Grape pomaces are increasingly being used as starting material in the industrial production of plant food supplements (PFS), food coloring and tartrates but they are at risk of ochratoxin A (OTA) contamination, a mycotoxin with nephrotoxic and carcinogenic effects. We analysed 24 commercial PFS and 13 food coloring samples derived from Vitis vinifera, mainly pomaces, using a HPLC-FLD method for OTA determination. OTA was found in 75% of PFS samples and 69% of food coloring samples at levels of
Since the early 2000s, the amount of land planted in wine grapes throughout New Zealand has increased by a whopping 100 per cent. In the last 12 years, according to Statistics New Zealand, between the years 2002 and 2014, the area of land planted in grapes has leapt from 17,300 hectares to 34,130 hectares.

Bulgarian wine exports to Russia have marked a considerable decrease. In the words of Krasimir Koev, head of Bulgaria’s Execute Agency on Vine and Wine (EAVW), the main reasons are the tragic events in Ukraine as well as the devaluation of the Russian ruble, as reported by the Argumenti Nedeli daily. Koev noted that up until 2014, half of the Bulgarian wine production was exported to the Russian market. In his words, the number of orders truly reached ”cosmic dimensions”.

Grape extracts can be added to milk to produce cheese with a high concentration of polyphenols. Four commercial extracts from whole grape, grape seed, and grape skin (2 extracts) were characterized and added to milk at concentrations of 0, 0.1, 0.2, and 0.3% (wt/vol). The effect of grape extracts on the kinetics of milk clotting, milk gel texture, and syneresis were determined, and model cheeses were produced. Whole grape and grape seed extracts contained a similar concentration of polyphenolic compounds and about twice the amount found in grape skin extracts.

Oak barrels have long been the preferred method for oak maturation of wine, but barrels contribute significantly to production costs, so alternate oak maturation regimens have been introduced, particularly for wines at lower price points. To date, few studies have investigated consumers’ acceptance of wines made using non-traditional oak treatments. In this study, two Cabernet Sauvignon wines were aged using traditional (i.e., barrel) and/or alternative (i.e., stainless steel or plastic tanks and vats, with oak wood added) maturation regimens. Chemical and sensory analyses were subsequently performed to determine the influence

Nearly 20 million tons of winery by-products, with many biological activities, are discarded each year in the world. The extraction of bioactive compounds from Chenin Blanc, Petit Verdot, and Syrah grape by-products, produced in the semi-arid region in Brazil, was optimized by a Central Composite Rotatable Design. The phenolic compounds profile, antioxidant capacity against synthetic free radicals (DPPH and ABTS), reactive oxygen species (ROS; peroxyl radical, superoxide radical, hypochlorous acid), cytotoxicity assay (MTT) and quantification of TNF-α production in RAW 264.7 cells were conducted.

Marketers need to take on new consumer trends and adapt to a changing market, according to a new Wine Intelligence study released today.

Although the mass market appears to be shifting towards globalisation, Halstead says individuals are seeing the value in local products.
