8. Round Table Cocoa Hamburg
A quality vision for the future
Sponsored by the German cocoa and chocolate foundation

With more than 100 participants the Round Table Cocoa Hamburg has once more been a great success. Innovations such as the internationalization of the presentations and the provision of simultaneous translation further increased the quality of the program. Through the introduction of a new presentation format - the spotlight talks - additional important topics could be addressed. Core of the Round Table has been as always the exchange between research and industry. For the numerous contributions to the discussion, that have made this exchange and the success of the Round Table possible, we would like to thank all participants very much.

We are happy to welcome you at the 9th Round Table Cocoa Hamburg from 3-4 June 2021.


Key topics

Representatives from leading universities are speaking in 2019 about current research topics. This years key topics are cocoa bean quality, post-harvest treatment and planting systems for the future.

Cocoa bean quality

  • Off-flavors in cocoa and chocolate
  • Taste- and aroma-active substance based quality evaluation
  • The development of an international standard for cocoa sensory evaluation
  • Strategies to minimize cadmium contamination
  • Impact of transportation conditions

Primary post-harvest processing

  • Taste and aroma-based steering of the fermentation process
  • Impact of drying on taste and aroma attributes Einfluss des Trocknungsprotokolls auf das sensorische Profil
  • Off-flavor development during fermentation and drying

Planting systems for the future

  • Cocoa cultivation and climate change: immediate, intermediate and long term solutions
  • Impact of climate change on cocoa bean quality
  • CSSV, BP, FP and WB: strategies towards a multiple disease tolerance
  • Cocoa genetic diversity: taste- and aroma-focused breeding approaches

A Quality Vision for the Future


farewell and end of the event


The Round Table Cocoa is a "must attend" for the cocoa research world. The mix of world class speakers, presentation of new research, and discussions on relevant topics in an attractive city make this event extremely worthwhile.Martin Gilmour

The Round Table Cocoa provides an excellent venue where all levels of the chocolate industry and research can interact. It allowed me the opportunity to engage and interact with European stakeholders, share research results and realize future research needs.Lyndel Meinhardt
From a local platform on cocoa-related crop biology the Round Table Cocoa Hamburg has developed into a national and now international forum on interdisciplinary cocoa research. State-of-the-Art specialist lectures and global network contacts make this congress indispensable for cocoa experts.Dr. Rodger Wegner
WGA Hamburg
The Round Table Cocoa Hamburg is a great quality conference which provides the opportunity to connect and network. The possibilities to learn and interact during the coffee and lunch breaks, poster sessions and the 2 social evenings made it a well worth while event to attend. Brigitte Laliberté
Bioversity international
The Round Table Cocoa is a very important pillar on the cocoa agenda. It provides an excellent overview on recent research questions and innovative approaches, and enables intensive network building between research and industry through fruitful exchange and discussion. It is an absolute must for everybody working in the cocoa sector.Susanne Miescher-Schwenninger
The Round Table Cocoa is a unique opportunity to: build networks with actors from cocoa industry and research; get informed about interesting ongoing cocoa research projects; discuss current challenges regarding cocoa bean quaility Corinna Schoppe
For me the Round Table Cocoa has been once again one of the best opportunities to discuss news and recent challenges of the cocoa supply chain and develop strategies to meet those challenges. Besides high quality talks and insights, network building with the international participants is the best answer to our questions arising from the daily work with cocoa. Hauke Will
