An improved hand operated citrus press is provided in direct operational combination with a liquid drinking vessel. The citrus press is provided removably connected to, and in fluid communication with, the liquid drinking vessel. The fluid contained within the drinking vessel can be infused with the essences from the ground or comminuted fruit from the citrus press. The fluid communication between the comminuting volume of the citrus press grinder assembly and the container allows these all natural ingredients to steep directly with the beverage, creating refreshingly flavored drinks that are as rich and natural in nutrients as its ingredients.
