Yeast; The Silent Winemaker

Imagine a mid-day snack, some cheeses, marmite on fresh bread toast, maybe a croissant and a glass of wine or cold beer. None would be possible without yeast.

First conclusive results on agrivoltaics in France

Vines thrive under the shade afforded by photovoltaic panels according to preliminary results thrown up by the pilot site in Piolenc, Vaucluse, in the Rhone Valley. Out of 1,000 m2 of vines planted to Grenache noir, 600 m2 were covered with solar panels developed by Sun'Agri.

‘Tressage’: an alternative to hedging vines, that claims to have some benefits

‘Tressage’: an alternative to hedging vines, that claims to have some benefits

In viticulture, a widely practiced form of leaf removal is hedging of the canopies, taking off the developing shoots at the top, as well as any extra growth sticking out into the row. The goal here is twofold: to tidy up the vineyard by removing unwanted growth, and also to slow down the vegetative phase of growth and get the vine to focus on fruit ripening.

Brettanomyces spp. control: a research-winery crosstalk.

Brettanomyces spp. control: a research-winery crosstalk.

The Brettanomyces spp. contamination during winemaking and its persistence in the cellar have a detrimental effect on the high-quality wines and produce economic losses worldwide. The Brettanomyces spp. wine spoilage is largely due to the volatile phenols (VPs) production with a depreciation of the wine bottles.

Nitrogen in viticulture and winemaking: an exploration from vine to bottle

Nitrogen in viticulture and winemaking: an exploration from vine to bottle

Besides that which is essential for photosynthesis, namely carbon dioxide, water, and sunlight, grapevines also require a range of nutrients in order to grow, survive and prosper. These nutrients are split into two groups depending on scale of requirement, macro and micronutrient, the former being those required in larger amounts. Nitrogen is the most abundant soil‐derived macronutrient in the grapevine. It plays a major role in all processes and a significant amount of nitrogen is essential for normal vine growth. In viticulture a nitrogen deficiency may affect key metabolic functions and retard shoot development and bunch formation. In winemaking a shortage of yeast assimilable nitrogen can result in problematic fermentations. In this article I will explore nitrogen in viticulture from soil to bottle.
