(TheDrinksBusiness) - A trial using first growth Bordeaux has shown how closure type affects a wine’s evolution over almost 10 years, and the results aren’t quite as expected. To better understand what motivates winemakers to choose a cork, screwcap or synthetic closure we spoke to three highly-respected figures for the August edition of the drinks business (pages 32-37), each of whom have opted for something different. Initially, however, we profiled one winemaker who has trialled different ways to seal his prized wines for almost 10 years in what must be the most high profile experiment in the history of the closure debate.
