Having started out with the aim of working in tourism, Montone quickly decided that wine was more interesting and, following a trip to Montepulciano in 2008, switched his focus to wine and hospitality. In 2012, he completed a sommelier course in his native Italy and moved to London in 2013, where he first worked at Aqua Shard. From 2014 to 2016 he found himself working as junior then deputy sommelier at The Ritz, before moving on to Locanda Locatelli as assistant head sommelier. In 2017 he joined Berners Tavern, as head sommelier, and was later made director of wine. During this time, Montone has racked up an impressive array of awards and diplomas, including coming seventh in a competition of Italian sommeliers in 2015. He was a finalist in the 2018 Taittinger Sommelier of the Year competition, and in November he achieved his advanced certificate from the Court of Master Sommeliers.
He joined one of the most exclusive club in London, Maison Estelle as Wine Director in 2021. He also runs his own consultancy.
