A while back, at a traditional bar in Madrid, the owner recommended a very special drink recipe to me: red wine with onions. Initially, I found this combination quite strange, but after trying it, I discovered the effects were genuinely impressive, particularly for improving sleep quality.
The Preparation Method is Simple
The ingredients needed are actually quite straightforward - mainly quality Spanish red wine and fresh onions. I usually choose red wine from the Rioja region because its tannin content is moderate, perfectly balancing the sharp flavor of onions. Purple onions are preferable as they offer higher nutritional value.

The preparation steps for red wine infused onions are as follows: slice one medium-sized onion into thin pieces, place them in a clean glass bottle, then pour in 500ml of red wine. Seal and store in a cool place for one week. Gently shake a few times daily to allow the onion’s active compounds to fully release into the wine.

Consumption Guidelines and Precautions
You can drink 30-50ml each evening after dinner, but remember never to consume on an empty stomach. From my personal experience, after drinking continuously for two weeks, I noticed a significant improvement in sleep quality, and my digestion also became better than before. However, this recipe isn’t suitable for everyone, especially friends with alcohol allergies or gastrointestinal conditions should try it cautiously.
Finally, I’d like to mention that while this traditional recipe is widely popular in Spanish folk culture, it does contain alcohol, so everyone should decide whether to try it based on their own physical condition.
