I've noticed that this year too... 
 
  hi what is the best way of straining the vodka/berries, i pass it through muslin a couple of times but still ends up cloudy, tried coffee filter papers these aren't has good as the muslin, any ideas ? 
 
  
  
We strain the berries off through a sieve and then line the sieve with a doubled piece of kitchen towel roll and strain the liquid through this. Sometimes need to change the paper depending on how many litres you are doing.
