Untargeted metabolomic profiling of 100% malt beers versus those containing barley adjunct (2024)
Journal Article

Why was the work done: The incorporation of unmalted barley at high proportion in the grist can introduce unfavourable bitter and astringent characteristics to beer, resulting in an upper limit on the proportion used. The flavour active compounds fro... Read More about Untargeted metabolomic profiling of 100% malt beers versus those containing barley adjunct.

Development of an open-source carbon footprint calculator of the UK craft brewing value chain (2023)
Journal Article

Craft breweries may fall behind large brewing companies in reducing the carbon footprints of their value chains due to limited resources, financial constraints, and a lack of technical knowledge to fully understand their emissions. However, by increa... Read More about Development of an open-source carbon footprint calculator of the UK craft brewing value chain.

Bayesian and ultrasonic sensor aided multi-objective optimisation for sustainable clean-in-place processes (2023)
Journal Article

In food and drink manufacturing, clean-in-place procedures are essential for hygienic and efficient operations but often over-clean process equipment leading to unnecessary use of energy, water, and chemicals. Previous attempts in the literature to o... Read More about Bayesian and ultrasonic sensor aided multi-objective optimisation for sustainable clean-in-place processes.

Impacts of Adjunct Incorporation on Flavor Stability Metrics at Early Stages of Beer Production (2021)
Journal Article

The fresh flavor of a beer brand is one of its most important quality parameters and should be retained as long as possible through shelf-life. Early stages of beer production can have significant impacts on beer flavor stability. The use of cereal a...

A TCATA by modality approach to study the multisensory temporal profile of hop bitter and flavour products applied in lager (2021)
Journal Article

Previous research suggested that iso-alpha-acids and hulupones add different bitterness profiles to beer and hop-derived volatiles modify temporal dimensions of bitterness qualities via cross-modal interactions. This research aimed to understand the... Read More about A TCATA by modality approach to study the multisensory temporal profile of hop bitter and flavour products applied in lager.

Exploring the multisensory perception of terpene alcohol and sesquiterpene rich hop extracts in lager style beer (2021)
Journal Article

Understanding the contribution of hop essential oil to the multisensory profile of beer is known to be challenging because of its chemical and sensory complexity. Limited research has been conducted investigating hop-derived volatiles' role in the mo...

The influence of yeast strain on the oxidative stability of beer (2021)
Journal Article

Flavour stability, or instability, relates to the rate of flavour change through shelf-life of packaged beer. There are several control points in the production of beer where flavour stability may be altered. These include fermentation and the influe...

Green Malt for a Green Future – Feasibility and Challenges of Brewing Using Freshly Germinated (Unkilned) Malt: A Review (2021)
Journal Article

In malting, the kilning step is by far the dominant user of energy and has thus become the main target in reducing the carbon footprint of malting operations. Brewing beer using ‘green’ (germinated, but not dried) malt, thus saving the substantial en...

On the contribution of malt quality and the malting process to the formation of beer staling aldehydes: a review (2021)
Journal Article

Despite decades of extensive research, beer flavour instability remains a challenge for both brewing and malting industries. Malt impacts the brewing process as well as the quality of the final beer. It also affects the stability of beer flavour, as... Read More about On the contribution of malt quality and the malting process to the formation of beer staling aldehydes: a review.

Brewing with 100% green malt – process development and key quality indicators (2020)
Journal Article

Brewing with undried, germinated (green) malt has the potential to lower energy and water usage in the malting and brewing chain. However, doing so introduces technical and biochemical (flavour) challenges. Beers were brewed using 100% green malt (n...
