Drinking in the winter is often an act of bleak necessity, a tool for maintaining normal levels of body temperature. But in the summer, liquid consumption becomes a thing of unbridled enjoyment.

Here to assist you in your sun-soaked cocktailing: The Ultimate Summer Martini Guide from Van Gogh Vodka (PDF).

This print-ready PDF has six unique recipes developed specifically for summer drinking by Van Gogh's own mixologists. Each features a different star from Van Gogh's portfolio of more than 20 painstakingly infused vodkas, so there's something for every taste.

Try a Starry Night cocktail--a blend of Van Gogh Açai-Blueberry Vodka and rosé Champagne--at your next summer barbecue, or make a pineapple-y Paradijs, the star of an alfresco brunch.

And to help you make the ultimate martini, Van Gogh Vodka is giving away some home mixology sets. Click here to enter for a chance to win one.

Just add sun and stir.
