In the northeastern part of Achaia, in the northeastern Peloponnese, lies the PGI Slopes of Aigialia (ΠΓΕ Πλαγιές Αιγιαλείας) zone—one of the most distinctive and striking winegrowing areas in Greece. Established as a Protected Geographical Indication in 1997, the zone includes mountainous and semi-mountainous locations in Aigialia and Kalavryta, with vineyards often reaching elevations over 1,000 meters. This unique landscape, where steeply sloped vineyards seem to "hang" over the Gulf of Corinth, shapes a special mesoclimate marked by cool maritime influences and a distinctive viticultural identity. Part of the area is designated as Natura, thanks to the deep gorges, the rivers of the mountainous Peloponnese, and the biodiversity it supports.

The topography is defined by steep slopes, gorges, and varied orientations, creating a “mosaic” of different terroirs. Constant airflow blowing from the sea protects the grapes from diseases and favors the widespread use of organic farming. The slow, gradual ripening process results in grapes with remarkable freshness, high acidity, and rich aromatic expression.

The region's old vineyards are of particular interest, many of which are still trained in the traditional goblet (bush vine) shape and yield low quantities of high-quality grapes. Here, Roditis thrives in several distinct biotypes (natural clones), contributing depth and aging potential to the wines. These old vines are also used in ongoing clonal research projects aimed at better understanding the potential of varieties like Roditis and Mavrodaphne.

A new wave of winemakers is introducing modern techniques—such as extended lees aging, use of amphorae or concrete eggs, and gentle intervention—to highlight authenticity. The combination of tradition and innovation is clearly reflected in wines that express their origin with honesty and clarity.

If there’s one unifying element across all wines of the PGI Slopes of Aigialia (ΠΓΕ Πλαγιές Αιγιαλείας), it is freshness—both as a tasting profile and a mindset. The clarity, vibrancy, and intensity of the fruit provide a direct expression of place.

As part of a complete wine tourism experience, the region offers visits to historic wineries, vineyard walks with views over the sea, and tastings paired with local delicacies—a memorable escape where nature, culture, and excellent PGI (ΠΓΕ) wines come together.
