Wine also known as Primitivo, familiarly

ZIN

This bold red is a California favorite, often paired with barbecue, and shares its name with a famous chemical element's symbol.

This clue refers to Zinfandel, a popular red wine grape that goes by the nickname "Zin" in casual conversation. It also mentions Primitivo, which is the Italian name for the same grape variety—so both terms point to the same wine. The answer is shortened to "ZIN" to fit the crossword’s concise style, matching the "familiarly" hint in the clue.
