What happens to hop pellets during unexpected warm phases?
Today, production and storage of hop products largely take place under defined conditions. Special care is taken that negative influences - such as the presence of oxygen and high temperatures - on the quality are kept to a minimum. Comprehensive documentation on this topic is available (1). On the other hand, there is still little or no interest - as regards transport conditions. Temperature records during long-lasting transportation to Asian and South American countries, however, give rise to further, more intensive investigation.
The problem of excessive temperatures, to which hop pellets are sometimes exposed, has already been discussed in a previous paper (2). These results can be supplemented by the following observations and investigations."
