I started to use an automatic coffee maker a friend left at my house to brew my Bengal spice (chai with roasted chicory instead of black tea). I put my tea bags in the glass pot.
I began setting it so it sat for an hour. Then for my birthday my son got me a new coffee machine that keeps the pot hot for 4 hours, now I steep my tea for about 2 hours.
I do that with herbal teas when it is after sundown (I drink almost all of my herbal teas cold) and I cannot make sun tea.
