On Sunday, 20 January 2008, Professor Langnickel and his wife entered Le Lion in Hamburg. They were seated at table 20, the first table on the left as seen from the bar. They wanted something with brandy or sherry and asked for a recommendation from Mario Kappes, who has a preference for Spanish brandy and sherry, and he first served his Don Raphael, which consists of just these two main ingredients. This drink was well received and the conversation started. More drinks with sherry followed. But at some point Mario ran out of recipes, and finally this moment happened: a new, great drink was born. [1] [3] [4] [5]

According to Mario, he first put the sherry in a mixing glass, smelled it, tasted some of it too and had the inspiration to combine cherry with it. A cherry that must come with it rich and sweet. He added the Guignolet, but the result was still not quite convincing, as the cherry did not stand up to the sherry. A link in the form of a high-proof alcohol was missing. At first, he thought of common spirits like gin, rum, or something unaged. But now there was also a bottle of kirsch. Until then, it had not been common practice for Mario to mix with eau de vie. But since he wanted to bring the cherry flavours to the fore, it was obvious to choose the kirsch. [5]

The moment Mario started preparing, Jörg Meyer looked over his shoulder, saw the bottle of Morand Kirschwasser and Guignolet and combined that the next drink would probably be a “Dr Sack”. [1] [3] [4] [5] Since it fits well with this story, we would therefore like to take a short excursion here and report on the “Dr. Sack”.

Jörg Meyer had become acquainted with this drink in the Old Fashioned Bar in Hamburg, where it was prepared by Achim F. Eberhardt. The latter stated that at the Adlon Hotel in Berlin there had been a regular called “Dr Sack” who always ordered an ice-cold stirred drink made of one third each of kirsch, cherry brandy and gin. At some point, this mixture would also have been called “Dr. Sack” by the bartenders of the hotel. As Jörg reports, it is a rarely encountered drink. He had only seen it in the Old Fashioned Bar and on some old recipe lists of the German Bartenders’ Union. It is a difficult drink to handle because it only works with the right cherry eau de vie and the right cherry liqueur. [1] [5]

Therefore, we have not come across “Dr. Sack” in old books, which may have something to do with the fact that the drink was only renamed “Dr. Sack” by the bartenders at the Adlon. One can assume that the drink was not developed for Dr. Sack, but was only ordered by him. This thesis is based on our findings in the old books. The mixture of equal parts of cherry eau de vie, cherry brandy and gin can be found in 1935 in the book “The Barkeeper’s Golden Book” published in Zurich under the name “Baimaster”. In the same book, a mixture of two parts gin and one part each cherry brandy and kirsch can be found under the name “Rose Swiss”, and a year earlier in the book “Gordon’s Cocktail and Food Recipes” published in Boston, the “Francaise Rouge” is made from two parts gin and one part each cherry brandy and kirsch. Another curiosity is the 60° cocktail from 1947, which also uses two dashes of Kümmel.

As Jörg Meyer reports, based on his observation, he asked „Oh … a Dr. Sack?“, but this was not known to Mario Kappes and the conversation continued with „Dr. Sack? Nah, I don’t know that one…“„Okay, so what are you mixing then?“„I’d like to give Mr Langnickel another sherry drink, I have an idea, but I’m not sure if it will work“. Mario stirred the drink, poured it into the glass and realised that it was a very demanding drink that needed a little binder in the form of a lemon zest. [1] [5]

At this point we would like to quote Jörg Meyer, because he describes the result very aptly: “Mario put the three ingredients, 2 cl PX sherry, 2 cl Guignolet de Dijon/Gabriel Boudier and a good 4 cl Morand cherry brandy into the mixing glass, stirred vigorously, strained into the pre-chilled cocktail glass and added a lemon zest over and into the drink. Mr Langnickel was thrilled! He had to mix a second one immediately and we tasted it: Incredibly complex! Kirsch, pleasantly reduced to drinking strength but clearly tasted. The liqueur miracle from Dijon unfolded a wonderful cherry flavour without even a hint of sweetness. The PX came at the very end, though still a little delicate, almost plummy, it made for a long finish. We changed two things in the next “Langnickel” and both think we have found a perfect recipe. The lemon zest was only squeezed over the drink and no longer added. Instead, there were 3 real Maraska cherries preserved in cherry brandy and Maraschino, which went perfectly with the drink. Secondly, we reduced the cherry brandy by 1 cl to create a perfect harmony of the three ingredients.[1] [4]

– „Mario gab die drei Zutaten, 2 cl PX Sherry, 2 cl Guignolet de Dijon/Gabriel Boudier und gut 4 cl Morand Kirschbrand ins Rührglas, rührte kräftig, seihte ins vorgekühlte Cocktailglas ab und gab eine Zitronenzeste über und in den Drink. Herr Langnickel war begeistert! Er musste sofort einen zweiten mixen und wir probierten: Unglaublich komplex! Kirschwasser, angenehm auf Trinkstärke herabgesetzt aber deutlich zu schmecken. Das Likörwunder aus Dijon entfaltete einen wunderbaren Kirschgeschmack ohne auch nur einen Hauch von Süß zu sein. Der PX kam ganz zum Schluss, wenn auch noch ein wenig zart, fast pflaumig, sorgte er für einen langen Abgang. Wir änderten beim nächsten „Langnickel“ zwei Dinge und sind Beide der Meinung, damit ein perfektes Rezept gefunden zu haben. Die Zitronenzeste wurde nur noch über dem Drink abgespritzt und nicht mehr hinein gegeben. Statt dessen gab es 3 echte in Kirschbrand und Maraschino eingelegte Maraska-Kirschen die perfekt zum Drink passten. Zum anderen reduzierten wir den Kirschbrand um 1 cl um es kam zu einer perfekten Harmonie der drei Zutaten.“ [1] [4]

Like the “Dr. Sack”, this drink only works with the right cherry eu de vie and the right cherry liqueur. [1]

Mario Kappes says of the ‘Professor Langnickel’: “But I soon realised that you have to explain this drink in advance. If the guest reads cherry and is looking forward to a relaxed fruit bomb, it will be difficult.” The guignolet is important in the preparation, because: “Any other cherry liqueur won’t work, at least none that I’ve tried. Boudier’s Guignolet de Dijon is the least interchangeable of the whole construct. The distillate, in turn, must be a clear, distinct cherry distillate as a counterbalance, definitely one without juice or sweetener content. The drink won’t work with spirits that are too fruit-dominated.” A cherry distillate was chosen because “if you mix cherry liqueur and PX sherry with whiskey or rum, the result is a uniform mash. Then the drink is no longer differentiated.” Mario adds: “I’m not really a fan of zesting everywhere. But this drink needs it. The lemon zest helps the overall fruitiness. Without it, the drink can get very sweet and tiring as it warms up. We even partially re-zested a second time at that point.[6]

– »Mir war aber bald klar, dass man diesen Drink im Vorfeld erklären muss. Wenn der Gast Kirsche liest und sich auf eine entspannte Fruchtbombe freut, wird es schwierig.“ „Jeder andere Kirschlikör funktioniert nicht, zumindest keiner, den ich ausprobiert habe. Der Guignolet de Dijon von Boudier ist am gesamten Konstrukt am wenigsten austauschbar. Das Destillat wiederum muss als Gegengewicht ein klares, eindeutiges Kirschdestillat sein, auf jeden Fall eines ohne Saft oder Süßungsanteil. Mit zu fruchtdominierten Spirituosen funktioniert der Drink nicht.« »Wenn man Kirschlikör und PX Sherry mit Whiskey oder Rum mischt, ist das Ergebnis ein Einheitsbrei. Dann ist der Drink nicht mehr differenziert.« »Ich bin eigentlich kein Freund davon, überall zu zesten. Aber dieser Drink braucht es. Die Zitronenzeste hilft der gesamten Fruchtigkeit. Ohne sie kann der Drink sehr süß und anstrengend werden, wenn er sich erwärmt. Wir haben damals teilweise sogar ein zweites Mal nachgezestet.« [6]

But now we come to the name. The drink didn’t have one yet, but it quickly became clear that it could only be named after the guest. The guest was Professor Langnickel from Cologne, who had been running the Barfly Cocktailbar there for years with his wife Anne. He is a professor of sociology and neither of them had anything to do with gastronomy originally. However, they were both so fascinated by bar culture, the associated drinks and stories that they decided to open their own bar. [1] [3] [4] [5]

After Jörg had originally thought of a “Dr. Sack” and now – in our opinion – a much better drink, a “Dr. Sack 2.0”, so to speak, had been created, it made sense to turn the “Dr.” into a “Professor” and to name the drink after the guest for whom it had been created. [3]

Hi, I'm Armin and in my spare time I want to promote bar culture as a blogger, freelance journalist and Bildungstrinker (you want to know what the latter is? Then check out "About us"). My focus is on researching the history of mixed drinks. If I have ever left out a source you know of, and you think it should be considered, I look forward to hearing about it from you to learn something new. English is not my first language, but I hope that the translated texts are easy to understand. If there is any incomprehensibility, please let me know so that I can improve it.
