The vintage

2023 was a globally warm year, with light humidity and some cold periods.

The season started off hot and slightly humid with rain in late June. The team was out in force daily for green pruning and protecting the vineyard against mildew.

A warmer period proceeded, with some localized thunderstorms, requiring strict management of each plot, each row, each plant.


Harvest conditions in the morning were excellent. We chose to harvest in the morning due to sunshine and pleasant temperatures. Leaf thinning in early Spring allowed us to aerate the bunches and promote sunshine while protecting the aromas of the fruit.

We harvest in crates to allow meticulous and delicate respect of the fruit.

Our careful separation of the various press juice along with 100% barrel fermentation, delicate and consistent lee stirring: all promote the magnificent creation of AltO 2023: fresh, pure, smooth, mineral, vibrant…
