  1. Prepare the negus mixture and let it stand until it is quite cold.
  2. Pour in a bottle of white wine.
  3. If desired, place the jug in a tub of ice and sweeten a little more to compensate for the cold.

Ice: Optional ice tub

Cook explicitly marks this as the summer-season adaptation of the hotter negus style.

Temperature management is the main point of divergence from the standard white wine Negus.
