Understanding temperature profiles of process water supplies plays an important role in evaluating the energy efficiency of distilleries producing Scotch Whisky and gin.
Chivas Brothers is the Scotch Whisky and premium gin
business of Pernod Ricard, the world's no.2 in wines and
spirits. Chivas Brothers' award-winning portfolio features
some of the world's most revered Scotch whisky brands including
Chivas Regal, Ballantine's, The Glenlivet and Royal Salute.
The portfolio also includes two of the world's leading English
gins, Beefeater and Plymouth gin, plus a selection of highly
acclaimed single malt whiskies, including Aberlour, Longmorn,
Scapa, Strathisla and Tormore.
Chivas Brothers wishes to gain a better understanding of
the temperature profile of its process water supplies, as
these play an important role in the energy efficiency of its
distilleries, which are some of the more efficient in the sector.
Process water is used to transfer heat from the mashing process to
the incoming water for the next batch. This can lead to
high water losses during periods when incoming
temperatures are too high. The business currently has no
information on the variability or range of incoming water
temperatures from different water source types and needs to
understand these better in order to assess the potential
impacts of climate change and inform future developments or
Water sources are monitored using Tinytag Aquatic 2 data
loggers, while Tinytag Plus 2 data
loggers are used to record air temperatures. 14
Aquatic 2 loggers are located within river water intakes and dams,
spring water collection cisterns and borehole water storage tanks.
The Speyside area is split into four regions, each of which has a
Plus 2 data logger to monitor ambient air temperatures, generally
housed in a shaded location out of direct sunlight.
All loggers are recording actual temperature every 20 minutes on
the same time-scales. The monitoring data will be used to
review the range and variability of temperatures of water supply
sources in response to local ambient air temperature and
analysed to establish a predictable relationship, if one exists.
The relationship information will be used to predict periods where
production may be affected by extreme temperatures to allow better
management. The data will also be used to assess the vulnerability
of sites to climate change in the future.
Tinytags were chosen because they are robust for use in
extreme environments, are self-sufficient
and have good battery life. Data can be easily
downloaded in the field and the units are easily transferable to
other locations, if required.
Dr. Ronald Daalmans, Environmental Sustainability Manager at
Chivas Brothers Ltd. has been impressed with the resilience
of the loggers in the outdoor environment, having used the
loggers previously for internal process assessments within its
distilleries. He comments, "The loggers are in use by
other stakeholders within the sector such as SEPA, Fishery Boards
& Trusts and Marine Scotland Fisheries Service, which means we
are generally confident of having comparable results, or have the
facility to cross-calibrate with others."
