10 years
“We are excited to be celebrating 10 years in one of
the world’s leading wine research facilities.”
The Wine Research Centre at the University of
British Columbia celebrates its 10-year anniversary
in 2009. Much has happened since July 1999 when
I first arrived at UBC with four of my Ph.D. students
to establish the WRC in the Faculty of Land and Food
Systems (LFS).
As pioneers, the WRC has attracted scientists from
leading research institutions around the world.
Using a systems biology approach (transcriptomics,
proteomics and metabolomics), WRC scientists study
both fundamental and applied aspects of grapevines
and wine yeasts.
Our first decade has been remarkable. Today, the WRC
has three full time faculty members, four associate
faculty members, five research associates, one post
doc, six research technicians, four Ph.D. students and
five M.Sc. students. We have one of the most modern
and best-equipped viticulture and enology research
facilities in the world, thanks to financial support from
UBC, Western Economic Diversification, the British
Columbia Knowledge Development Fund and the
Canadian Foundation for Innovation.
Our research has generated five international
patents and 40 cutting-edge scientific papers.
Graduate students trained at the WRC now enjoy
careers as winemakers, lead researchers with private
companies and professors at both national and
international universities.
Over the past 10 years, Drs. Steven Lund, Vivien
Measday, Joerg Bohlmann and I have raised close to
$17 million in research funding, including three major
awards from Genome British Columbia and Genome
Canada. We have attracted leading researchers from
around the world; and eight M.Sc. and five Ph.D.
students have completed their studies in the WRC.
We look forward to many more successes given our
unique combination of talent and facilities.
We are delighted that our facilities can also provide
services to other scientists. For example, the WRC
microarray facility functions as a core facility for
the entire UBC research community and the mass
spectrometry laboratory serves LFS faculty and students.
This experience has been tremendously exciting and
rewarding. I wish to thank former LFS Dean Moura
Quayle and LFS Dean Murray Isman for their kind
support in our establishment and growth. I also wish
to thank all of our funding bodies listed in this 10 Year
Anniversary Report. Without your generous support,
these major achievements would not have been possible.
I also wish to express my heartfelt appreciation to all
the B.C. wineries that have donated wines to the WRC
Wine Library to be included in our wine-aging study.
As well, many private donors have given us rare and
outstanding wines that we use as control wines in our
analyses. Thank you also to donors who have made
financial contributions to the WRC. It is heartwarming
to receive such great support from the community.

what we do
enology research | van vuuren lab
Applied Research
A major goal of the van Vuuren laboratory is to help wineries improve wine quality through innovative and
leading-edge applied research. To date, significant milestones include:
½½ elucidated the metabolic adaptation of wine yeast to osmotic stress in grape must using sophisticated DNA microarray technology
½½ characterized the impact of yeast strain on the production of acetic acid, glycerol, and the sensory attributes of icewine
½½ established the impact of nitrogen additions to fermenting grape must on yeast metabolism and the production of flavour compounds in wine
½½ development of a yeast that produces more flavourful white wines (patented)
½½ development of the first prototype yeast strain that produces dry wine with reduced levels of alcohol (patent pending)
½½ development of the first prototype yeast strain
that produces increased levels of alcohol
(patent pending)
Enhanced Wine Yeasts
One of Dr. van Vuuren’s major achievements has been
to construct the world’s first two genetically enhanced
wine yeasts: S. cerevisiae ML01 and urea-degrading
red wine yeasts. Both yeasts have been patented and
approved for commercial winemaking by the U.S.
Food and Drug Administration, Health Canada and
Environment Canada.
Saccharomyces cerevisiae ML01
S. cerevisiae ML01 is the first genetically enhanced
wine yeast to be commercialized by the wine
industry in North America. Malolactic wine yeast
degrades malic acid to lactic acid during the alcoholic
fermentation. By doing so, it prevents spoilage of
wines by other microorganisms. The malolactic yeast
also prevents or limits the formation of bioamines
Hennie j.j. van Vuuren
Hennie J.J. van Vuuren, Ph.D., is the Director of the Wine Research Centre and
Associate Dean of Research in the Faculty of Land and Food Systems. The Blythe
and Violet Eagles Chair in Food Biotechnology was awarded to Dr. van Vuuren
whose previous position was the Senior NSE RC/Industrial Research Chair in
the Cool Climate Oenology and Viticulture Institute at Brock University. Before
immigrating to Canada, he was Professor and Chair of the Dept. of Microbiology
and Director of the Institute for Biotechnology at the University of Stellenbosch
in South Africa. Dr. van Vuuren is a wine biotechnologist and founding Director
of the WRC at UBC.

(allergens) by malolactic bacteria in wine. Scientists
have estimated that 30 per cent of the world’s
population cannot consume wine since they are
sensitive to bioamines.
Urea-degrading wine yeasts
Researchers in the van Vuuren laboratory have
constructed novel urea-degrading wine yeasts that
significantly limit the formation of ethyl carbamate
(urethane) in wines and brandy. Ethyl carbamate
is a naturally occurring compound found in many
fermented foods and beverages that may be harmful
to humans. In 2004, the U.S. National Toxicology
Program released a report based on an extensive
study that linked ethyl carbamate to increased rates
of various cancers, including liver, lung, ovarian and
skin cancer, in both female and male mice. Use of the
urea-degrading yeasts will limit the production of ethyl
carbamate by up to 92 per cent.
Fundamental Research
Yeast fermentation is a critical stage in the
winemaking process that converts the grape’s
sugars into alcohol and flavour compounds. To help
winemakers produce superior wines, fundamental
research in the van Vuuren laboratory focuses on
characterizing the stress response in yeast during
wine fermentations.
Laboratory strains of the budding yeast S. cerevisiae
have been used as a model eukaryote (cell with
a nucleus) for many years, and researchers have
accumulated a vast amount of information on the
genetics and physiology of this yeast.
More recently, investigators have employed highthroughput technologies to study global regulatory
and metabolic circuits in this yeast. However,
laboratory media and growth conditions are vastly
different from those that wine yeast strains encounter
during industrial wine fermentations.
The adaptation of wine yeast to the harsh conditions
during the fermentation of grape must has not been
well studied. To investigate how industrial wine yeast
strains of S. cerevisiae respond adaptively to longterm environmental stresses during fermentation of
grape must, researchers in the van Vuuren laboratory
profiled the yeast transcriptome throughout wine
fermentation.

Jenny Bryan, Ph.D. is an Assistant Professor at the University of British Columbia, with a joint
appointment in the Dept. of Statistics and the Michael Smith Laboratories. Dr. Bryan is also
a member of UBiC, UBC’s Bioinformatics Centre. Dr. Bryan joined the UBC faculty in 2001,
shortly after receiving a Ph.D. in Biostatistics from the University of California, Berkeley, under
the guidance of Professor Mark van der Laan. A native of Atlanta, Georgia, she graduated from
Yale University in 1992 with a double major in German and Economics. After that, Dr. Bryan
worked for the Boston Consulting Group before realizing her true calling in biostatistics.

Based on clustering and rigorous statistical criteria
done by Dr. Jenny Bryan, we have identified 62
novel Fermentation Stress Response (FSR) genes.
The biological functions of 62 of the FSR genes are
unknown and may play as-yet undetermined roles in
the long-term adaptation of yeast to an environment
in which ethanol is both a stressor and a carbon
source. This research is being led by Drs. Zongli Luo
and Christopher Walkey.
A systems biology approach (transcriptomics,
proteomics and metabolomics) is being used to
elucidate function of the 62 orphan genes. Proteomics
assays are being done at the University of Victoria
Genome BC Proteomics Centre in collaboration with
Dr. Christoph Borchers. This research is supported by
large-scale Genome BC and Genome Canada grants.
The PAU gene family is the largest multigene family
in S. cerevisiae; this family has 24 members and
is mostly located in the subtelomeric region of
chromosomes. Functions for the PAU genes have
not been established, but several of these genes
are expressed during wine fermentations. We are
currently using a systems biology approach to
establish function for these genes.

enology research | measday lab
S. cerevisiae has evolved to survive constant
fluctuations in its surroundings by rapidly adapting
to meet the challenges of new environments. During
alcoholic fermentation, yeast cells are exposed to a
variety of stresses including high osmolarity, organic
acid stress and ethanol toxicity.
We have also recently established a collaboration with
Dr. Charlie Boone at the University of Toronto to use
a new genomic approach to identify genes that, when
overproduced, confer ethanol resistance to yeast cells.
The ultimate objective of this research is to generate wine
yeast strains that are more resistant to ethanol stress.
Our research combines the genomic technology of lab
yeast with the environmental conditions of wine yeast
to uncover key pathways required for surviving the
stresses imposed by fermentation. Understanding stress
resistance pathways in yeast creates potential to increase
stress resistance in wine yeast, improve industrial
performance and reduce the cost to Canadian wineries of
incomplete (sluggish or stuck) fermentations.
My lab also studies chromosome segregation in
S. cerevisiae using molecular biology, genetic and
genomic tools. Studying chromosome segregation
using yeast as a model system provides important
insights into diseases hallmarked by abnormal
chromosome numbers such as Down’s syndrome
and cancer. Each time a cell grows and divides
its chromosomes must be accurately duplicated
and segregated equally to daughter cells so that
each new cell has the exact same chromosomes
as the mother cell. Duplicated chromosomes are
separated by attaching to microtubules which pull
each chromosome into the daughter cells. We
are interested in understanding how defects in
chromosome-microtubule attachment cause cells to
send a message to stop cell cycle progression until the
attachment defect is repaired.
We are taking a genomics approach to understand the
molecular network of specific fermentation related
stress responses in S. cerevisiae. In collaboration with
Dr. Mike Tyers’ lab (previously at the University of
Toronto, now at the University of Edinburgh), we are
using the yeast deletion set barcode oligonucleotide
method to identify genes that are important for yeast
cell survival during a fermentation.

viticulture research | lund lab
Making the best wines starts with growing the
best grapes. To advance both processes, the WRC
is exploring grapevine biology at the molecular and
biochemical levels.
GrapeGen funding allowed the WRC to initiate research
in 2004 into plant hormone and terpenoid molecular
biology and biochemistry responses to changes in light
exposure to berry clusters in the vineyard.
All viticulturists grapple with the fact that fruit quality
can vary from one season to the next — even in
the same vineyard block — leading to inconsistent
vintages. But what if science can access the plant’s
“black box,” looking at how the vine and berry respond
to changing viticultural practices and environmental
conditions along each season? Growers could then
fine-tune management practices in concert with
changing weather patterns.
WRC scientists are currently building upon these
studies in the Genome BC- and Genome Canadafunded “WineGen” and “Grape and Wine Genomics”
projects to identify and validate molecules that may
be useful in the future to viticulturists as molecular
“biosensors” to assist in vineyard management. This
type of molecular-level monitoring and diagnosis is
made further possible thanks to the recent sequencing
of the grapevine genetic code by European scientists.
Early in the development of WRC’s viticulture
genomics research program, large-scale funding from
the federal government through Genome Canada for
the GrapeGen project played a fundamental role in
the establishment of a new technology platform for
studying grapevine genes, proteins, and compositional
chemistry in British Columbia.
We envision creating tools that viticulturalists could
use to monitor the responses of different grapevine
varieties to environmental changes along each
season. Given such means, Canadian growers could
then increase the net “farm gate” values for their
fruit. As well, Canadian winemakers could produce
higher quality vintages in the styles that the individual
winemakers desire.

Currently, the only molecule-based diagnostic tools
available to viticulturists are used to measure sugar
content and acidity/pH. Some wine making operations
also employ sophisticated gas or liquid chromatography
instruments for quantifying additional chemical compounds
as markers of flavour maturity, such as monoterpenes.
Viticulturists primarily use these tools late in the
season to estimate harvest date. Growers do not yet
have the means, however, to monitor responses to the
interplay of their cultural treatments and changing
weather conditions along the critical “green” and early
ripening stages of berry development. Similarly, there
are few effective devices that can help vineyards check
vegetative stresses from drought or pathogens.
If viticulturists were able to take periodic “snapshots”
using molecular biomarkers for viticulture applications,
they could monitor vine health and assess berry quality
parameters in concert with weather forecasts as the
season advances.
A biomarker can be defined as a molecular factor — a
gene, protein, or chemical compound — that indicates
a physiological or disease state at a distinct time in
a particular tissue or cell type under a defined set of
environmental conditions. In medicine, for example,
biomarkers are used for blood or pregnancy tests.
As “proof-of-concept” for feasibility and efficacy,
the WRC is adapting a portable biomarker detection
tool developed at the University of Washington for
medical applications to survey vines for molecular
indicators of early drought stress prior to visible signs.
In parallel, we are studying organic and synthetic
nitrogen fertilization effects on hormone production,
gene activation, and terpenoid, tannin, and amino
acid composition in berries along multiple seasons for
biomarker discovery.
A portable, hand-held biomarker diagnostic tool could
prove most efficient for on-site vine monitoring in the
vineyard rather than needing to ship samples to an
off-site laboratory. As an immediate goal, the WRC is
looking at developing a biomarker tool that can easily
show when a plant is water stressed, and perhaps
include pathogen detection. Both situations cause high
levels of protein biomarkers from plant or pathogen
and thus are relatively easy to detect. Our longer term
goal is to develop biomarkers indicative of the berries’
ripening state for assessing and forecasting ripeningrelated parameters in the vineyard.
While based in genomics sciences, biomarker
technology does not involve genetic modification
of grapevines and is fully compatible with organic
viticulture practices.

terpene research | bohlmann lab
When sipping on a delicious glass of wine, terpenes
isn’t the first word that comes to mind. Yet, these
hydrocarbons comprise important aroma and flavour
compounds in grapevine berries and wines. Terpenes
are part of a very large group of natural products with
more than 50,000 known compounds.
Dr. Jörg Bohlmann and his team are characterizing
the terpene profiles of grapevines during flowering,
fruit development, and fruit ripening. As well, they are
investigating the genetic underpinnings and molecular
mechanisms that control the chemical complexity
and timing of terpenoid formation in grapevines. In
partnership with an international consortium that
is sequencing and characterizing the grapevine
genome, our team has discovered a large set of genes
responsible for terpene formation in grapevines.
Our research on grapevine terpenes has been
published in prestigious journals such as
Phytochemistry, Science and the Proceedings of the
National Academy of Sciences of the United States
of America.

wine library & vinotheque
Over a period of hundreds of years wineries in
other countries have established which grape
varietals do best in which regions. This has led to
the proclamation of appellation regions in several
countries and only certain varietals are planted
in certain regions. The result has been that wines
produced in these regions enjoy considerable status
and they command high prices.
To establish which grape varietals will do best in
which micro-climatic areas in BC, the Wine Library
was established during 2002. The library can house
approximately 22,000 bottles of wine. The Wine
Library operates under the auspices of a board of
Directors who are knowledgeable about wines.
Wine-aging study
Winemakers nominate young wines produced in B.C. and wineries donate 24 bottles of each wine that have been
selected for study in the WRC. These wines are aged in the Library under temperature and humidity-controlled
conditions. Wines are tasted annually over a period up to 24 years and, based on organoleptic and sophisticated
chemical analysis by Gas Chromatography-Mass Spectrometry (GC/MS) and Liquid Chromatography-Mass
Spectrometery (LC/MS), the WRC will provide feedback to participating wineries to eventually establish a
correlation between viticulture and enology practices in B.C. and the ability of wines to age well.
Support
Donors have kindly donated many bottles of special wines to the WRC. Drs. Bruce Forster and Ritchie Younger
have donated many cases of leading international wines since the opening of the Wine Library. We would like to
thank the following wineries for financial contributions to setup the wine library: Burrowing Owl Estate Winery,
Calona Vineyards, Gray Monk Estate Winery, Mission Hill Family Estate Winery, and Tinhorn Creek Winery.
The following experts have given many valuable hours and serve on our tasting panel: Sid Cross, David Hopgood,
Ian Mottershead, Tom DiBello, James Cluer, Robert Simpson, Bruce Forster, Ritchie Younger, Don Brooks, Sandra
Oldfield, Mark Davidson, Ian Sutherland, John Schreiner and Hennie van Vuuren.
Many prominent scientists, including Nobel Laureates Drs. Sydney Brenner and John Sulston, have visited the
Wine Library. Other honoured guests include Philippe Bascaules, distinguished winemaker from Chateaux
Margaux and Drs. Irving K. Barber and Stewart Blusson, both major donors to UBC.
