Posamas

About Posamas

Posamas is a Turkish circular-economy food technology company focused on upcycling grape side-streams into multifunctional ingredients. Built around the Kalecik Karası grape variety and rooted in vineyard-based experience, the company develops ingredients from grape pomace and related by-products for use in cosmetics, functional foods, and soil-health applications.

The company positions itself at the intersection of science, terroir, and regeneration. Its model is designed to turn local agricultural residues into higher-value materials while supporting local growers, reducing waste, and extending the life cycle of vineyard resources.

Core Values

• Circularity: The company’s core model is to upcycle grape side-streams rather than discard them, turning pomace into ingredients and returning residual biomass to the soil.
• Sustainability: Posamas emphasizes waste reduction, methane prevention, and regenerative use of local agricultural resources as part of its circular bioeconomy approach.
• Local terroir and traceability: The company is closely tied to Kalecik Karası grapes and local vineyard ecosystems, highlighting the value of regional varieties and place-based production.
• Women-led entrepreneurship and inclusion: Posamas presents itself as a women-led venture and says it aims to create opportunities for women across agriculture, R&D, product design, and leadership.
• Science-backed innovation: The company frames its work as combining research, product development, and regenerative practices to create multifunctional ingredients and soil-support solutions.

Unique Aspects

• Built around Kalecik Karası grapes: Posamas centers its ingredient platform on a local Turkish grape variety, using its pomace and seed fractions as the raw material base.
• Closed-loop vineyard model: The company says it returns extracted pomace back to the soil as a natural amendment, creating a vineyard-to-product-to-soil cycle.
• Cosmetics and soil-health linkage: Unlike a single-use ingredient supplier, Posamas connects cosmetic ingredient production with soil microbiome and regenerative agriculture initiatives.
• Women-led founding story: The company highlights a founder-led, women-driven entrepreneurship journey rooted in vineyard experience and supported by local growers and cooperatives.
