CWW – Let’s talk about… The greenest solution: bottle reuse, with Porto Protocol with Diana Snowden Seysses, Marta Mendonça and Muriel Chatel

April 23 @ 5:00 pm - 6:00 pm

CWW – Let’s talk about… Rosé: a simple wine that’s full of mystery, with Porto Protocol with Diana Snowden Seysses, Marta Mendonça and Muriel Chatel moderated by L.M. Archer. 

Tuesday 23rd April at 5pm BST

Join us for a discussion on bottle reuse solutions to date with three members of Porto Protocol, Diana Snowden Seysses, Marta Mendonça and Muriel Chatel, moderated by L.M. Archer (featured in header image).  They will share information gathered at the 2023 London Wine Fair where 20,000 bottles were collected and more than 1,000 fully examined for characteristics ranging from shape and weights to rim thickness and label type, to assess potential for reuse. Alongside this work and the questions raised by it they will look at reuse and waste reduction initiatives worldwide and how these can impact on wine’s carbon footprint in the future.

All three speakers are actively involved with Porto Protocol, the largest global wine  community committed to knowledge sharing and collaborative solutions for climate action.
