We’re not sure if it’s the drink itself or just the adorable little glasses it’s served in, but we’ve been on quite the port kick lately. So you can be sure we’ll be attending the “Weekly Wine Down” event at Croma (269 Newbury Street, Boston) on March 7, from 6 to 7 pm. That’s when the series — featuring complimentary tastings — will focus on port and sherry. Call 617.247.3200 for information.
