OE, original extract (oP); RE, real extract (% w/w); ABV, alcohol by volume (%, v/v); Viscosity (mPa﹒s) RDF, real degree of fermentation (%); TC, total carbohydrate (g/L); NSPs, non-starch polysaccharides (mg/L); NSPs/TC, proportion of total NSP in total carbohydrate (%, w/w); BB, barley malt beers; WB, wheat beers. Values are mean ± standard deviation of three replications. Means represent average value ± standard deviation of all beer samples in the same category; different letters indicate significant difference among the average values of barley malt beers and wheat beers under the p < 0.05 level.
