How To Make Sun Tea
Packaged or bottled iced tea you buy is typically filled with loads of sugar and artificial colors, did you know you can make your own home brew that skips all that junk without turning on the stove or kettle? On hot sunny days, let the sun do all the work for you!

All You Need Is A Glass Jar With Lid, Bags of Tea, Water And Sun
Here’s how you make it (alternative Refrigerator Brewed Method and information on safety concerns are also listed below)…
Items Needed:
- 1 large glass pitcher or jar with lid (that will accommodate 8 cups of water)
- 6 to 8 regular size tea bags (or equivalent loose tea)
Directions:
- Fill pitcher with 8 cups of cold water then add the tea. Seal with lid.
- Place pitcher in a sunny location so it can sit out in full sun (getting 2 to 3 hours of sunlight–up to 4 hours if you prefer stronger tea).
- After brewing in the sun, strain out the tea and refrigerate until fully chilled.
- Add ice cubes and any flavorings before serving.
Is It Safe?

Add Fruit Slices & Herb Sprigs Like Mint After Tea Has Been Brewed And Not During Steeping Time
I also haven’t found any actual studies performed that have tested positive for bacteria growth in properly prepared sun brewed tea (prepared properly–limited time outdoors or at room temperature, properly cleaned storage/mixing items, refrigerated or iced right after brewed, etc.), as far as I know–there are no studies to refer to and safety concerns seem to be based on theories at this point.
I have come across arguments that tea’s natural anti-bacterial qualities and its caffeine content fights the bacterial growth during the few hours needed to brew the tea and to me that makes sense (along with proper initial preparation) and explains why this method for making iced tea has been favored by many and has been practiced for decades with no problem (or if there have been issues, at this time they appear to be undocumented).
Regardless, and with no definitive proof one way or the other to refer to, I do believe this “controversy” over sun tea safety is important to note and be aware of.
- Tea shouldn’t be brewed outside for longer than 4 hours and should be refrigerated or poured over ice right after brewing to bring it to a cool temperature quickly.
- Use a glass container so the sun can use the glass to heat the water to a higher temperature than it would with a plastic container.
- It’s very important to use clean jars, lids and utensils when making.
- Don’t add sugar before brewing since this can make a more friendly environment for bacteria growth, add it before serving instead (same applies for fruits with their natural sugar content).
- Do not reuse tea bags, remove bags and throw them out as soon as brewing is done.
- Don’t make large amounts to be consumed over time (even if it’s refrigerated), just make an amount that you will consume that same day.
- Some recommend boiling water for a few minutes to kill off any possible presence of bacteria then refrigerate until cold before using it to make sun tea.
- Signs of bacteria growth: ropey strands or strings have developed in the liquid or the result is a thick, syrupy tea that smells off (may indicate the presence of Alcaligenes viscolactis bacteria).
Steeping In The Refrigerator
If you’re concerned about potential health problems of brewing out in the sun but love the flavor of this method, you can still achieve the “sun tea” result by making Refrigerator Steeped Tea, here’s how:
- Prepare as noted above then instead of brewing in the sun, let it steep or brew in the refrigerator overnight (a minimum of 8 hours for best results). Just as a high temperature prevents bacteria growth, so does cold. Remove bags and serve.
Tips
- How to know when it has brewed long enough? You can tell by the color, when it’s as dark as you prefer your regularly brewed tea, it’s fine to stop brewing.
- Why does it take longer (or shorter) to finishing brewing from one day to the next? The time of day, intensity of the sun, brewing location, these all can play a factor when relying on the sun to make your tea.
- For strong flavor: Use more tea for brewing, or less water or brew longer.
- You can sweeten with sugar, honey or fruit juices just before serving.
- If you’re using a large glass pitcher to brew but it doesn’t have a lid, simple fix is to use plastic wrap fitted over the top with an elastic band to secure plastic in place.
- For a citrus flavored tea, try adding freshly sliced lemon, lime or orange when serving.
- You can strain out loose tea by pouring the liquid through a coffee filter or piece of cheesecloth. You can also make loose pouches out of cheesecloth to hold the loose tea–this will make it easier to remove the bits. Just tie the pouches closed with string.
- Iced tea prepared this way is preferred by many since it’s found to be more mild and less bitter in flavor than regularly brewed tea that has been chilled.
- Good to Know: Freeze some of the freshly brewed tea in ice cube trays and add these to the tea when serving, this will help prevent the iced tea from getting too diluted and watery from regular ice cubes. You can also try fruit juices and bits frozen in cubes for a different twist.










Does it make a difference which type of tea is used?
They brewing time may vary, but I don’t think so.
Oh my, Sun Tea. This used to be a favorite drink as a kid. My Mom always made it during the summer. And we never once got sick from the gallons of sun tea we would consume over the summer months lol.
This page does remind me that I should make myself some sun tea and enjoy a throwback to my childhood.
I’ve been making sun tea for many years and have NEVER had any problems with bacteria or getting sick using this method and I almost always leave my sun tea out for much longer than 4 hours. As long as I bring it in by sunset it’s still good. I like my tea strong. I’ve been known to forget it and see it outside the next day, I always dump it then, clean out the pitcher and start over if it’s left out over night. I use a 1 gallon glass jug with lid and finish the tea within a day or 2 and never add ice to it when sending it to the fridge, I only do that when I’m going to drink it and it’s still warm from the sun.
I say mix and match flavors and see what you prefer. I myself go for the classic black tea.
