You may have noticed that there are several different ways to seal a wine bottle. There are corks made from bark, synthetic corks, twist off tops, and more. We even sell wine in pouches now (which has been a huge hit!). So what’s the difference, and which one is best? Let’s check it out. Traditional Cork It sounds obvious, but traditional cork is simply made from the bark of cork trees. We have some of the bark at the farm winery and if you ask we’d be happy to show it to you. It’s light and feels, well, just like cork. Still, people are surprised when they pick it up.
