Carlsberg exports beer to many different countries, which means transport in varying climatic conditions. The quality of the beer can be impaired if exposed to high temperatures for a long time. In the worst case, it can even go bad.
It is possible to use temperature controlled containers, but as they increase transport costs this should be avoided whenever possible. Temperatures below zero degrees can also ruin the beer. In addition, certain beers are transported in cartons which can be weakened if the humidity is too high.
High and low temperatures can ruin the beer
In order to provide Carlsberg with a good basis for deciding when transport should take place with temperature controlled containers, or even when to avoid transport to a certain region, SMHI is preparing relevant climate statistics.
– It is very important for us as a beer producer to be sure that our deliveries are of the highest quality and in no way in risk of ruining the beer. SMHI's climate statistics help us avoid certain weather conditions that have a negative impact on the beer, such as excessive heat and freezing conditions, says Christian Rosengren, Commercial Manager - DraughtMaster, Carlsberg.
Continued work with SMHI's climate statistics for transports
SMHI has produced world maps showing how many hours each month and year that the temperature normally exceeds 35 ° C in different parts of the world. Similarly, periods with temperatures below 5 ° C and relative humidity above 80 percent are presented.
–The world maps were just a first step. With these as a basis, Carlsberg has made decisions about which regions they want to look more closely at. For those locations, we have produced data that shows variations over the day and year. The first step with the world maps was to help them see in which areas there is a risk for climate problems in general. In the second step, they have received specific data for the selected sites, which they can then use to simulate the temperature and humidity conditions for the beer and test how the quality is affected. Based on simulations, Carlsberg can determine when and where they need to use temperature controlled containers and if there are areas where it is best to avoid transport at certain times of the year, says Magnus Asp, project manager, SMHI.
– We also have discussed producing climate statistics for specific transport routes. Another development opportunity is to produce corresponding statistics for future climate. But first, the results of current climate statistics will be evaluated, concludes Magnus Asp, project manager, SMHI.
