How do Dolium kegs compare to traditional stainless steel kegs?

Dolium kegs offer significant advantages over traditional stainless steel kegs: zero upfront capital investment (traditional kegs require €30-60 per unit), no cleaning costs (saving 3-5L of water and chemicals per keg), 40% lighter weight for reduced shipping costs, no return logistics needed, and zero keg loss or theft risk. Dolium kegs maintain the same compatibility with all standard filling and dispense systems (A, G, S, D spears) while limiting CO₂ loss to less than 5% after 6 months and providing active oxygen barrier protection.
