Onion Red Wine Infusion

Why people make this infusion

Onion soaked in red wine is a classic folk wellness remedy popular across parts of Asia and even Europe. In Chinese food therapy, onions are considered warm in nature and are associated with moving qi and blood — something loosely translated as improving circulation. Red wine, taken in small amounts, is similarly thought to gently warm and move blood. Together, they make a preparation that many older Cantonese households keep in the refrigerator as a daily tonic, particularly for those managing blood pressure or wanting to support heart health through food.

Method

1. Remove the dry outer skin from the onions — no need to wash them. Cut into rough chunks.
2. Place the onion pieces into a clean glass jar with a tight-fitting lid.
3. Pour the red wine over the onions, ensuring they are fully submerged.
4. Seal the jar and store in a cool, dark place (or in the refrigerator) for one week.
5. After one week, remove the onion pieces and store them in the refrigerator. The infused onion can be eaten as a side dish or used in cooking.
6. Keep the infused wine refrigerated. Aim to finish within a few months.

Nourilo’s Tips

Take approximately 20–50 ml per day. Non-drinkers should dilute with an equal volume of warm water, or warm the infusion gently for 5 minutes to reduce the alcohol content before drinking. The soaked onions are good to eat on their own or add to stir-fries. Store the finished wine in the refrigerator; there is no need to refrigerate the onions before soaking begins. Aim to finish within a few months for best quality.
