What is kulbach value?
The ratio of the content of total soluble nitrogen to the content of total nitrogen in malt is called kulbach value, also known as protein solubility, expressed as percentage.
Kulbach value = total soluble nitrogen content in wort / total nitrogen content in malt × 100%
Kulbach value is a main index to check the solubility of malt, focusing on the activity of proteolytic enzyme of malt. The kulbach value of malt with good solubility is more than 40%, 45% is malt over dissolution, and less than 38% is poor dissolution.
