摘要：
The present invention relates to a process of manufacturing a liquid alcoholic beer concentrate, said process comprising:
providing a low alcohol beer having an ethanol content of 0-1% ABV, a free amino nitrogen content of 8-400 mg/L and containing 0.1-4 g/L maltotriose and 0.5-6 g/L of maltotetraose;
removing at least 70 wt. % of the water present in the low alcohol beer by means of membrane separation to produce a low alcohol beer concentrate, wherein the membrane separation is selected from nanofiltration, reverse osmosis and forward osmosis;
combining the low alcohol beer concentrate with alcoholic liquid having an ethanol content of at least 30 wt. % to produce a liquid alcoholic beer concentrate having a an ethanol content of 10-60 wt. %.
The present process offers the advantage that it is relatively easy to operate, whilst at the same time losses of small organic molecules (e.g. acids) are minimized effectively.
