Freeze concentration of wine
The advantages of freeze concentration can especially be applied for various alcoholic products such as wine. (Download our brochure)
Why using freeze concentration.
Freeze concentration is easily applied for various water containing high quality food products including e.g. orange, grapefruit, berry fruits and many other fruit varieties as well as alcohol containing product.. No other technology can provide as high quality concentrate as efficiently as freeze concentration. Selective water removal at freezing temperatures ensures total retention of all of the original flavor and aromas. The reconstituted products are comparable to fresh. The reconstituted product competes with product “not from concentrate”. It has the same quality characteristics while the price can be lower.
The water removed from the product is testimony to the quality of the concentrate.
It is therefore that freeze concentration is a feasible concentration technology to obtain concentrates with “natural” characteristics in taste, flavor and appearance

Applications of freeze concentration for wine
The wine is being concentrated at freezing point temperature while no alcohol losses occur with the separated water. Reconstituted wine is comparable with the original wine.
The volume of standard wine can be reduced to half of its original volume without abusing the specific and natural characteristics of the wine.
Reasons for concentrating wine:
- Reduction of storage cost
- Increased storage capacity
- Higher product stability
- Lower distribution cost
- Lower packaging cost
- Longer shelf life
- Use of wine based alcohol concentrates
- Development of new products
- Simple production of higher alcohol products
Especially the last three items makes freeze concentration very interesting. Starting with regular wine by using freeze concentration can produce wines with any higher alcohol level in one single step keeping the original characteristics intact.
An additional advantage is often that the shelf life stability of the product improves.
The achievable alcohol concentration is 25 % alcohol by volume.
The concept of freeze concentration is explained in the chapter "Technologies" and "Documentation"
