I went to some lengths to explain the difference between naturally occurring germination and the controlled germination which is part of the malting process. Germination, and the resulting conversion of starches to sugars, happens without the malting process. The malting process can’t happen without germination. Germination, and the related chemical reactions, can be controlled but will happen spontaneously when the relative humidity is at, or near 100%, and the temp is above freezing (warmer is better, as in faster, but it will still occur at cool temps; if it didn’t we couldn’t grow cereals at the northern latitudes where many cereals are commonly grown). The malting varieties of barley which are commonly grown are “predisposed”, so to speak, to germinate readily when the appropriate conditions exist. This makes growing those varieties challenging for the grower. One late rain, just before harvest, when ambient temps are relatively high, can result in the grain spouting in the head, rendering the crop useless for malting. Once germination occurs, and the enzymes are available to the endosperm, conversion will begin.
It’s worth remembering that germination and it’s cousin, spontaneous fermentation, were discovered, not invented, thousands of years ago. Those discoveries led to the development of fermented beverages, a process which continues to be refined all these years later. Science, or, more appropriately, good science, never sleeps. Good scientists don’t proclaim “…from where the sun now stands we will never study (insert topic here) again. We know all there is to know”. The sciences of brewing, cereal chemistry, and plant breeding can collaborate to develop varities of cereals which are specfically adapted to enhance the malting process. But, the science can’t, at least at this point, “create” enzymes during the malting process.
All of which is a way of taking a long road to get to the small house of “it’s a matter of semantics”.
