According to MasterClass, if you have actually invested a bit of cash in your white wine, especially if those bottles are vintage and have a cork, keeping your bottle horizontally may be the method to go. The website goes on to describe this method keeps the cork moist, which can prevent premature aging. MasterClass goes on to share screw tops are less likely to have these issues, but horizontal storage also saves space and makes it easy to grab the bottle of your option when you are ready to crack it open.
That stated, specialists at Science Focus expose storing your bottles horizontally doesn’t necessarily make a difference. The site states: “science states otherwise” about this theory and goes on to explain that a bottle consisting of wine constantly has “almost 100% humidity.” They conclude that as long as there is red wine in the bottle, the cork is not going to dry and diminish. In addition, the outlet points to an Australian Wine Research Institute study performed in 2005, which discovered wine is largely unaffected by whether a bottle is kept horizontally or vertically. So, vertical storers can have peace of mind knowing they’ll enjoy their red wine all the very same.
