A wine glass is never neutral, and Josephinenhütte has built an entire philosophy around that idea: The Shape of Taste. At its center is the Josephine collection’s signature bend, a calculated form Kurt Josef Zalto spent 30 years refining through hundreds of prototypes. Mouth blown by hand, each of the ten shapes acts as a stage, letting a wine’s true character unfold without distortion or compromise.
The shape of taste
A wine glass is never neutral. Shape, material, size, every dimension of it works on the wine inside, guiding which aromas rise first, how the texture lands on the tongue, which characteristics of a wine are emphasized and which recede. Most glassware treats this as incidental. Josephinenhütte has made it the entire premise of the brand, and given it a name: The Shape of Taste.
At the center of that philosophy is the Josephine collection, and at the center of the Josephine is a series of careful design decisions, the most striking of which is the calculated bend in the bowl, that took its designer the better part of a career to arrive at. Kurt Josef Zalto has spent more than thirty years studying how the architecture of a glass changes the behavior of the wine inside it. “I have been exploring the influence of shapes and materials on the behavior and taste of wines for over 30 years,” he has said. “Like the great masters of the Renaissance, I adhere to the concept of calculated form. It takes a great deal of time and intuition for me to develop the shape and function of the glass until the individual radii and angles are in perfect harmony. The result is a highly functional design that is also aesthetically compelling.”
Calculated form is the right phrase, because nothing about the Josephine was left to chance. Several hundred prototypes were built and discarded before Kurt Zalto found the proportions he was after. The height to diameter ratio of each bowl, the precise curve of its contour, the sharply tapered base beneath the stem, every element was tuned in relation to the others, in service of a single outcome: the fullest possible unfolding of a wine’s aroma, weight, and flavor, together, in the order the wine itself intends. Notably the bend in the bowl, the signature kink at the heart of the Josephine design, plays a functional role. It acts almost like a wave breaker when the wine is swirled, pulling oxygen into the wine and letting it open inside the bowl rather than sitting flat against the glass. Josephinenhütte describes the effect simply: the glass becomes a stage, and the wine tells its story on it, clearly and without distortion.

Every Josephine is mouth blown and shaped entirely by hand, a process that unfolds over several days and depends on four to six master glassmakers working in sequence on a single piece. It begins with a specific glass composition, melted at temperatures above 1,400 degrees along a temperature curve so sensitive to outside conditions that a Josephine is made on days when the weather, air pressure, and furnace align to produce the quality the design requires. An artisan draws molten glass from the furnace and shapes it by feel into what is called the blob, working entirely by instinct and experience, since a difference of as little as ten grams of glass can be the difference between the lightness the Josephine is known for and a glass that misses the mark.
From there the glassblower forms the bowl, known as the cuppa, by continuously rotating the pipe and blowing the molten glass into a two part mold. At nearly 1,000 degrees, the glass floats inside the mold on a barrier of steam without ever touching it, a technique that only the most experienced glassblowers can execute on a shape as thin walled and angular as the Josephine. A master glassmaker then pulls the stem directly from the same piece of glass as the bowl, shaping it by eye with nothing more than a pair of tongs, so that bowl and stem are one continuous form rather than two pieces joined together. A second master shapes the base, applying a single drop of molten glass and forming it into a perfectly flat plate using a wooden foot cutter, judged entirely by hand and by eye.
The finished piece is then cooled slowly, over several hours, from roughly 520 degrees down to a comfortable hand temperature, a gradual descent that gives the glass an unexpected resilience for something so delicate. The cap is removed with a diamond tipped score and a 1,600 degree flame, the rim is ground to remove any sharpness, and finally the glass passes through a flame channel for fire polishing, the step that leaves the rim soft and almost weightless against the lip. Any glass that falls short of the standard at any stage is melted down and never leaves the workshop.

The result of all that calculation and all that handwork is a glass that does not announce itself. It disappears in the hand and lets the wine take over, which is precisely the experience that has converted some of the most discerning palates in the wine world.
André Hueston Mack, the sommelier, winemaker, and owner of &Sons in Brooklyn, describes his own first encounter with the Josephine as a turning point in how he thought about wine altogether.
“It was the tactile experience that truly elevated my wine drinking. The lightness, the precision, and the seamless delivery of the wine, it all came together in a way that was genuinely transformative.”

Nikita Malhotra, New York’s Best Sommelier in 2022 and owner of Smithereens, sees the same idea from the other side of the glass, as the person responsible for choosing what guests drink from.
“Form and function are fully recognized in a Josephinenhütte glass, and that ability to communicate through the design of a glass is quite an achievement.”
— Nikita Malhotra, Owner and Sommelier, Smithereens, New York
That is the whole purpose of the Josephine, ten times over across its range. Not a glass that flatters a wine or imposes a style on it, but one precise enough, and honest enough, to let every wine arrive exactly as it was made to taste.

From the No. 1 White through the No. 10 Eau de Vie, and across the decanters and carafes that complete the range, every Josephine carries the same engineered bend in the bowl, the signature kink that gives the collection its character and its function alike. The conviction behind it all, in Kurt Josef Zalto’s own words, is calculated form: a shape resolved through years of intuition that finally lets a wine speak for itself.
