Buy Unripe Grapes
Among the viticultural techniques developed to obtain wine with reduced alcohol content, the use of unripe grapes with low sugar and high malic acid concentration, harvested at cluster thinning, was recently explored. So far, no studies have evaluated the fermentation performances of Saccharomyces in unripe grape musts, in terms of fermentation ability and reducing malic acid contents, to improve the quality of this low-alcohol beverage. In this work, we evaluated 24 S. cerevisiae strains isolated from Italian and Croatian vineyards with different fermentation aptitudes. Moreover, four S. paradoxus were considered, as previous works demonstrated that strains belonging to this species were able to degrade high malic acid amounts in standard musts. The industrial strain S. cerevisiae 71B was added as reference. Sugar and malic acid contents were modified in synthetic musts in order to understand the effect of their concentrations on alcoholic fermentation and malic acid degradation. S. cerevisiae fermentation performances improved when glucose concentration decreased and malic acid level increased. The conditions that simulate unripe grape must, i.e. low glucose and high malic acid content were found to enhance S. cerevisiae ability to degrade malic acid. On the contrary, S. paradoxus strains were able to degrade high amounts of malic acid only in conditions that resemble ripe grape must, i.e. high glucose and low malic acid concentration. In fermentation trials when low glucose concentrations were used, at high malic acid levels S. cerevisiae strains produced higher glycerol than at low malic acid condition. Malic acid degradation ability, tested on the best performing S. cerevisiae strains, was enhanced in fermentation trials when unripe grape must was used.

Raised virtually in the shadow of Chateau Routas, Philippe Saraciva has Varois dirt under his nails. He discovered his life's work early on, learning from his grandfather how to taste grapes for ripeness and prune the vines in wintertime. He joined Chateau Routas fresh out of school. "Professionally, I grew up here," he reflected.
Philippe sees his challenge as producing the best possible grapes for winemaker Jean Louis. With over sixteen years of experience working together, the two have a near-telepathic rapport, timing the harvest for optimum acidity and complexity of flavor and adopting the time honored method of hand picking for all their grapes.
Chateau Routas abounds in the agricultural diversity that is key to vine health. The estate's 260 hectares encompass wheat fields and olive trees, and black truffles stud the earth. Red poppies give way to brilliant yellow sunflowers, and in the fall, the surrounding forests yield abundant mushrooms-cepes (porcini), fragile girolles, and morels. Helpful insects play their part in keeping the vines disease-free. The terrain is punctuated by a stunning geological anomaly, the 885-deep Infernet Hole (Devil's Hole), a canyon thought to have been created by a meteor collision. The hole is a favorite refuge of the local wild boars, which are unfortunately a little too fond of the Chateau Routas grapes!
As in all the best properties, the Chateau Routas soil varies dramatically, resulting in small vineyards that are often unusually shaped. Some plots are red as crushed brick, while others are of crumbly grey limestone mixed with bright red stones that bleach in the hot summer sun. At 1,300 feet above sea level, the elevation is among the appellation's highest, providing cool nights that slow the ripening of the grapes, contributing complexity and dictating harvests that are up to a month later than those below.
Originating from the Near East, the grape varieties that have been brought together in Ampeleia are often found in Mediterranean farmlands and contribute to assert their varied identity, rich in subtleties. In past times, vineyards were not planted with just one grape variety but many types of grapes were present and they were all harvested at the same time.
In 2001 we began building the cellar, designed in close relation to the vineyard according to two main criteria. The first was that every production stage, from the arrival of the grapes to the descent of the wine into the ageing cellar, would take place by gravity, avoiding the brusque use of pumps. The second, fundamental criterion was that the winemaking cellar and the ageing cellar would be organised in such a way as to allow the separate vinification and maturation of each batch of every variety, as though each were a creature in its own right. Thanks to this, when it is time to blend the wines, we have an extraordinary range of possibilities on which to base our choices. This is why, more than an estate of 28 hectares, we like to describe it as an estate that is 28 times one hectare.
Since 2007, we have left the grapes to ferment spontaneously, thanks to the autochthonous yeasts present on the berries and in the air. This is also the reason why the building, designed by the architect Sergio Bracco, is surrounded by the vegetation terraces that merge it with the neighbouring environment.
The grapes are hand-picked and the grapes are transported by crates. In the winery, the vats are made by gravity in tanks made of raw cement. Reassembly and racking Logo-ab When juices and wines ask for it. Sulfur is there only if it is necessary ... Tasting, omnipresent during vinification and raising, leads the decisions.
Domaine des Diables belongs to the children of the Fabre family who harvested their first grapes from the estate in 2007. The soils of the Domaine des Diables offer a perfectly balanced texture comprised of clay, silt and sand, which is ideal for producing full-flavoured and highly aromatic rosé wines. A significant proportion of gravel and stones can be observed in the soil's composition. Driven by the ambition of surpassing their parents, all of the wines produced by the Fabre children at the Domaine des Diables have been classed top in their category at the various wine competitions and by wine guides. All of this hard work proved particularly worthwhile from 2011 , the Domaine des Diables was awarded the Prix d'Excellence at the Concours Général Agricole de Paris in acknowledgement of the consistent quality of winemaking at the estate since its creation. Thanks to its rosé wines, the Domaine des Diables, has fifth been awarded the Prix d'Excellence at the Concours Général Agricole by the a representative of the French Minister of Agriculture, Bruno Lemaire. Domaine des Diables is the only Provençal estate, among hundreds of candidates, to have received an award in 2011, 2012, 2013, 2014,2015, and for the fifth year running at that. This Prix d'Excellence rewards the consistent quality of the estate's wines while certifying, in particular, the use of good winemaking practice as well as quality of flavour in the wines.
Throughout the vines' entire growing cycle, the soil is regularly hoed to eliminate weeds and limit the effects of drought. The fertilizers they use come from the vine: after fermentation, the grape stalks and grapes are distilled and then returned to the soil. The vine shoots are also ground down to ensure that the soil retains a certain level of stable organic matter. Each year, in autumn, they allow a shepherd to bring his herd of sheep to pasture in the vineyard, as was commonly the practice in days gone by.
Adrien works with respect for the environment using organic techniques tending towards Biodynamic, that he adapts to each parcels depending on the treatment needed to obtain the healthiest vines and grapes. Atop of not using any herbicides or inorganic fertilizers, working and plowing the ground are done with small tools to avoid tamping the soil and in the same time allow the upper ground layers and roots to breath. Everything is done mainly by hand and using a tractor will be too dangerous anyway due to the steepness of the slope in certain parcels.
Aggressive pruning is carried out multiples times throughout the year to help keep yields low and ensure that only the finest fruit remains on the vine. The grapes are mechanically harvested at their peak between mid September and early October, depending on the vineyard, allowing them to work quickly and capture the fruit at its peak.
State-of-the-art machinery is utilized throughout the winemaking process, but tradition is not forgotten. Upon reception at the winery, the grapes are gently pressed using a pneumatic press. The free-run juice is transferred to stainless steel tanks by use of gravity to undergo fermentation using only ambient and natural yeasts from the vineyard. The white wines are briefly aged on fine lees to add complexity, while the reds spend a fair amount of time in French oak barrels. In keeping with tradition, all work done in the cellar is based on the lunar calendar.
Once in the winery the grapes are vinified separately and according to their variety and the terroir from which they came. Cruzille, for instance, is identified for its very mineral-driven wines and their ageing potential.
Domaine Duseigneur Joanna is made from 100% old vine Grenache. The grapes are selected from specific parcels of very old vines. Some of the vines used for this cuvee planted in the Colombis lieu dit are over 130 years of age! The wine is aged for 18 months in demi-muids. The production is less than 175 cases per vintage.
We clean them off, excited to eat them, and then boom, we are stopped right in our tracks, with the disappointment of having just tasted a sour grape. You hope it's only a fluke, only to realize that after several test subjects fail, that you are now an owner of a bag of sour grapes.
How could this happen? The sign at the store promised that these grapes were sweet - how could a grocery store sign let me down. Be assured that your disappointment did not begin in the grocery store, but out in the field - where profit often trumps flavor and sweetness.
There are several factors that play into why grocery store grapes are so inconstient - sometimes sweet, sometimes sour, sometimes flavorful, often times not. Grapes are picked when they appear ready, even if they haven't reached their peak levels of sugar and flavor. They quicker they are picked, the quicker money can be made. If the sign and appearance of the grape is there, then it's removed from the vine. Often growers remove all the grapes at once. Problem is that not all bunches are ready at the same time. It takes a skilled picker to determine which grapes are perfect, and which need more time. That requires more money on the part of the grower to pack more skilled workers and to spend time go back over the same vines. It's cheaper to pay someone to pick them all and move on. 041b061a72
