IPA: /ʌnˈmɔːltɪd/
KK: /ʌnˈmɔltɪd/
Describing grain that has not undergone the malting process, meaning it has not been germinated or converted into malt.
The recipe calls for unmalted barley to create a different flavor profile in the beer.
Unmalted → It is formed from "un-" (meaning not) and "malted" (from Old English "malt", meaning to convert grain into malt). The word "unmalted" means not converted into malt, referring to grains that have not undergone the malting process.
Think of 'not' ('un-') having gone through the process of converting grain into malt — that's why unmalted refers to grains that haven't been malted.
