Can you drink the juice from a jar of olives?

Olive brine is typically made with water, salt, vinegar, and other spices. While the brine is safe to drink, it is usually quite salty and sour. Some people enjoy drinking olive brine as a health tonic or as a hangover cure, but it is not for everyone. If you are curious about trying olive brine, start with a small amount and see how you like it.
