I need to make a tea( black, green or red) shader for cycles in Blender 2.76b. Coffee would be good. Or something that would get me moving in the correct direction. I would like a procedural shader and not have to take or find a texture based shader. I find that trying to figure it out by myself is not getting me anywhere. Not a math wiz here. And still very new to Blender. I have been looking online for tutorials of this type for a few days. And other than finding fluid dynamic and how to make choppy water haven't found much. If nothing is available, maybe will need to photo a cup/glass of tea and try to make from a texture. Any help would be appreciated.

Ps. I know what a node is and where they live in Blender. Though far from an expert.

This tutorial talks about setting up a coffee shader, at around the 50:00 mark.
