I bought many different kinds of travel mugs, water bottles, and presses just so I can bring tea with me throughout the day. I often bring about two or three travel mugs or water bottles to work with me for that purpose (I store them in the fridge when I'm not sipping from them). So, I said 75%, though it may be even more. For the most part, I drink only brewed beverages.
Today's tea day was quite eventful. I've been staying at my parents' where all water for tea has to be heated on the stove in a pot, which I don't usually have patience for, so I've been going without for several days. But, today it was about 90 degrees outside, and we don't have air conditioning in the house, so I spent a good two hours brewing quarts of tea and tisanes that I threw in the fridge in preparation for another hot day tomorrow. I made two quarts of strawberry lemonade + apple lemon pomegranate rooibus, two bottles of jasmine pearls oolong + papaya green, a bottle of a Mexican cocoa brew, a bottle of pomegranate white, and two quarts of a concentrated masala and white chai blend. Tomorrow will be nice.
