If you weren’t one of our eagle eye readers that spotted them in yesterday’s Tasting Notes feature (there’s a hint after the jump), this should make things a bit more obvious. A collaboration between Nau and the BPA-free boffins at Kleen Kanteen, these stainless steel ($39) chalices are made from food-grade stainless steel and feature an electropolished interior and the ever-crucial stackability for easy packing. Only two other ingredients are required: your preferred outdoor spot and beer of choice. Pack of four.
