The ergonomic thumb notch in the GoVino series is a worthwhile innovation. Testers, in the spirit of the mixed-used shatterproof glasses, enjoyed both Colorado microbrews and regional whiskies from the clear, BPA-free GoVino. A flexible rim took some adaptation as it felt breakable and spillable at first; no worries, though, as multiple trips have failed to mark the glass. Offered in four-packs, go with this reusable, recyclable glass for group gatherings.
