Many people experience an occasional glass of wine with
dinner, however after a tumbler or , what do you do with the rest of the
bottle? once opened, wine at once starts offevolved to react with the air and
damage, so how can you keep away from ruining your favorite vintage?
Now, a employer called Kuvée has designed a device that it
says can maintain wine sparkling for as much as 30 days, and possibly even
longer.
What makes opened wine taste terrible after just a few days?
The culprit is oxygen, scientists say. As quickly as you pull out a cork, air
floods the bottle, displacing the gas that turned into trapped inner. fresh air
contains oxygen that is absorbed by means of the wine over the next few days.
Oxygen reacts with phenolic compounds, the chemicals that produce wine’s taste
and aroma. those reactions, called oxidation, trade the chemical shape of the
phenolic compounds, dulling and flattening the flavor and scent of the wine.

Kuvée (pronounced "koo-vay,"after the French word
for a unique allotment of wine) has created a bottle which can help wine stay
sparkling, by preserving air out, according to the business enterprise.
The Kuvée is a -element machine: a sealed capsule that shops
the wine and a hollow sheath that is used to pour. when the tablet is inserted
into the Kuvée bottle, it seems and feels similar to a general wine bottle. And
that became an intentional a part of the layout, said Ed Tekeian, leader
technical officer for Kuvée.
“We desired to have some thing that pours like a bottle of
wine – as opposed to a coffee maker that sits on your countertop,” Tekeian
informed live technological know-how.
the important thing to the Kuvée machine is a patented,
multistage valve in the neck of the capsule that replaces the cork. An outer,
sealed valve opens most effective when a pin inside the Kuvée bottle punctures
it. The valve reseals when the tablet is removed from the bottle, the
enterprise stated.
For the inner valve, the Kuvée team borrowed an idea that is
extra normally located in scientific technology. This so-called "test
valve," often used in dialysis device, only allows liquid to float in a
single route, proscribing what can skip in reverse. when the bottle is tipped to
pour, wine places stress on a flap inside the valve, pushing it open so that
wine can flow out, the organisation stated. but when the bottle is upright, the
flap is tightly closed, stopping air from entering the bottle.
"The Kuvée bottle is in no way genuinely open," so
less than 0.1 grams of oxygen enters the bottle as the wine pours, Tekeian
stated. And he has the statistics to back up his claims. The Kuvée studies
group measured the accumulation of dissolved oxygen in wine over time and the
decline of a chemical called sulfur dioxide, which suggests how a whole lot
oxidation has came about. Sommeliers also evaluated the same samples, he
stated. at the give up of 30 days, the wine in a Kuvée bottle is comparable in
each chemical makeup and flavor to wine that has been in a widespread corked
bottle for three days, in keeping with Tekeian.
The Kuvée bottle comes geared up with a full coloration
screen so that you can study more about the wine you are ingesting. The
wireless-enabled "smart" bottle also allows you to reserve extra
wine, offer remarks approximately your possibilities, and obtain tips about
different wines you would possibly experience. The Kuvée bottle and 4 bottles
of wine are available for $199 through pre-orders on the employer’s website. extra
bottles of wine can be bought at their regular retail fee ($15 – $50), and
orders will begin delivery in October to California and Massachusetts, the
employer stated.

accurate the quantity of oxygen that enters the bottle because the wine pours,
and to adjust the predicted shipping date.
