The present application relates to methods for producing beverages with low levels of acids, cations and/or sugars. The methods comprise the step of removing acidic ions through an AX-REED membrane stack and optionally removing cations through a CX-REED membrane stack. In certain embodiments, the AX-REED and the CX-REEF membrane stacks are operated in parallel. The methods may also comprise a step of converting sugar to organic acid, while simultaneously removing the generated organic acid through the AX-REED membrane stack. The sugar may for example be converted with the aid of enzymes and/or microorganisms.
