Olmeda Orígenes Fish. From our Mediterranean and Cantabrian Seas to our Atlantic Ocean, Spain is surrounded by fish banks that have been an important part of our diet for millennia. These are nutritious species caught respecting environmental regulations and the ecosystem of our seas, and are packed manually one by one to guarantee the best appearance and flavour. Take a fillet of our fish and bring it to your mouth to discover an explosion of flavours perfectly balanced with the seasoning and the salty taste of the sea.
