The Wirral Distillery have produced yet another brilliant Gin, which is this, their Violetta Parma Violet Gin! 
They say they like to keep it 'old school' at their distillery, where they produce all of their gins in copper stills and use the 'Vapour Extraction Method'. This is where the botanicals are suspended above the boiling liquid in the still. The Wirral Distillery say that this creates 'fresh tasting vibrant gins without the sulphates that can be released when the botanicals come into contact with the liquid' and they're not wrong!

This is the shimmer free version.
