The traceability of the wood and hoops is controlled throughout the process and all stages undergone by each barrel are recorded. All of this information is identified by a code on a small label that is adhered to the penultimate hoop of the barrel. This ensures the traceability of each barrel from the start of the process until it reaches the end customer.
The quality control tests conducted throughout the production process guarantee Murúa barrels. This is confirmed by the custom enjoyed by Tonelería Murúa for decades.
Tonelería Murúa has a Quality and Environmental Management System in place, certified in accordance with ISO 9001 and ISO 14001 since 2002.
