M. A. Signature Vodka is a spirits manufacturer based in Montreal, Quebec. They produce what they call a ‘Herbal Infused’ Vodka which is at its heart, a Canadian grain vodka, that has been infused with a rhizome herb called curcumin (a component of turmeric) also called curcuma longa. This herb has a distinctly earthy flavour. It is somewhat bitter, somewhat peppery, and perhaps a little like ginger or mustard. As far as I can tell it has many culinary uses including being used as an ingredient for Indian curry powder.
If you visit the Hang Over Free Vodka website you will see that it is the same as the website for Signature Vodka. That is because Signature Vodka promotes itself as an infused ‘hangover free’ vodka. In fact, the Signature Vodka website devotes a great deal of space to the hangover free concept, as well as other reputed medicinal benefits of curcumin.
The nature of the Signature Vodka website prompted me to email the company and try to get some more information about the herbal infusion. What I was told, is that the infusion is in such small quantities that the FDA, the LCBO and the SAQ could not actually find it using their regular lab tests. I will be honest and say I really do not know what to make of all of this; therefore my review, for the most part, ignores the herbal infusion and instead concentrates on the merits of this spirit as a Premium Vodka.

The Pemberton Distillery is located in the heart of the Coast Mountains, an area known for its massive ice caps and pure glacial streams. The spirit the distillery produces, Schramm Organic Vodka debuted in August of 2009 as an authentic sipping vodka which is produced from whole organic potatoes (grown just 15 km from the distillery in the Pemberton Valley). The Master Distiller, Tyler Schramm, studied a Masters of Science in Brewing & Distilling at Heriot-Watt University in Edinburgh, Scotland. He focused his University thesis on the complex art and science of potato vodka distillation with the goal to prove that vodka could be just as rich and complex as a single malt scotch.
