Hot brewing with tea bags:

1. Bring 1 quart of water to a boil on high heat and add the tea bags.
2. Lower the heat and gently simmer for 5 minutes.
3. Fill the pitcher with 1 quart of cold water and pour the tea into the pitcher. (You can discard the tea bag first but I leave it in for a stronger flavor).
4. Refrigerate until ready to drink.

Cold brewing with tea bag:

1. Place the tea bag in a pitcher with 2 quarts of water.
2. Refrigerate for about 2 hours and enjoy.

Brewing from barley grains:

1. Pour 1 quart of  water into a pot and bring to a boil over high heat.
2. Add the barley grains to the pot and lower the heat to a gentle simmer.
3. Cover with a lid and simmer for 5-15 minutes. The longer you simmer, the stronger the taste. 
4. Pour the tea through a strainer into a pitcher filled with 1 quart of cold water.
5. Discard the barley grains. Refrigerate until ready to serve.
