People often assume sweet tea barely has caffeine. In practice, I treat it as a caffeinated tea that can lean mild or fairly strong depending on how it is brewed.
That is why I read it as a range, not a fixed number. Steep time, tea strength, and serving size can change the cup more than the sweetened flavor suggests.
I’ve included a basic Southern sweet tea recipe at the end if you want more control at home.
If caffeine matters to you, the useful part is how much sweet tea can swing from batch to batch.
Does sweet tea contain caffeine? (How much explained)
In short, caffeine is in sweet tea, but the amount can vary depending on many factors, including the type of tea leaves used, the brewing time, serving size, and more.
On average, it is estimated that homebrewed sweet tea contains 2.56 mg of caffeine per fluid ounce – that means around 41 mg of caffeine per average cup or serving.
Cold sweet tea is easy to drink fast on a hot day, which is one reason I do not judge it by taste alone.
Because it starts with brewed black tea, I still count it as caffeinated even when the sweetness makes it feel lighter.
It is worth noting that the FDA suggests that the average healthy adult can consume 400 mg of caffeine a day or about 4-5 cups of brewed coffee.
Caffeine is usually moderate, but bottled, takeout, and homemade versions do not match one another.
Arizona Sweet Tea
I treat AriZona sweet tea as a rough range, not an exact count. AriZona lists sweet tea at 9 to 11 mg per 12 fluid ounces, which works out to roughly 6 to 7 mg in 8 ounces or 12 to 15 mg in 16 fluid ounces.
Gold Peak Sweet Tea
Gold Peak sweet tea is about 44 mg per 16.9 fluid ounces, which I read as a standard bottled tea rather than a high-caffeine one.
Pure Leaf Sweet Tea
Pure Leaf sweet tea is listed at about 57 mg per 18.5 fluid ounces, so I put it in a somewhat higher range than Gold Peak once I compare serving sizes.
Lipton Sweet Tea
I put Lipton Southern sweet tea on the lower end.
At 24 to 26 mg per 20 fluid ounces, it sits below most homemade versions and well below stronger bottled teas.
Sweet Leaf Tea
Sweet Leaf sweet tea is much higher, at about 69 to 88 mg per 18.5 fluid ounces. That is where I stop thinking light tea and start reading it like a caffeinated drink.
McDonald’s Sweet Tea
McDonald’s sweet tea is 50 mg per 16 fluid ounces, which puts it in the middle for me.
Chick-Fil-A Sweet Tea
Chick-fil-A’s sweet tea is listed at 62 mg per 16 fluid ounces, so I put it toward the stronger end.
Dunkin Donuts Sweet Tea
Dunkin’s sweet tea is around 45 mg per 16 fluid ounces, so it lands near the middle and close to some bottled options.
Publix Sweet Tea
Some decaf sweet teas sold at Publix use decaffeinated tea leaves, so I treat them as lower caffeine, not zero. That wording matters when I am trying to keep caffeine down.
Crystal Light Sweet Tea
Crystal Light Sweet Tea is listed at about 15 mg per serving, so I compare it with lighter drinks rather than brewed sweet tea.
What exactly is sweet tea? (Benefits & how to make it yourself)
Sweet tea usually starts as hot black tea, then gets chilled and sweetened. That first brew is where most of the caffeine variation starts.
Most versions use tea bags or loose leaf steeped in hot water, then sugar and more water before chilling. If I steep too long or make the concentrate too heavy, the cup comes out stronger.
It is usually poured over ice and often finished with lemon. Sweetness hits first, but the tea still shows through when the brew is strong enough.
I tend to think of sweet tea as an afternoon drink, so I pay more attention to caffeine and sugar than to vague health talk.
Homemade Sweet Tea Recipe
Making sweet tea at home is simple once you watch steep time and dilution.
Here is the basic sweet tea recipe I would start with, then adjust for strength and sweetness.
Equipment:
Ingredients:
Method:
- 1Bring four cups of water to a boil on medium heat
- 2Once boiling, remove from the heat and gently drop your black tea bags into the water
- 3Let the tea steep for at least 15-20 minutes
- 4Add the sugar and baking soda to the pitcher while you wait
- 5Prepare your garnishes while you wait (optional)
- 6Stir the water with the wooden spoon and remove tea bags, pressing to the side as you remove them to get as much tea as possible.
- 7Add the warm tea to the pitcher and stir with a long spoon until the sugar and soda completely dissolve.
- 8Add the rest of the cold water to taste.
- 9Place the pitcher in the fridge for at least three hours or, ideally, overnight.
- 10When ready to serve, add ice to your glasses and pour the tea equally between them.
- 11Add your garnishes and straws (optional) and serve immediately.
I change this kind of recipe by adjusting tea strength first, then sweetener. Swapping in decaf leaves or changing sugar is the easiest way to move caffeine without changing the whole drink.
Caffeine level in sweet tea vs other drinks
Sweet Tea vs Coffee
Tea leaves and coffee beans both contain caffeine, so I do not compare drinks by ingredient weight alone.
The average coffee bean is estimated to have around 1-10 mg of caffeine, whereas black tea leaves have an estimated 47 mg of caffeine.
Once brewed, tea and coffee usually land at different cup strengths, with coffee often more concentrated. I use that as a rough guide, not a hard rule, because brewing method changes the number quickly.
I watch caffeine across all my drinks because sweetness or mild flavor makes it easy to underestimate.
Sweet Tea vs Iced Tea
I separate sweet tea from iced tea by sweetness and by whether black tea is the base.
Iced tea is usually chilled over ice and may be unsweetened or lightly flavored.
Honey or lemon juice is often added after brewing, once the tea is poured over ice.
Sweet tea is usually made with black tea, while iced tea can use black, green, white, or herbal tea.
That wider base makes iced tea less predictable for caffeine than sweet tea.
Sweet Tea vs Coke
I compare sweet tea with cola more than you might expect because both are sweet, cold, and easy to drink without checking the label.
Let’s examine the caffeine content of common Cokes.
Cola caffeine varies by brand, so I read the label instead of assuming all colas sit in one range.
Its caffeine can overlap with sweet tea, which is why serving size matters more than the category name.
How to reduce caffeine in sweet tea drinks
Some people barely notice caffeine, while others feel it quickly. I keep that in mind because the same glass can feel different from one day to the next.
If I want less caffeine, I change steep time, tea strength, or tea type before anything else.
Those changes also affect flavor, so I usually adjust sugar or citrus with them to keep the drink balanced.
FAQs
Does sweet tea keep you awake?
Whether sweet tea keeps you awake depends on how much you drink, how often you have caffeine, and how late you drink it. My usual habit is to stop a few hours before bed, but timing still depends on sensitivity and total caffeine.
How much caffeine is in home-brewed sweet tea vs takeout sweet tea?
Takeout sweet tea can vary a lot by brand and recipe, so I treat the menu as the first clue. If I cannot see a caffeine number, I ask what tea they use, how strong it is, and whether it was brewed or made from concentrate.
Is decaffeinated sweet tea as good as regular sweet tea?
Decaf sweet tea still leaves room to adjust sweetness, lemon, and tea strength, so I reach for it when I want flavor with less caffeine.
How much sugar is in sweet tea?
Sugar can change how strong tea tastes just as much as the caffeine can. At home, I adjust sugar separately so I can taste the base first.
Does Deep Eddy Sweet Tea Vodka have caffeine?
Yes, but decaf sweet tea is not always zero caffeine, so I still check the label when one is available.
Conclusion
Yes. It depends on the leaves and how the drink was made, so I treat sweet tea as a caffeine-containing drink unless the label says otherwise.
That mix of tea flavor, sweetness, and ice is part of why sweet tea stays popular year-round.
Whether I buy it bottled or make it at home, I still look at serving size and tea strength before I assume the caffeine is light.
