Alvi’s Drift is situated on the shores of the Breede River near Worcester and the colourful name is derived from the nearby low water bridge, which gives secure access over the river. The farm was established in 1928 and the first owner, Albertus Viljoen van der...
Although wine barrels were traditionally made from different types of wood, oak wood was associated with it in the course of time. If the mystic of France is added to it the romantics of barrels was kick-started. Are the French oak forests however sustainable to meet...
Aim of the study The study investigated the preferences and order of uptake of nitrogen sources for various commercially available non-Saccharomyces yeasts. The influence on growth and fermentation kinetics, as well as aroma formation, was also investigated. The study...
Current and previous names Schizosaccharomyces pombe has previously been designated several species names based on classical yeast taxonomy methods; amongst its synonyms are S. vordermani, S. mellacei, S. fermosensis, S. santawensis, S. pinan, S. taito, S....
This study aimed to investigate flavan-3-ol and anthocyanin evolution and composition under altered microclimatic conditions in Cabernet Sauvignon grown in the Stellenbosch Wine of Origin District. Introduction Flavonols are colourless compounds which are...
Bentonite is most probably one of the additives used most generally during winemaking. It can be used together with other fining agents for the clarification of juice or wine, but is mainly used for the protein stabilisation of white wine. Its use has however certain...
Powdery mildews have been around for millions of years. As time progressed, they evolved and are acutely able to sense and utilise light to develop optimally. Knowing this, scientists can cleverly use their superpowers against them. Is this completely new...
This study aimed to investigate flavan-3-ol composition under altered microclimatic conditions in Cabernet Sauvignon grown in the Stellenbosch Wine of Origin District. Introduction Proanthocyanidins or condensed tannins are mostly situated in the solid parts of...
M. pulcherrima is least influenced by must nitrogen composition compared to S. cerevisiae and other non-Saccharomyces yeasts frequently encountered in wine fermentation. Current and previous names Metschnikowia pulcherrima has previously been designated under...
Lutzville, which is situated close to the Olifants River, was previously known as Vleermuijsklip after a rock formation outside the village. The rock formation is a national monument and one can clearly see the marks left by elephants long ago as they scoured against...
The aim of this study was to determine the occurrence of Eutypa-like species associated with dieback and canker-affected grapevines and to determine their status as grapevine pathogens. Introduction The trunk disease complex which comprises of grapevine canker...
This study aimed to investigate flavan-3-ol biosynthesis under altered microclimatic conditions in Cabernet Sauvignon grown in the Stellenbosch Wine of Origin District. This was part of a larger study in which flavonoid evolution and composition by manipulating the...
The final part of the series deals with the transition of fundamental research into the domain of the decision maker, through web applications to aid long and short term decision making in the context of climate change. Highlights from previous papers in the...
It is all about the (wine) matrix. The work presented in this article forms part of a series of experiments on the interaction between thiols and red wine matrices as described in Part 1. Background The key word for this latest aspect of thiols in red wine...
Torulaspora delbrueckii is generally regarded as a low producer of aroma compounds, in particular higher alcohols and esters, however, this is strain dependent. Current and previous names Torulaspora delbrueckii has had many synonyms, amongst them Saccharomyces...
Brett has become a fashion word in the wine industry. Although it causes typical off-flavours, other wine faults that are not caused by it are also sometimes attributed to it. It applies especially when some wine writers are looking for descriptive terms to evaluate a...
Who did what? Australian researchers found that acrylic-acid-based plasma polymer coated magnetic nanoparticles can effectively protein stabilise white wines. Why was this investigated? Currently mostly white wines are treated with bentonite before bottling....
Yeast strains vary significantly in their ability to produce varietal thiols. Introduction The varietal thiols, mainly 3-mercaptohexan-1-ol (3MH), 3-mercaptohexyl acetate (3MHA) and 4-mercapto-4-methyl-pentan-2-one (4MMP) are the three major varietal thiols...
