Can Muslims visit a vineyard or winery?

Grapes are a blessing

Grapes are halal and praised in the Quran. Allah even mentions them right next to the drink people make from them:

Scholars note that the verse calls the "good provision" good, but not the intoxicant. Wine was later forbidden completely. See Can Muslims drink alcohol?

What's fine

• Walking or cycling through vineyards in Tuscany, Bordeaux or Napa.
• Picking and eating fresh grapes, or buying fresh grape juice.
• Learning about farming, soil and history on a general tour.
• Photographing the landscape and having a halal lunch nearby.

What to avoid

The Prophet ﷺ cursed wine and the people connected with it, including the one who drinks it, serves it, sells it, presses it and carries it (Sunan Abi Dawud 3674). He also said that whoever believes in Allah and the Last Day shouldn't sit at a table where wine is being passed around (Jami' at-Tirmidhi 2801). So:

• Don't join tasting sessions, even "just to smell" or spit out.
• Don't buy wine as a gift or souvenir.
• Skip tours whose whole point is tasting and pairing.
• Don't take a job pressing, bottling or selling wine. See Can I do an internship at a company that sells alcohol?

Going with non-Muslim family or friends

If your family plans a vineyard day, you can usually go along for the walk and the meal. Politely sit out the tasting, enjoy grape juice instead, and explain simply that you don't drink. Most people will respect that. Some scholars advise avoiding wineries altogether to keep away from doubtful places, so if you feel uncomfortable, it's fine to suggest another outing.
