Square One is green through and through. Not only do they use only certified organic rye from North Dakota (they are actually certified by the USDA and by Oregon Tilth which has even stricter standards) and pure spring water to make their vodka, but their distillery is wind powered and their packaging is made using recycled materials and soy based ink. Their commitment continues in the distillery with the use of organic yeasts in the fermentation process. The purity of the ingredients means that this vodka requires only limited distillation and light filtration to preserve its delicate flavors.
The proof is in the tasting - this vodka is incredibly smooth, yet rich and creamy, with spicy rye aromas and a lingering peppermint finish.
