The Toasting

In recent years the J. M. Gonçalves has invested a lot of its resources in research and development of its kinds of sandwiches and its embodiment. Combining the latest technology with our coopers Savoir Fairedos masters, our firings are homogeneous and consistent, always being used only oak wood during the process.

To ensure consistency and reproducibility, J.M. Gonçalves has a modern System Supervision and Control of Heat Treatment:

  • Monitoring the binomial time-temperature;
  • Screen comprehensive control;
  • Individual monitoring of each "hot flush"
  • 8 barrels monitored simultaneously;
  • Individual record of the history of each barrel in the database.


The revalidation of the effectiveness of this system is carried out by methods of measurement, sampling, depth of toast according to quality parameters.
