The market value of each bottle signed by Peter Sisseck is not based on marketing positioning, but on concrete agronomic factors.
A heritage of century-old vines at the heart of Dominio de Pingus
The estate’s quality is underpinned by a plot of old Tinto Fino (Tempranillo) vines, either ungrafted or derived from very old mass selections, ranging in age from 70 to over 100 years. These centenarian vines are planted in the distinctive clay-limestone soils of La Horra, combining a compact clay matrix in the subsoil (which regulates summer water stress) with surface limestone deposits (which provide the acidity essential for the wine’s pH). The deeply rooted root system extracts essential trace elements and compensates for the droughts of the Castilian Meseta. This aged vine stock gives rise to strict physiological self-regulation. Yields are naturally minuscule, regularly fluctuating between 9 and 12 hectolitres per hectare. Technically speaking, this amounts to barely half a bottle of juice per vine.
Biodynamics and harvest management at Dominio de Pingus
In order to preserve the biological activity of these fragile soils and to bring out the terroir to its fullest potential, the estate undertook a radical conversion to biodynamic agriculture, which was fully completed in the early 2000s. As a renowned estate practising biodynamics, it commands higher prices, reflecting its high standards and the quality of its produce.
The use of synthetic chemicals, herbicides and systemic treatments is strictly prohibited. Pest and disease management in the vineyard relies exclusively on preparations made from horn manure (500) and horn silica (501), combined with herbal infusions (horsetail and nettle) to stimulate the vines’ natural defences. Soil compaction is avoided through the return to horse-drawn ploughing. During the harvest, a selection is made directly in the vineyard, followed by a second manual selection on a sorting table in the winery. Only fully ripe grapes, free from any blemishes, are selected for winemaking.
The role of indigenous yeasts and wine ageing at Dominio de Pingus
The winemaking protocol in the cellar excludes the use of any artificial aids in order to preserve the integrity of the raw material. Alcoholic fermentation begins spontaneously, driven solely by indigenous yeasts naturally present on the grapes’ bloom. This technical choice rules out the use of selected external yeasts, which tend to standardise the aromatic profiles. Fermentation takes place in small, temperature-controlled stainless-steel tanks or in wooden vats.
