I've made the original version several times, and I think it's too weak. My current variation boils 4 cups of water and steeps 3 family-size tea bags, then adds 1 cup of sugar and 6 cups cold water. I've made the peach version with this variation (but using 1/2 cup sugar), and I still taste little tea and a lot of peach nectar. Also, just know the color won't be clear and it will resemble a cider in color and consistency. So I remove less tea and add less peach nectar when I make it now. I still add the lemon juice to both versions.
The method is good, however I always use 3 family size bags and 2/3 cup sugar.
I always use Luzianne tea, it makes the best sweet tea.
A cup of sugar for 10 cups of tea? That's too sweet even by Southern standards, LOL. I use one cup of sugar per gallon of tea, and it is still really sweet. A gallon only lasts 2 days at most in my house. (this recipe only calls for 10 cups of water total. There are 16 cups in a gallon)
Having grown up in the South, I have to say this isn't exactly right. We always used more tea bags and 1.5 to 2 cups of sugar. Now that's "really sweet tea."
I used the Tazo brand of black tea for this recipe with the full cup of sugar and it turned out great! Very refreshing
