Could they be just fermenting syrup to as high as they can go (15%) and then just adding ethanol to get the 49%?
Could that ever taste good?
It appears the price would be $2.40 for the concentrate and $.50 for the carbonation powder. For hard core hikers who will spend 10x for dehydrated food this is a bargain. Also quite the hero when everyone else is drinking Tang?
The end concentration always depends on the temperature you froze it at and the time it remains frozen, the nearer you can get to the alcohol freezing point and the longer the time it stays there, the more water will be frozen and the more solids will be separated. It is really not much different from distilling, except that in distilling you remove the alcohol from the water and solids by converting it to steam, here you separate the water from the alcohol by converting it to ice.
Concentration of up to 90% are possible though much more difficult to achieve than by distilling as the mechanical separation has to be performed at sub-zero temperatures.
@Tom, I doubt that hard core hikers would want to have alcohol in their rations, that would be just another sugar sink and sugar is something you don't have to spare on a hike.
