The Taylor / Pretoria Conventions: The Research Workhorse

If you read the academic sorghum malting literature, you are mostly reading methods from J.R.N. Taylor's Pretoria lab and the researchers it trained — the field's de facto research conventions, built to answer research questions about sorghum's biochemistry rather than to evaluate malt for a brewery's purchase decision.

Part of the Evaluation Methods survey.

What it is​

Not a published standard but a body of practice: the assay choices, adaptations, and conventions running through decades of sorghum malting papers from the University of Pretoria and its wide academic lineage — beta-amylase characterization,1 modification and enzyme-development studies, and the synthesis reviews the whole field cites.2 This site cites that literature throughout, because for sorghum's underlying science it is the record.

What it's for — and not for​

These are research instruments: built to isolate variables, characterize mechanisms, and compare treatments. They answer "how does sorghum beta-amylase respond to germination temperature?" superbly. They were never meant to answer a maltster's or brewer's question — "should I buy this lot, and what beer will it make?" — and the academic emphasis on enzyme biochemistry reflects research priorities, not a claim that DP is what brewing needs. Borrowing research conventions as evaluation standards repeats the field's pattern: right tool, wrong question.

The verdict​

Indispensable for science; not an evaluation standard, and never claimed to be. The gap between research instruments and a working evaluation standard is precisely the space the GFB-SME proposal addresses — and the kiln schedule this site publishes was itself developed with guidance from this tradition, so the respect here is earned, not diplomatic.
