Ciclo Vinho is a notable wine producer located in the Alentejo region of Portugal, an area with a rich history of viticulture that dates back thousands of years. The Alentejo region has been a significant part of Portugal's wine history, with evidence of vine cultivation and winemaking dating back to the Tartessians, an ancient civilization in the Iberian Peninsula. The region has experienced various cycles of prosperity and decline, influenced by historical events such as the Roman occupation, the War of Restoration, and the phylloxera epidemic. Despite these challenges, the Alentejo has seen a resurgence in viticulture, particularly in the mid-20th century, leading to a renewed interest in its wines.

Joachim Roque and Ana Paulino are the winemakers behind Ciclo Vinho. They have distinguished themselves by their commitment to producing natural wines, emphasizing sustainable practices in its winemaking process. The focus on sustainable winemaking at Ciclo Vinho includes the use of natural fermentation processes and minimal intervention techniques, which help preserve the natural flavors and characteristics of the grapes. This method not only enhances the quality of the wine but also reduces the environmental impact of production. By prioritizing sustainability, Ciclo Vinho contributes to the preservation of the Alentejo's rich winemaking heritage while also setting a standard for future generations of winemakers in the region.
