The Pot still head kit includes:
Clamp
Gasket
Column packing (small amount of copper fits inside the 2 inch area)
1 free bag of turbo yeast
This pot still head design was meant to be truly 'traditional', so no thermometer is used. Way back when, they did it 'old school', by smelling, tasting, and tweaking. This still head is meant to work that way.
