River temperature, this is the best temperature because it means you are on the river.
Pig's Eye Pilsner is one of the best river schwags available.
The beauty of Pig's Eye is that cold it tastes like average beer and at 60f it tastes the same.
There is no quality/taste degradation with increased temperatures.
An additional favorable aspect of Pig's Eye is that it is inexpensive.
**A warning, do not take Pig's Eye Red or Lean on the river as these do not have the same delta T properties as Pig's Eye Pilsner.
