At this time of year the larvae commence their nightly ascents in search of juicy young buds. They seem to selectively shear away the woolen jacket in order to reach the green goodness below. In doing so, they have robbed me of a summer cane which will potentially carry three bunches of riesling berries. On a good night, they will make their way along a whole cane, stripping every bud they come across. Spur-Pruning minimises the damage.
Grapevines have flowers? This phenological event goes unnoticed to an untrained eye. Flowering however plays a massive role for the viticulturist. The potential yield is strongly influenced within this 1-3 week period. The rather unspectacular flowers have petals (known as “caps”) which are fused around the reproductive organs (stamen, stigma and ovary). Below are some images from our vineyard this week.
Pre-Flowering: Below, most caps have fallen however two can still be seen on the lefthand side of this future Riesling bunch. Notice the sticky Stigmas surrounded by the Stamen (made up of the pollen-carrying anthers supported by the white filaments). Once the stigmatic surface has been pollinated, the pollen grain germinates, sending a 2mm tube down to the Ovary which leads to fertilization and fruit set.
At this point the grape grower receives the first indication of potential yield. The tiny berries have arrived and the vine begins to focus on the growth of these baby bunches.
At the Mosel we have many small parcels of fruit (many small vineyard blocks). The advantages of having varying vineyard sites at the Mosel are differing altitudes, orientations, soil structures, vine ages and rootstocks. This leads to lots of interesting ingredients when making a wine….a touch of primary fruit from there, some lively acidity from up there and some palate weight from over there.
That is how we make our new Riesling range – NECTO (in Latin – to connect/bind).
NECTO is produced in three styles to show off the diversity of riesling from the Mosel:
Growing exciting riesling wines at the Mosel in Germany allows incredible creativity, in both the vineyard and cellar. Creativity in winegrowing requires direction and clarity in order to achieve the best results in the glass. Making riesling at the Mosel is all about style. Each mesoclimate (individual vineyard sites or areas within vineyards) has a set of characteristics which we aim to preserve by caring for the microclimates (around the vines themselves) within. You can choose to blend these mesoclimates based on their attributes (i.e. the higher site has a tighter structure in comparison to the site closer to the Mosel which displays a riper composition) or bottle single-vineyard wines. Blending these different attributes can create a unique outcome in the form of a riesling which defines the winemakers philosophy. To suffocate this creativity with a rulebook is a crime. A crime we unfortunately endure on an annual basis.
At the Mosel you can work endless hours in the vineyard, fine tuning the microclimates to grow the grapes needed for a particular style of riesling. The grapes are harvested and pressed to juice so the fermentation process can begin. The ferment is tasted daily to track flavour development and the intricate balance between sugar and acidity. You enter the cellar one day and taste the ferment – the very style you spent a year planning has been achieved. You analyse the residual sugar and get a result of 12g/L. At this point your creativity comes to a screaming halt as the maximum level of residual sugar for a dry riesling at the Mosel is 9g/L. In order to write dry (trocken) on your label you have to adhere to this restriction. Your customers want to know if the wine is dry, medium-dry or sweet and you want to give them the most harmonious result from that vintage whilst disclosing the wines’ taste profile which is well-suited to certain foods and occasions. What do you do? You post your dilemma on a blog 😉
“Slate soil Riesling with 15 grams of residual sugar can taste perfectly dry.” Echensperger, Romana. “The Diversity of German Riesling.” TONG 21 March. 2011: 3-16. Print.
But don’t worry, in 2000 the authorities added two new categories to give the producers some breathing room, “Classic” and “Selection.” Just what the winemakers needed – a need to further educate their already bewildered customers. And don’t think the fun stops with residual sugar. We could write a book on the lack of continuity in the so called, ‘Qualitätsstufen.’ The Germans have created a logistical nightmare for anyone trying to market a Mosel riesling. It is astonishing to think that a system introduced to provide direction and clarity can produce such a grey zone for the people who really count – the consumer. As climates change and styles of riesling evolve, winemakers at the Mosel will adapt and redesign their approach to producing riesling. Unfortunately the current framework in which they are forced to create their wines, is dictating the final outcome in your glass. The 3 grams of sugar could be the difference between a good wine and a great wine.
Solution: Transparency! Write the exact residual sugar level on the label. It would be a lot easier to explain that anything between 10 and 12 grams tastes ‘more or less’ dry, 12-25 medium dry and anything over will be relatively sweet. This pared with the second tool (which the riesling fans already use) % alcohol will probably solve a few problems. In any case the Mosel producers will be growing their best (most harmonious) wines.
Perhaps a scale – like the one used by Domaine Zind-Humbrecht:
Indice 1: analytically dry or tasting dry.
Indice 2: not analytically dry, but the sweetness is not apparent on the palate
Indice 3: a semi-sweet wine
Indice 4: a sweet wine;
Indice 5: high sweetness,
Ah, ventilation! So, I’m off to design our new labels and don’t be surprised to not find the words Trocken, Halbtrocken, Feinherb, Lieblich or Süss on there. Wine quality won’t be jeopardized by a term. Hauptsache: the wine is the best it can be!
The Hobbit Project is alive! If you had ever dreamed of making your own wine or you’d like to become part of a global team of winemakers – here is the chance. The Hobbit Project is a great way to expose yourself to winemaking whilst becoming part of the a very unique culture found only at the Mosel Valley in Germany. Click the link above to join our clan…..
The word on the grapevine is that Crushpad will be announcing a project at the Mosel Valley in the coming weeks for the 2011 vintage. So, all you riesling fans (and anyone interested in a unique cultural experience from the comfort of your own living room) get on over to the Crushpad website to see how you become the winemaker. More detailed information regarding the Mosel Valley coming soon….
This two year old vine (one year old cane which will become the trunk) has started to lose it’s soft baby skin and replace it with some sun-exposed leather…..sound familiar? Hey, put some cream on, you’re getting burnt……just lignifying baby.
You may have heard the word ‘rootstock’ being thrown around during discussions about grape varieties and vineyards. In viticulture, a rootstock is the type of vine selected to be the root system (i.e. 5c) for the fruiting variety (i.e. riesling). The fruiting variety is usually a european wine-producing Vinifera vine and the rootstock is normally American in origin. The American rootstocks are used to overcome soil diseases, pests and other soil conditions. The images above display the differences between the rootstock (5c) and the grape variety (riesling). The image on the right displays the graft and a cane growing from either side of the graft. The leaf anatomy is also obviously different between the two – the riesling is the lower of the two leaves.
