Always wanted to make wine or just want to know more about what differentiates one vino from the next? Wanna feed your brain and your tummy, munching on chocolate while learning some of the lore surrounding this ancient treat? The Museum of Discovery's monthly Science after Dark event is tomorrow, May 30, from 6 to 8 p.m. It's 21 and up, $5, and the theme is "Wine and Chocolate." You'll learn how to make wine and what specific extracts and scents mean, complete with taste samples. If chocolate is more your thing, you'll be able to try Xocolatl, the Aztec drink served to Hernan Cortes, you'll learn to make (and be able to sample — yum!) truffles, and you'll learn about the blood/brain chemistry that happens when chocolate and wine are paired. It's free admission for museum members, and if you want more vino than a sample, there's a cash bar. Go here for more info.
