1. A system for extraction of soluble flavoring components from a solid flavor carrier material into a brewing liquid, wherein the system comprises:
a process vessel arranged to receive the solid flavor carrier material and to receive and discharge brewing liquid material comprising the brewing liquid, wherein said process vessel comprises an inlet for the solid flavor carrier material, a circulation inlet for the brewing liquid material comprising the brewing liquid and a circulation outlet for the brewing liquid material comprising the brewing liquid, and
a filtration device for separation of solid components from the brewing liquid material comprising the brewing liquid, wherein said filtration device is a cross-flow filtration device comprising at least one cross-flow filter within the cross-flow filtration device, a circulation inlet for the brewing liquid material comprising the brewing liquid, a circulation outlet for unfiltered brewing liquid material comprising the brewing liquid and a closable outlet for filtered brewing liquid material comprising the brewing liquid;
wherein the process vessel and the filtration device are comprised in a recirculation loop for circulation of the brewing liquid material comprising the brewing liquid,
wherein the circulation outlet of the process vessel is connected to the circulation inlet of the filtration device in the recirculation loop,
wherein the circulation outlet of the filtration device is connected to the circulation inlet of the process vessel in the recirculation loop,
wherein the system further comprises a recirculation pump for generating a flow of the brewing liquid material comprising the brewing liquid in the recirculation loop,
wherein the recirculation loop further comprises a closable feed inlet for introduction of the brewing liquid material comprising the brewing liquid into the recirculation loop, said closable feed inlet being connected to the circulation inlet of the process vessel, and
wherein the recirculation loop optionally further comprises a closable drain outlet.
