The idea behind the revolution that took place in the Langhe in the 80s is a very complex and proufound topic, far away from the simplification of the introduction of barriques. This article written by Joshua Dunning, available on his website
https://wordonthegrapevine.co.uk/modern-traditional-barolo-piedmont/ is a very interesting read that considers all the aspects, putting everyhting into the right historic and social context.
As Joshua Dunning writes "The time has come for commentators, drinkers and those studious in wine to ditch this binary, acknowledge the far-reaching principles of the ‘modern’ revolution and expand their appreciation for the region in its current glory, not its former divide."
