Luzianne family size iced tea bags are my go to for making a gallon or two of sweet tea.
It’s a mix of orange pekoe and and pekoe cut black teas and available in 24 and 48 count.
Be sure to check out my Sweet Tea recipe for how I make Sweet Tea. It’s easy to make and great for a hot day and ookouts.
It’s inexpensive if you can find it in your local grocery store compared to some other brands and it’s really good.
