History and Origins
Giuseppe Maria Sesti purchased the abandoned 13th-century Castello di Argiano in 1975, but the formal estate was not established until 1987. The first vineyards were planted in 1991, and daughter Elisa Sesti joined the operation full-time in 1999. Giuseppe's background in astronomy shaped the estate's philosophy from the start, directly influencing its approach to both viticulture and cellar work.

Terroir and Vineyard
Sesti sits on the southern slopes of Montalcino near Sant'Angelo in Colle, one of the appellation's warmer microclimates, tempered by cooling ocean breezes. The estate covers 102 hectares in total, with only 9 to 13 hectares planted to vine. Soils are a layered oceanic sediment mix of limestone and sandy loam, which contributes a distinct floral character to the wines. Elevation sits at approximately 300 to 350 meters.

Philosophy and Farming
Sesti practices biodynamic viticulture without holding official certification. Vineyard management follows lunar cycles, a practice rooted in Giuseppe's astronomy background, and bottling is timed to the waning moon. No synthetic chemicals are used in either the vineyard or the cellar. This commitment to natural farming has defined the estate since its first harvests.
- Biodynamic farming without official certification
- Lunar-calendar viticulture drawn from Giuseppe's astronomy expertise
- Bottling performed on the waning moon
- Zero synthetic chemicals in vineyard or cellar

Sesti produces three 100% Sangiovese wines: Rosso di Montalcino DOC, Brunello di Montalcino DOCG, and the Brunello Riserva called Phenomena. The Riserva is released only in the finest vintages, and each release carries a unique label depicting an astronomical event from that harvest year. All wines are aged in large wooden casks (botti) rather than small barriques, reinforcing the estate's traditional approach. The style is described as robust and powerful yet refreshing, with significant aging potential.
- Three wines, all 100% Sangiovese: Rosso, Brunello, and Phenomena Riserva
- Phenomena Riserva released only in best years with vintage-specific astronomical label
