(WTVR)–– All wine isn’t created equal, and neither are all wine toppers. This is what a new UC Davis study wants to prove. Most people assume corks are better than synthetic, and both are better than a screw top; but others argue that’s not true. It’s a taste test to please the pallets of all the winos out there. “We bottled so many different bottles,” said Andrew Waterhouse, UC Davis wine expert. Six hundred bottles of wine on the wall, 200 with each cork, all to learn if the cap will cost you in flavor. “There was one my friends and I tried to open with a corkscrew without realizing it was a screw top,” said wine lover Sneha Patel.
