Why freeze cider you may ask (I did) well let me explain.

There are two basic ways to distil alcohol, the normal method using a 'still' and cooling the evaporating vapour and the other method - freezing.

The principle is that alcohol freezes at a different rate to water and that by freezing, thawing and re-freezing you will concentrate the alcohol level of a given liquid . . .

 . . . or so I'm told.

   

Step one: Move the cheap cider to a clear bottle for observation reasons - that's so I can take pictures of course.  You'll have to pour away a couple of inches from the top of the bottle to allow for expansion.

You could just drink it out of course.

   
 

 

 

Step two: Put it in the fridge for a few hours.
The loaf of bread is not compulsory.

   
 

Step Three: After about four hours you should have frozen cider. You now want to let it thaw out a bit, just enough to turn half of the solid in to liquid.

   
 

Now you have to remove the ice to put the thawed cider back in the bottle, seems a waste I know, the worlds most interesting ice cubes going to  waste.

You guessed didn't you, it goes back in the freezer again.

   
   

The second thaw, next day and my cider lollipop is ready to melt.

   

After about 15 minutes we start to see results, the colour is already draining from the ice.

   
   
I can confirm without a shadow of a doubt that the finished result is much stronger that the original
It's not really cost effective, the end volume is less that a litre and of course any form of alcohol distillation
would be illegal in most countries except new Zealand (it takes their mind off sheep)

The examples shown here are of course mock-ups using coloured water (wink wink)
