At the BJCP beer judging competition, Dr Errol Cason won Best of Show with his Belgian Saison. Here he is presenting at the AfricaBrew2020 Brewing conference.

Staff and students from the University of the Free State (UFS) once again proved their skills in beer homebrewing when they walked away with one first place and two second places at the 13th annual Anheuser-Busch Inbev (AB-Inbev) – formally South African Breweries (SAB) – intervarsity beer brewing and tasting competition, and the Beer Judging Certification Programme (BJCP) competition held at the AfricaBrew2020 Brewing conference. Both these events took place over the weekend of 27 and 28 November 2020.

Evil Twin Double and Three Sips German 

Competing in the AB-Inbev/SAB Intervarsity brewing and tasting competition, was a group of students from the UFS Department of Microbial, Biochemical and Food Biotechnology, consisting of Eduvan Bischoff (PhD student), Elzette van der Walt (MSc student), Culien van der Merwe (MSc student), Gunther Staats (MSc student), and Twyne Skein (MSc student). This team came second in both the Indian Pale Ale (IPA) category with their Evil Twin Double IPA and in the Lager category with their Three Sips German Pils. 

“This is an outstanding accomplishment. Congratulations also go to our fellow Free Stater’s at the Central University of Technology (CUT) for winning the India Pale Ale (IPA) category as well as best overall beer with their New England IPA,” commented Dr Errol Cason, Senior Lecturer in the UFS Department of Animal Science, also representing the liquid yeast company LiquidCulture Yeast.

According to Dr Cason, this SAB-sponsored competition sees students from local universities brew and enter beers for judging, and competing for prizes, including the coveted ‘Best of Show’ trophy. 

“This event also aims to promote beer culture along with responsible drinking, by hosting talks by industry experts where students can interact with commercial brewers, scientists, and marketers,” says Dr Cason. 

The event was hosted by South African Breweries (SAB) and CUT, through the Centre for Applied Food Sustainability and Biotechnology (CAFSaB), in association with the UFS. 

Although the event was moved online in 2020 due to the international pandemic, it did not mean that there was a decline in the quality of presentations, or in the beer entered by universities. – D r Errol Cason

Dr Cason explains that entrants are usually challenged to brew beers according to the 2015 Beer Judge Certification Programme (BJCP) guidelines in lager, IPA, winter warmer, and fruit beer categories. 

“This year included the African Premium Ale and Lockdown Brew categories as well, where teams were mostly left to invent and experiment on their own with a few rules, such as using only indigenous African ingredients or ingredients that were available in supermarkets during lockdown,” says Dr Cason. 

There is also an award for the best bottle dress (label). 

Dr Cason believes that although the event was moved online in 2020 due to the international pandemic, it did not mean that there was a decline in the quality of presentations, or in the beer entered by universities. 

Belgian Saison and Extra Special Bitter

He and Christopher Rothmann, who is busy with a PhD in Biotechnology at the UFS and is co-founder of the company LiquidCulture (LC) Yeast, attended and presented at the AfricaBrew2020 Brewing conference. AfricaBrew is an annual brewing conference specialising in workshops and demonstrations for home and professional brewers. 

Accompanying the conference is a BJCP beer judging competition where all home and professional brewers can enter beers. During this competition, Dr Cason won Best of Show with his Belgian Saison. Rothmann came second with his Extra Special Bitter.

Since LiquidCulture Yeast was found in 2018, this commercial venture has since spun out and are now providing liquid brewing yeast to the homebrewing and commercial brewing industry. Rothmann and Dr Cason are also founding members of the Kovsie Brewery (along with Dr Jan-G Vermeulen and Eduan Hellmuth), which is currently being constructed on the UFS Paradys Experimental Farm facility.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
