Reed or vineyard site in the municipality of Spielfeld-Obegg in the Austrian wine-growing region of southern Styria, named after the cadastral municipality. The area is divided into the two Subrieden Obegg and Obeggberg. Another common name for the latter is "Schneckenkogler" (Kogl = mountain), because in former times countless small snail shells were found in the vineyards. The southeast-facing and in part extremely steep slopes with 145 hectares of vineyards are located at an altitude of around 370 metres above sea level. The eastern area is dominated by sandy soil with a depth of around one metre, while limestone with water-bearing layers attested by old wells dominates the rest of the area. The forest is very close to the vineyards, so the vines are raised to protect them from damage by game. Especially the white wine varieties Sauvignon Blanc, Morillon, Chardonnay and Welschriesling are cultivated here. A part is planted with the Altsteirischer Mischsatz. Shares in the vineyards are held, for example, by the vineyards Polz Erich and Walter, Skoff Walter, Teschl Ferdinand and Trummer Josef.
