<p><i>Panel A</i>: Sampling regime employed representing 3 years of ACA fermentation. White bars represent the span of sampling times for each batch. Labels indicate batch number (number of barrel replicates in parenthesis). <i>Panels B/C</i>: Real-time PCR of total bacteria and total yeast populations (<i>Panel B</i>) and pH and °Plato (<i>Panel C</i>) across ACA fermentation. All values are averages of multiple batches tested in duplicate (where possible; <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0035507#pone.0035507.s001" target="_blank">Figure S1</a>). Error bars indicate ±1 standard deviation. ◊, Total bacteria; □, total yeasts; ▵, pH; ○, °Plato. Arrow indicates time at which fruit was added and beer was refermented in bottle.</p
