LSTM Networks for Dynamic Prediction
The paper introduces Long Short-Term Memory (LSTM) networks as a data-driven approach to model beer fermentation dynamics. Unlike traditional kinetic models, LSTMs can capture complex, non-linear temporal dependencies across diverse fermentation conditions. This robust AI architecture provides accurate, real-time predictions of key variables like apparent extract and pH, crucial for modern brewery operations.
Leveraging Real-World Fermentation Data
A critical strength of this research is its use of a large, heterogeneous dataset comprising 1305 real-world fermentations (ales, IPAs, lagers, mixed-culture beers). The data, including apparent extract, temperature, and pH, underwent meticulous preprocessing and noise augmentation. This extensive training allows the LSTM model to generalize effectively across varied beer styles and operating conditions, surpassing the limitations of recipe-specific models.
Enhancing Brewery Monitoring and Control
The LSTM plant model offers practical benefits for breweries, enabling short-horizon forecasting of attenuation and pH (via soft sensing), and anomaly detection during fermentation. With further development, it could also be embedded within a model predictive control framework, allowing breweries to explore alternative temperature schedules and assess their likely impact on fermentation trajectories “in silico” before committing to process changes, leading to improved process changes and product quality.

Mastering Complex Mixed-Culture Fermentations
The LSTM model demonstrated exceptional performance in mixed-culture fermentations, yielding the smallest apparent extract errors (RMSE 0.228 °P, MAE 0.128 °P). This is particularly significant as mixed-culture fermentations involve intricate interactions among multiple yeast species, which are notoriously challenging for traditional models. The model's success here highlights its ability to learn and predict complex biological processes, providing a powerful tool for breweries exploring novel flavour profiles and more diverse product lines. This capability is key for the modern craft sector.
