I've never heard of this, came in the email newsletter from a LHBS.
Wondering if anyone has tried these juice buckets:
"For the past two decades, the Flash Détente method of extraction has been used in Italy, France, South America, and Australia and is rapidly becoming mainstream in the American wine industry. Flash Détente is a device used to extract color and flavor from wine grapes using extreme heat, followed by rapid cooling
in a vacuum chamber, literally exploding the grape and the cell walls that contain the anthocyanins and flavor compounds. The fruit is de-stemmed and tightly crushed to create liquid must which is pumped into holding tanks where approximately 400 gallons of the juice is separated from the must to form a “juice ring”. This ring is heated to 200 degrees ferenheit and circulated continuously. Once temperature of the juice is achieved the solids are blended with the ring to be heated rapidly. The hot skins are then delivered to the vacuum tank
where they are immediately flashed. The vacuum will create steam that is removed through condensation cooling the must down to 85 degrees and pulling out flash water containing off flavors. (A full truck 24 ton load will take approximately four hours to process.) During the process 3-5% of the volume is blown off in the form of steam. This loss of water will increase the sugar content in the juice concentrating the flavors and can create a thicker, more complex wine. The steam that is blown off is comprised of water (flash water) containing the heaviest molecules having the longest flavor chains. These long chain molecules are the least desirable in that they are typically comprised of methoxy-pyrazines which are the vegetal, green bell pepper, and asparagus
flavors. During the rapid heating and cooling process problematic microbes and proteins such as brettanocyces, acetobacer, and laccase caused by rot or mildew are eliminated or denatured leaving the juice virtually sterile.
We have several 6 gallon buckets of Lodi Old Vine Zinfandel that has gone through the Flash Détente process for sale at $84 per 6 gallon bucket. This juice will make a wine that has superior flavor than regular juice and all the color of grape wine."
