A sugar-free taste of the south: keto sweet tea is exactly what a hot afternoon calls for — family-size black tea bags, erythritol, and a few drops of stevia brewed by the gallon. It pours over ice with lemon wedges and never gets watery with sugar guilt. One pitcher keeps a full week in the fridge.
A Sugar-Free Taste of the South

Growing up, every porch visit and family gathering featured a glistening pitcher of this liquid gold. This recipe captures that authentic, down-home flavor you crave, but with a modern, sugar-free twist. It’s perfectly sweet, but feel free to adjust the erythritol to a ½ cup if you prefer a more subtle sweetness.

Pro Tips
• Don’t over-steep. Steeping black tea for much longer than 20 minutes can release excess tannins, resulting in a bitter-tasting tea.
• Dissolve sweeteners while hot. Erythritol dissolves best in the hot tea concentrate. Adding it to cold tea will result in a gritty texture.
• Prevent cloudy tea. For crystal-clear tea, allow the hot concentrate to cool for about 15-20 minutes before combining it with the cold water.
• Infuse with flavor. Add a few sprigs of fresh mint to the saucepan along with the tea bags for a refreshing mint-infused sweet tea.
FAQ
Q: Why is my sugar-free sweet tea cloudy
A: Cloudiness often happens when hot tea concentrate is mixed with cold water too quickly. For crystal-clear tea, allow the hot concentrate to cool for about 15-20 minutes before combining it with the cold water in your pitcher.
Q: Can I use a different sugar-free sweetener
A: Yes, while this recipe is optimized for erythritol and stevia, you can experiment with other sugar substitutes. A 1:1 sugar replacement like allulose or a monk fruit blend should work, but be aware it may slightly alter the final taste and sweetness.
Q: My sweet tea tastes bitter what did I do wrong
A: A bitter taste is usually caused by over-steeping the tea bags. Steeping black tea for much longer than the recommended 20 minutes releases excess tannins, which creates bitterness. Stick to the steeping time for the best flavor.
Q: How long does this sweet tea last in the fridge
A: You can store this sugar-free sweet tea in a covered pitcher in the refrigerator for up to one week.
Pro Tips
- Dissolve the sweeteners while the tea concentrate is hot — erythritol stirred into cold tea never fully dissolves and leaves a gritty texture.
- Let the hot concentrate cool 15–20 minutes before combining it with the cold water; this is what keeps the finished tea crystal clear instead of cloudy.
- Steep the tea bags for exactly 20 minutes — much longer releases excess tannins and turns the tea bitter.
- For a refreshing mint-infused version, add a few sprigs of fresh mint to the saucepan along with the tea bags.
- Store the finished tea in a covered pitcher in the refrigerator for up to 1 week and serve over ice with lemon wedges.

This sugar-free take absolutely is — a 16-oz glass has just 5 calories and 1 g of carbs, sweetened entirely with erythritol and liquid stevia.
Why is my sweet tea cloudy?
