AWRI Residency Week 3

Week 3 at the AWRI has only increased my interests in the yeasts – I found out about the fascinating ‘Shipwreck yeast’ as it is casually called. As I understand it there is a shipwreck in the Bass Strait out of which some old beer bottles were unearthed. The staff at the AWRI were able to isolate 220 year old yeasts from one of these bottles and then partnered with James Squire to produce a beer.  The story is told much better by many more people, here are a few links.

I have also been doing some more detailed reading about the birth and bud scars of yeasts. The drawing above is my impression of the budding yeast Saccharomyces cerevisiae (the variety that produces bread, beer, and wine). I drew it because I am unsure if I am allowed to reproduce other images I found.

I also found this quite delightful description of the separation of the budding yeast cells, it is an older publication but it is the most poetic description I have found. I find it easy to anthropomorphize this.

“Before separation the rims of the two scars of both cells are believed to lie in contact, strengthening the bond between cells. When, however, the cytoplasmic connection is lost, the independent increase in volume of the daughter cell results in a stretching of its birth scar; the shearing action between the two scars then causes the mechanical connection to break.”

AWRI Residency Week 2

Through some casual conversations with the staff at AWRI, and also through mining the library on site, I have found some new tangents to pursue outside the core sensory project. I was completely seduced by a book (the cover of a book) that categorises hundreds of yeast with images, descriptions, colours, and lists of the places they have been found. It turns out yeasts are hosted in the oddest places… and so I began documenting the yeasts that had some of the more poetic and absurd assortment of hosts. Here are just a few

Lodderomyces elongisporus has been found in:

Brewery in Denmark, soil in South Africa, fruit syrup in Germany, orange-syrup base for soft drink, concentrated orange juice and baby cream in the Netherlands, finger nail in Finland, concentrated orange juice in USA.

 Dipodacus ingens which has been found in:

Wine cellars, industrial waste.

Or the Debaryomyces etchellsii, found in:

Fermenting cucumbers and fruit fly in USA, tinned butter in India, faeces of human being in Brazil.

 

I am struck by how these yeasts are hosted by such varied sites of living and non-living, natural and processed bodies.

Yeasts don’t all reproduce the same, but there is a group of them (including the ones that assist in the creation of bread, wine, and beer) that produce a daughter cell as a bulbous bud growing off the side of its body – like a pregnant belly. When the daughter cell breaks off it retains a ‘birth scar’ (just as we have a belly-button). ‘bud scars’ on the other hand are present on the parent every time they then produce a daughter. I thought this was fascinating, and potentially quite unique, because I couldn’t think of an insect, animal or human that showed on it’s skin how many children it had given birth to.

“Bud scars, when viewed from the outside of the wall, show a circular brim, slightly raised above the cell surface. The brim surrounds a slightly sunken area, which shows a concentric pattern around a small central depression.”

Thank you to Simon for sharing his knowledge on yeasts.

AWRI Residency Week 1

My project proposal for working with the Australian Wine Research Institute stemmed from ten years of working with food as art material, but more specifically, my last five years of dabbling in cross-modal processing research. In my own very casual terms, cross-modal research addresses how the different senses cross-pollinate one another to affect perception and experience. For example, how does seeing the colour green affect the perceived flavour of beer?

My investigations into this field began during a short placement in the experimental psychology lab of Professor Charles Spence at Oxford in 2012, and have been maintained through consistent personal research and reading. I have formalised these ideas within my own practice primarily through my concept meals (link) in which I design new plates, cups, cutlery etc to reimagine the choreography of dining. The logic of cross-modal research is built into the designs I create; colour, shape, texture, and weight are manipulated in order to achieve a specific experience (often on a subconscious level).

Beyond the seed of research and development my practice-based experiments have so far been entirely unscientific. Having the opportunity to work with the sensory team at AWRI offers expansive collaborative opportunities towards the production of a new body of work, and hopefully new insights into the field. I am creating artwork on site at the AWRI that seeks to find a synesthetic harmony between the flavour of wines and 2D still or moving images. The goal is to consider how the intangible multi-sensory language of taste might be translated into visual forms. This creative output will have its foundation in scientific methods but will be translated through the creative process.

My first week at AWRI has been exciting, and has included a healthy dose of wine-tasting. Mostly though I have been overwhelmed by support and enthusiasm from the institute. My heartfelt thanks to all the staff at the institute for their generous welcome, and especially to the sensory team who will be hosting me for three months in 2019 (and who cleared me a desk space), Leigh Francis, Wes Pearson, Elanor Bilogevic, Damian Epinase Nandorfy, and Desiree Likos.
