Chalk soils, north-facing slopes,
and 97-year-old vines. Planted in containers,
they have three branches that have
a lot of permanent wood and that have
grown year after year thanks to pruning.
The slope means that normal tractors
cannot be used, which means that
the work must be done using horses or
a hand-operated tiller. Productions of less
than one kilo and a balanced leaf surface
mean concentration and phenolic maturity.
