Can Cisa / Bar Brutal is hands down the best place for natural wine in Barcelona. You may have to wait for a seat for a bit, but it’s worth it to try their selection of all natural, low intervention wines from Spanish producers. It’s all in one location really but theoretically it’s split in too, with Can Cisa being the wine bar at the front and Bar Brutal being more of a sit down experience. You can get anything you want in both places so just grab any space you can, but we did like sitting at the kitchen counter if you can bag a space there. The food is non-traditional, a bit Spanish, and a little bit from almost anywhere else they fancy but it all adds up to a great meal. Grab the famous porchetta sandwich or just get some ham and cheese to go with all that delicious wine.
