Direct practical support for ZET-187. The nearby classification of a lactic-acid bacterium as yeast is erroneous; this does not invalidate the comparison-design example.

Richardson uses a pepper-only comparison to explain the benefit of a consistent inoculum (257–258), and recommends recording weights, temperatures, times and gravity measurements (248,279).
