In warm irrigated regions of Australia (such as Sunraysia), pH of grape juice often tends to be high (e.g. > 3.8). A high juice pH is undesirable for the production of quality wines as it results in wines of low quality for example, reduced colour stability and poor taste. Such a high juice pH is typically associated with a high concentration of K in the juice, depending on  the scion, rootstock and location. Potassium is an essential nutrient and plant genotypes, including grapevines, differ… 
Fertilization of temperate fruit trees, such as grapevine (Vitis spp.), apple (Malus domestica), and pear (Pyrus communis) is an important tool to achive maximum yield and fruit quality. Fertilizers
Regulation of fruit and wine quality parameters of 'Cabernet Sauvignon' grapevines (Vitis vinifera L.) by rootstocks in semiarid regions of India
Area under wine grape cultivation is increasing in semiarid tropical regions of India. There is lack of information on role of rootstocks influencing must composition and thereby wine quality under
Grape (Vitis vinifera L.) production and soil potassium forms in vineyard subjected to potassium fertilization
Abstract Potassium fertilization can change K forms available in the soil, as well as influence plant absorption of it and yield but, mainly, it can affect grape composition. The aim of the current
Tuning Potassium Fertilization to Improve pH and Acidity in Glera Grapevine (Vitis vinifera L.) under a Warming Climate
Potassium concentration in grape berries can affect acidity and pH in must and wines. Under the current warming scenario, where preserving equilibrated value for these grape parameters is
Using rootstocks to lower berry potassium concentrations in 'Cabernet Sauvignon' grapevines
Potassium is the most abundant cation in grape berries. It has important roles in grapevine physiology and winemaking. This study investigates the feasibility of using rootstocks to lower berry
Yield and grape must composition in ‘Cabernet Sauvignon’ grape vine subjected to potassium fertilization in high altitude soil
Potassium applications in the soil did not affect yield, but K concentration increase in the leaves led to increased TSS and pH values in grape must, as well as to TA and tartaric acid decrease, a factor that can impair the quality of wine.
Grape yield, and must compounds of 'Cabernet Sauvignon' grapevine in sandy soil with potassium contents increasing
Content of exchangeable potassium (K) in t soil may influence on its content in grapevines leaves, grape yield, as well as, in must composition. The study aimed to assess the interference of
Rootstock and harvest season affect the chemical composition and sensory analysis of grapes and wines of the Alicante Bouschet (Vitis vinifera L.) grown in a tropical semi-arid climate in Brazil
There is a rootstock effect and a harvest season effect for several parameters on grape composition, as well as on the resulting wines, and an influence of rootstock and harvest season (semester/climate) on grape and wine composition is demonstrated.
Potassium in viticulture and enology
Potassium (K+) is of interest to Virginia vintners, as many of the soils upon which vineyards have been planted have high exchangeable K+ levels and while excessive K+ does not cause “toxicity”, high


A review of potassium nutrition in grapevines with special emphasis on berry accumulation
Potassium (K) is essential for vine growth and yield. Grape berries are a strong sink for K, particularly during ripening. Excess K levels in grape berries may have a negative impact on wine quality,
Accumulation of potassium in grapevine rootstocks (Vitis) as affected by dry matter partitioning, root traits and transpiration
The results show genetic differences between grapevine rootstocks in K uptake and transport, and highlight the importance of growth, dry matter partitioning, root traits and root pressure, and the lack of significance of transpiration, in the accumulation of K.
Uptake and distribution of potassium by grapevine rootstocks and its implication for grape juice pH of scion varieties
Differences in petiole K+ concentration of ungrafted grapevine rootstocks grown under field conditions at Merbein, Victoria were compared with the rootstock effects on grape juice pH of the scion varieties Chardonnay and Ruby Cabernet to demonstrate that differences between rootstocks in the extent of K+ accumulation in the shoot are a major determinant of the rootstocks effects on Grape juice pH.
Effects of High Rates of Potassium Fertilization on Raw Product Quality and Changes in pH and Acidity during Storage of Concord Grape Juice
Excessive levels of potassium (K) fertilizer (225 to 900 kg/ha) were applied to Concord grapevines for five years in a vineyard with adequate initial levels of petiole K. Petiole K increased from
Effect of potassium, magnesium and nitrogen supply on grape juice composition of Riesling, Chardonnay and Cabernet Sauvignon vines
Most treatment effects on grape juice composition were quite small, but nevertheless significant, indicating that particular fertiliser applications could be used as a management tool for the production of quality winegrapes.
Accumulation of potassium in grapevine rootstocks ( Vitis ) grafted to ‘Shiraz’ as affected by growth, root-traits and transpiration
The positive impact of root based factors, specifically root traits and root pressure than other (e.g. shoot/roots dry weight, transpiration) in the accumulation of K in ‘Shiraz’ grapevines when assessed as grafted vines on a range of rootstocks is highlighted.
Effects of the rootstock Ramsey (Vitis champini) on ion and organic acid composition of grapes and wine, and on wine spectral characteristics
The influence of Ramsey, used as rootstock of the scion cvs Muscat Gordo Blanco (syn. Muscat of Alexandria), Shiraz (syn. Syrah), Riesling, Cabernet Sauvignon and Chardonnay, on the characteristics
Effect of Salinity and Rootstock on Concentration of Potassium, Calcium, Magnesium, Phosphorus, and Nitrate–Nitrogen in Thompson Seedless Grapevine
Abstract The effect of salinity on potassium (K), calcium (Ca), magnesium (Mg), phosphorus (P), and nitrate–nitrogen (NO3–N) concentration and partitioning was studied in a hydroponic culture of
Potassium nutrition of Cabernet Sauvignon grapevines (Vitis vinifera L.) as affected by shoot trimming
If shoot trimming is not followed by an adequate regrowth of secondary shoots an excessive depletion of potassium from the retained old basal leaves occurs during fruit maturity and increases the risk of leaf K deficiency, particularly in the K0 treatment.
Comparison of the effects of rootstock on crop, juice and wine composition in a replanted nematode-infested Barossa Valley vineyard
Shiraz grapevine scions grafted to Ramsey, Dog Ridge, Harmony, Schwarzmann and 1613 rootstocks outyielded Shiraz on their own roots in a replanted, nematode-infested vineyard in the Barossa Valley.
