When I hear stories of multiple infusions I think 100ml pots several times. This is a story of a 1000ml pot six times. I used a small chunk of cooked tuocha about 8g which cost less than a dime. It sat on the bottom bubbled for about 30 sec then floated to the top. For the first three infusions it stayed clumpy. By the fourth it broke up. The leaves after the first infusion where molasses burnt black. By the sixth infusion the taste and color were weak but drinkable. I actually think a small portion of the tea leaf is actually disintegrating to maintain the color and taste of each infusion. I didn't start out with that much leaf and so little at the end I just tossed it down the drain instead of the flower bed.
