The rapid evolution of the Internet of Things (IoT) has given rise to the Industrial Internet of Things (IIoT) otherwise known as the 4th Industrial Revolution. Embracing IIoT in the brewing industry, also known as Brewing 4.0, promises revolutionary advancements in brewery operations. Breweries like Ab InBev and Sugar Creek are advanced levels of implementation of IIoT. The implementation of which has decreased process losses and improved performance efficiency. However, the technology is not without its own challenges e.g., the lack of uniform standardization, security concerns and high energy requirements among other key issues discussed. There are also concerns of interoperability of devices deployed in IIoT to overcome Industrial, Scientific and Medical (ISM) band congestion. This paper delves into the enabling technologies for IIoT implementation in brewing, such as IoT, blockchain, cloud computing, and Artificial Intelligence. The paper also addresses the multifaceted challenges involved in IIoT adoption and proposes innovative risk mitigation strategies.
