Yeast nutrition

For a disturbance-free fermentation, a good nutrient supply of the yeasts is required. Only under optimized conditions, the yeast is able to convert the sugar entirely to alcohol and form the desired fermentation aromas at the same time. A lot of wines, or even most of the wines, are not sufficiently provided with nutrients. Rot further reduces the natural nutrient reservoir. As a rule, it therefore makes sense to add a combination product for optimal yeast nutrition to the grape must, thus preventing a lack of nutrients and assuring a safe fermentation process by this measure.

Yeasts / Fermentation /

Alcoholic fermentation is simply the basis of winemaking. And as a matter of course, dry selected yeasts are applied for a quick fermentation onset, for a securely completed final fermentation and to produce wines with clean aromas. By special yeast selections, the varietal character and different aroma profiles of the wine can be very well promoted. In addition, specially selected red wine yeasts support colour stabilisation.

Malo-lactic fermentation

White wines with pronounced acidity are less and less expected by consumers. The trend goes towards very well structured, well balanced, acid-reduced modern white wines which meanwhile can be produced in an excellent way by using selected lactic acid bacteria. Malo-lactic fermentation is particularly suited for the grape varieties Pinot blanc and Chardonnay. But also for Riesling a treatment with starter cultures to reduce acidity could have a positive effect. In red wine-making malo-lactic fermentation simply is a must. Lactic acid bacteria form various by-products when converting malic acid to lactic acid which provide the red wine with a pleasant velvety softness, enhanced structure and desired, targeted aroma profile. The resulting wines are characteristic, sensory evaluation is brilliant.

Special sedimentation materials

Beside the conventional clarifying agents, different sprecial products are in use which due to their composition and processing, are particularly adjusted to certain application cases in wine, e.g. high pH-values, low temperatures, wines problematic to filtrate, well-balanced red wine technology or tannin harmonisation at the same time. By the application of these products, further quality increases can be realized.

Oak chips

The positive effect of oak wood on wine quality is uncontested. There is a great difference between wines stored in wooden barrels and wines stored in tanks. When applying oak chips similar effects can be achieved. The use of oak chips accelerates maturation and dependent on the choice of the respective oak chips, the wine aroma varies and can be directed towards a certain desired aroma profile. Another important factor in favour of the use of oak chips, is the saving and sustainable conservation of the slowly growing raw material oak wood, since the required wood quantity is considerably smaller compared with the quantity needed to make barrique barrels. On red wines, oak chips have an additional and important colour stabilizing effect, due to increased polymerisation. In the EU, oak chips are not permitted at present, but in an advanced stage of approval.

Other clarificaion products, stabilization

The Wine law allow to use many winetreatment products. The sensory of the wines in differnet vintages, by different wines can be affected by the acidification. A wine with microbiological disorders cannot be sold. Besides cellar hygiene, sufficient sulphuring and permanent SO2-control are the decisive factors to assure that bottled wines are not microbially infested. Vitamin C and sorbic acid have a supporting effect.

Diatomaceous earth, perlite, filtration additives

The filter aids kieselguhr and perlite facilitate or even only make filtration possible. Filtration effect and filtration performance can be increased by cellulose fibrils. Long-fiber cellulose allows a processing of deposits from must racking and deacidification without special devices and equipment.

FILTROX filter sheets

FIBRAFIX depth filter sheets represent an approved and established filtration technology for solid liquid separation. The three dimensional medium assures superior retention capacity for solid particles at a high flow rate. The pore sizes can be fine enough to retain bacteria and thus produce a sterile liquid. The dirt holding capacity of a FibraFix depth filter sheet can be up to 4 kg per m². In the filtration process, solid particles are slowed down and eventually retained by the tortuous path inside the filter sheet and by electrokinetical interactions. Through this unique mechanism, a high capacity (long lifetime of filter until plugging) can be achieved.


CARLSON filter sheets

Since 1988 Carlson Filtration has been part of the Swiss based Group FILTROX AG. Through out its lifetime the company has developed a strong position in the market place for depth filtration media, modules and supporting equipment. Its products are used in multiple industries, including spirits, wine, brewing, fruit juices and other food related applications. Carlson Filtration develops, manufactures, markets and distributes a broad range of products to suit all applications. From the Barnoldswick factory the company distributes products through the UK and to over 130 countries worldwide.


Filter cartridges

Filter cartridges are used for the clear filtration of liquids with low solids content up to a maximum of 0.1 percent by weight. Possible applications for filter cartridges range from particle separation through depth filter cartridges (BECO PROTECT) to sterile filtration and separation of micro-organisms via membrane filter cartridges (BECO Membrane). With separation limits between 100 µm and 0.2 µm, the BECO cartridge range covers a very broad spectrum of liquid filtration applications. Moreover, a variety of filter media and types are available. In addition to different filter lengths between 10" (25 cm) and 40" (100 cm), a variety of adapter types are available.


NOMACORC synthetic closures

Patented co-extrusion manufacturing process creates engineered closures with a foamed core and an outer skin. These two elements work hand in hand to create predictable and consistent preservation results. The core is breathable and allows optimum oxygen transfer rates through the closure, while the outer skin provides a precise and consistent seal. In addition to its function, the skin has the appearance of natural cork and preserves the traditional ceremony of opening a bottle of wine, making Nomacorc appropriate for any and all occasions. BEFORE BOTTLING PLEASE READ THE BOTTLING GUIDE AND ASK FOR SAMPLES! Specific printing is also available, please ask for information!

Laboratory products

For the correct and professional winetreatment it is necessary to know the analitycal parameter of the wines. The knowledge of the analitycal parameter help us to make the sufficent sulfuring or monitoring the malo-lactic fermentation. For the stabilization of the wines is it necessary to now how high is the bentonit demand, for this reason we can use the Bentotest.


Wigol cleaning products

The bottom line of making good and fine wine is to keep clean the cellars. More than 55 years ago the company WIGOL W. Stache GmbH had been founded at Worms on the Rhine. We produce cleaning and disinfecting agents for the beverage, food, pharmaceutical and cosmetics industry as well as degreasing concentrates and anti-corrosion agents for the surface technology.


Products for breweries

Smell, taste, clarity, foam, and colour are the criteria by which the consumer judges a beer. The increase in global beer production and in customer demands require safe quality parameters for at least one year.

Pronektar’s oak products for wine-making are made from strictly selected oak timber, and offer a wide range of technical and economic solutions adapted to what winemakers are seeking for their wines.


Filtrox

FILTROX GROUP is focused in a niche in the global filtration market. Depth filtration of valuable liquids by means of depth filter systems is our world. In our specialized field, we are proud to be the leading company worldwide. FILTROX is focused in depth filtration, that means on the removal of solid particles in the size of 0.1 to 10 microns, generally referred to as microfiltration. Typical microparticles are bacteria, yeast cells, cell fragments, or proteins. These particles are not visible for the human eye, but they make the liquid turbid so that one cannot see through. Through microfiltration, the liquid becomes clear.
