Optimisation of alkaline reagent based chemical pre-treatment of Brewers spent grains for bioethanol production (2014)
Journal Article
Wilkinson, S., Smart, K. A., & Cook, D. J. (2014). Optimisation of alkaline reagent based chemical pre-treatment of Brewers spent grains for bioethanol production. Industrial Crops and Products, 62, 219-227. https://doi.org/10.1016/j.indcrop.2014.08.036

The pre-treatment step of lignocellulosic ethanol production is recognised as the most energy intensive part of the overall process. Key objectives are thus that pre-treatments should operate effectively at low to moderate temperatures and at high pe...

Premature yeast flocculation (PYF) is a sporadic condition of brewery fermentations in which yeast settles out from the fermenting wort earlier or more heavily than usual and before full attenuation has been reached. Factors originating from malt (i....

Origins of the perceived nutty character of new-make malt whisky spirit (2013)
Journal Article
Boothroyd, E., Linforth, R. S., Jack, F., & Cook, D. J. (2014). Origins of the perceived nutty character of new-make malt whisky spirit. Journal of the Institute of Brewing, 120(1), 16-22. https://doi.org/10.1002/jib.103

New-make malt spirits were sourced from 35 individual Scotch Whisky distilleries and their sensory characteristics rated by a trained panel using descriptive analysis. Selected samples (either high or low in perceived nutty character) were analysed u... Read More about Origins of the perceived nutty character of new-make malt whisky spirit.

Flavour generation during commercial barley and malt roasting operations: A time course study (2013)
Journal Article

The roasting of barley and malt products generates colour and flavour, controlled principally by the time course of product temperature and moisture content. Samples were taken throughout the industrial manufacture of three classes of roasted product...
