Nitrogen in viticulture and winemaking: an exploration from soil 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.

Potassium in viticulture and winemaking: an exploration from soil 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. Potassium is the second most abundant mineral nutrient in plants and has a number of roles. It is associated with the movement of water, nutrients and carbohydrates whilst also helping to regulate stomata and supporting enzyme activation. A deficiency can reduce yields, fruit quality and increase susceptibility to disease. Too much can cause a finished wine to lose acidity. In this article I will explore potassium in viticulture from soil to bottle.

Produttori del Barbaresco: the worlds best wine cooperative?

In 1894, Domizio Cavazza created Barbaresco’s first cooperative, the Cantine Sociali. Cavazza recognised that Nebbiolo from Barbaresco differed from Barolo, and for the first time, acknowledged this on the label. In 1920, fascist rule forced the Cantine Sociali to close, it wasn’t until 1958 that a cooperative reemerged in Barbaresco; the Produttori del Barbaresco. Today, in a good vintage, the Produttori (consisting of 54 growers and 250 acres of vineyards) bottles nine single vineyard wines, a Barbaresco DOCG, and a Langhe Nebbiolo DOC. My appreciation for the Produttori, and Piedmont as a region, came to be in 2015. I received as a gift, a bottle of 2008 Produttori del Barbaresco Pora: the wine was ethereal, seductive and poised. Last year I visited the Produttori and in this article get to grips with what makes this cooperative the best in the world.

Oak in winemaking; dissecting the origin, selection and science of barrels

For over 2000 years oak has been a fundamental component in the production, maturation and transport of wine. First used by merchants as a vessel for transporting finished wine, its capacity to transform the liquid within was arguably a serendipitous byproduct of its initial purely practical use. Decisions associated with the preparation and use of oak in winemaking are arguably some of the most influential in defining style, be that regional, site-specific or that of an individual vigneron. Often under-appreciated, the journey of the oak barrel from forest to cellar reveals an intricate and complex story, one of nature, craft and science.

wine digital revolution

Wine’s digital revolution: adaptation amidst chaos

They say necessity is the mother of invention, or in this case, adaptation. The wine industry has for one reason or another been sluggish in embracing and adopting the digital revolution of the past decade. Whether it be a large multinational or small family-run business, the way in which businesses engage with their captive and potential audience has elsewhere evolved. I don’t want to come across as gloomy, this article is one of optimism and celebration. The now global pandemic has devastated the wine industry, turning many businesses on their heads overnight. However, opposed to accepting defeat, many have shown overwhelming resolve, transforming their strategy almost instantaneously. What has changed and what does wine’s digital revolution mean for the industry going forward?

Vintage by Villa Maria: getting down and dirty with the heroes of harvest

Winemaking is a labour of love. For those on the ground, romantic notions of sniffing barrels and stomping grapes are a stark contrast to their reality. Vintage by Villa Maria is a wine documentary with a difference. The film explores the trials and tribulations of a single harvest from the perspective of Villa Maria’s people. Filmed across 40 days it explores their motivations, passions and the unique challenges they face. In a style attractive to wine lovers and regular folk, Vintage balances new-found admiration with excitement, education and sheer grit.

grape ripeness

Grape ripeness: pursuing the optimum with Ruinart’s Frédéric Panaïotis

Selecting a date upon which to begin harvest is arguably the most pressing, influential and troublesome decision required of any vigneron during the annual growing cycle. There is the romantic notion that growers arrive at this decision as a result of intuitive tasting of selected grapes picked randomly from a particular plot or row. Whilst intuition often proves invaluable, particularly in tough vintages, times are changing and the role of technology in tracking optimum grape ripeness is proving increasingly valuable. In no region are they pursuing optimum ripeness quite as comprehensively than in Champagne. I got to grips with just how this pursuit is evolving with Frédéric Panaïotis, Chef de Cave at Ruinart.

Dr Loosen: exploring Ernie’s refreshing outlook and new ideas

There are few more colourful, vivacious and spirited individuals than Ernst Loosen. Those who have spent any amount of time with him will know well the personality of which I speak. Since the 1980’s he has produced world-class Riesling from the Mosel to Washington State, experimented with Pinot Noir in Oregon and shared his knowledge as far afield as New Zealand. Ernie is an innovator, he pushes boundaries, but most of all he rejects defeatism. Despite a host of existential challenges, with an open mind and curious inquisition Ernst has continued to evolve. I spent an evening exploring this refreshing outlook …

Minerality in wine: exploring the topic from the ground up

As a descriptor, minerality didn’t crop up in the wine industries lexicon until the late 80s. In a recent Decanter article Prof. Alex Maltman recalled writing his first piece on the topic a little over 15 years ago. Maltman posits the term to be of ‘pragmatic usefulness’ despite there being no clear consensus on what it actually means. We wine-lovers are relentless in our indulgent pursuit of translating perception and sensation of wine in to sometimes simplistic terminology. Vast may our parlance be, minerality is arguably amongst the most ubiquitous of its terms. Why is the topic so challenging? Is it helpful? What do we know about it? In this piece I will explore the research and piece together my thoughts.

Burgundy en primeur 2018: thoughts and feelings on the vintage

January has been damp at best. I fear the annual showing of Burgundy en primeur renders any future possibility of a dry month nigh on impossible for me and many alike. This past fortnight the Burgundians, with the help of London’s wine merchants, have offered the wine trade unrivalled access to their 2018 Burgundy vintage offering. In this article I will briefly share my thoughts and feelings on the wines, the vintage and what’s to come for Burgundy.
