Fig. 1. Comparison of beers that carbonated vs. those that did not. The indicated data from Table 2 and Supplemental Table 1 were averaged for the 16 beers that carbonated by bottle conditioning and the three that did not. The pH, mostly due to the high concentration of lactic acid, represents the largest difference between the carbonated and non-carbonated beers. The plotted values are the means, and the error bars are the standard deviations. *p < 0.05, **p < 0.01
