Using this tea is easy. Just boil some water and let it cool slightly for a minute or two. Then, place one of the pyramid-shaped tea bags in your cup and pour the hot water over it. Let it steep for 3 - 5 minutes depending on how strong you like your tea. Remove the tea bag, and enjoy your delicious cup of Osulloc Signature Earl Grey. As for storage, keep the tea in a cool, dry place away from direct sunlight. This will help maintain its freshness and flavor. Remember, don't leave the tea bag in the cup for too long as it might make the tea taste bitter. Also, if you have any allergies to citrus or vanilla, be aware of the ingredients in this tea.
