightened up with the addition of fruit.

The flavor profile of sun tea varies depending on what type of tea is used in the brewing process. In general, teas brewed suing sunlight tend to have a milder flavor than those brewed using hot water or boiling water. That's because sun tea never really gets above 130 degrees Fahrenheit. Even the most delicate teas such as white tea and green tea are brewed at 150 to 170 degrees Fahrenheit. Cold water does not develop flavors as well or as quickly as hot water.

The result is a mild flavored tea that can be accented by adding sweeteners or blending different tea flavors. Some of the most popular flavors include hibiscus, peach, and rosehip. Black tea leaves will add a stronger earthy flavor profile while green tea with lend a grassy and herbaceous note.

How To Make Sun Tea


  • 4 to 8 tablespoons of loose leaf tea or 4-8 tea bags
  • 1 gallon of spring water or purified water
  • 1 large glass container (a 1-gallon jar or larger is ideal)
  • Direct sunlight
  • Sweeteners (cane sugar, brown sugar, simple syrup, etc)


1. Start with a clean, disinfected 1-gallon container. Fill the glass container with water and add the tea bags. Cover with an airtight lid.

2. Place the clear glass jar in direct sunlight for 3 to 5 hours. It may be necessary to move the jar once or twice to keep it in the sunlight depending on where you live.

3. Bring the tea inside and refrigerate immediately once it reaches your desired flavor profile.

4. Sweeten the tea as desired.

5. Serve in glass mason jars and sip on a hot summer day. Do not store the sun tea for more than 24-32 hours.

This recipe can be even more refreshing by adding fresh mint leaves to the mix. The mint tea will add an invigorating aroma and crisp flavor. Additionally, you can add other herbs such as lemon verbena or lemongrass for a tart taste.

Risks Associated With Sun Tea

Some research shows that brewing tea in sunlight may encourage the growth of bacteria that can make humans sick (1)(2). While the risk is extremely low, it is higher than when the tea is brewed using boiling water or hot water. The vast majority of individuals who brew sun tea will not experience negative side effects when brewing this tea. That does not mean it is entirely risk-free.

There are several things you can do to ensure your sun tea is not contaminated with bacteria. We've outlined some tips below that you can use to brew the tea as safely as possible.

If you are still concerned, you can brew iced tea in the refrigerator instead of in direct sunlight. This method is known as cold-brewing. Cold brew tea takes longer to develop flavors than hot brewed teas. That's because the process uses time instead of temperature to draw out the tastes of loose tea or tea bags. You can also simply brew the tea using hot or boiling water and cool to room temperature before storing in the refrigerator.

Tips For Making Sun Tea

Don't Use Plastic

Plastic containers can alter the flavor of tea and may impact human health. Plastic containers may leach chemicals and unwanted toxins into the tea mixture when subjected to high temperatures. Instead, use only clear glass containers when brewing sun tea on a hot day.

Clean Your Tools Well

One of the best ways to avoid contaminating your sun tea is to use clean, disinfected tools. One of the most common ways that sun tea is contaminated is through the spout of the container. Make sure to clean the spout and spigot of the container well before and after each use. You can do this by hand or using a dishwasher. Make sure to take any pieces apart to get the deepest clean possible. If the container cannot be easily cleaned, choose a different vessel to brew your sun tea.

Use High-Quality Water

Most tea experts recommend brewing tea using filtered or purified water. That's because tap water can contain chemicals such as chlorine that alter the natural flavor profile of tea leaves, roots, and flower petals.

In the case of sun tea, it's particularly important to use high-quality water. Dirty or contaminated water sources may contain bacterial growth that will thrive when exposed to sunlight and warm temperatures. To avoid negative side effects, only use filtered or purified water when brewing sun tea.

Brew For 3-4 Hours

Sun tea should not be left in sunlight for more than 3-4 hours. Tea that is left out for longer has a higher risk of developing bacterial growth due to long-term warm temperatures. After the tea reaches your desired taste, bring it in and refrigerate immediately.

Only Brew Daily Amounts

Since the risk of bacterial contamination is higher with sun tea, most experts recommend brewing only what you will drink that day. This tea should not be stored for more than 24 to 32 hours. If you do not finish your sun tea, simply discard and brew a new batch the next time you crave the sweet tea.

Refrigerate After Brewing

Sun tea should be refrigerated after brewing. The cooler temperature of the refrigerator helps prevent bacterial growth. Make sure to keep the sun tea refrigerated and do not leave out – even if you are serving tea at a garden party. Bring the tea out of the refrigerator to serve and place it right back inside.

Discard If Necessary

Contaminated tea will appear thicker than normal. If you see long strings or a syrupy texture, discard the tea immediately. These are signs of bacterial growth, which may cause harmful effects to your health.

Sun tea is a wildly popular beverage in the southern states and coastal areas such as California. These regions receive hours and hours of sunlight that are ideal for brewing tasty teas. Harness the power of the sun and brew a tasty jar of sun tea today.
