HSI – From hop harvest to the brewery
Hop Storage Index | When evaluating hop quality, many use the Hop Storage Index (HSI) as a simple analysis to get an indication of how much the hop has been aged. The rule of thumb is: the higher the HSI, the poorer the hop variety was harvested, stored, and processed. Although HSI can be a useful tool, it is important to understand that the value should not be the sole indicator to understand the total hop quality.
