Enzyme Temperature Explorer

Drag the mash temperature and watch the three jobs that share the kettle.

The three jobs are sorghum starch opening, the heat-tolerant liquefaction enzyme working, and the conversion and finishing enzymes living and dying. It answers why no single temperature serves all three, which is why the Reliable Mash runs three temperatures on purpose. The ranges are the site's published figures; the explorer illustrates the problem and does not model measured enzyme kinetics.

• Sorghum starchclosed — enzymes can't reach it
• Liquefaction enzyme (heat-tolerant alpha)working — chosen to survive heat other enzymes cannot
• Conversion & finishing enzymesaround their working conditions (added at 145 °F)

Conversion enzymes are in range — but sorghum starch is still closed. Enzymes can't convert starch they can't reach. (A barley mash works here. This one doesn't.)

That is why The Reliable Mash stages: open hot (190 °F), then cool to convert (145 °F), then mash out (180 °F) — three temperatures because three jobs.
