      The most common cause of the blue problem is an alkaline wash in
      contact with copper in the still. However I think in your case it
      is probably oversupply of yeast nutrients in the initial wort. If
      too much nutrient (e.g. DiAmmonium Phosphate or DAP) is used, you
      will get ammonia gas when you distill. The gas will dissolve in the
      water coming over and form the blue tint in your product. Redistill
      it with citric acid, about 1 ta/sp per litre. You can buy this
      cheap in the cakes section of any supermarket. This will fix the
      problem. Use nutrients sparingly, particularly fertilizers.
