Description

Verfahren zur Bestimmung-des Alterungsgrades von Spirituosen, insbesondere Weinbrand Die Erfindung -betrifft ein Verfahren zur Bestimmung des Alterungsgrades von Spirituosen, insbesondere Weinbrand, auch Met, Weinen u. dgl., und bezweckt die Ermöglichung einer einfachen objektiven Kontrolle des Fortschreitens der natürlichen, vor allem aber der künstlich beschleunigten Alterung sowie eine vergleichende Wertbestimmung von Spirituosen u. dgl.Method for determining the degree of aging of spirits, in particular Brandy The invention relates to a method for determining the degree of aging of spirits, especially brandy, also mead, wines and the like, and intended enabling simple objective control of the progression of the natural, but above all the artificially accelerated aging as well as a comparative valuation of spirits and the like

Erfindungsgemäß -wird entsprechend alkoholempfindliche, mit Gärsubstrat versetzte Testhefe mit der zu prüfenden Spirituose versetzt und die Abnahme der Gärintensität als Gradmeser für die Lebensäußerung beobachtet. .Dies kann in an sich bekannter Weise durch Beobachtung bzw. Messung der entwickelten Kohlensäure, Abnahme des Zuckers im Substrat usw. geschehen. Man kann das Verfahren leicht derart ausüben, daß man der Testhefe unter dem Mikroskop die zu prüfende Spirituose ,in kleinen Mengen so lange zusetzt, bis die Gärtätigkeit erlahmt, was durch Auszählung. der Kohlensäurebläschen beispielsweise feststellbar- ist. Auf dem Wege über Tierversuche ergab sich empirisch, daß diese Ermittlung am einfachsten unter Benutzung von einer der bei der ursprünglichen Gärung der Ausgangsstoffe wirksamen ähnlichen, aber alkoholempfindlicheren Heferasse - die eigens dafür angestellt wird -. gelingt.According to the invention -is correspondingly alcohol-sensitive, with fermentation substrate spiked test yeast spiked with the spirit to be tested and the decrease of the Fermentation intensity as a measure of the expression of life observed. .This can be done in known way by observing or measuring the carbon dioxide developed, Decrease in sugar in the substrate, etc. happen. One can do the procedure easily like that exercise that the test yeast under the microscope the spirit to be tested, in Adds small amounts until the fermentation slows down, which is done by counting. the carbonic acid bubbles can be detected, for example. On the way via animal experiments it has been found empirically that this determination is easiest using a the similar, but more sensitive to alcohol, effective in the original fermentation of the raw materials Heferasse - which is specially employed for this purpose -. succeed.

Es ist klar, daß man bei Prüfung von hochalkoholhaltigen Spirituosen solche Hefesorten benutzt, welche vergleichsweise alkoholunempfindlich sind, während umgekehrt bei Prüfung schwach alkoholischer Spirituosen auch alkoholempfindliche Rassen verwendet werden sollen, weil die Empfindlichkeit der Hefen gegen Äthylalkohol mit der Empfindlichkeit gegen diejenigen Begleitstoffe zunimmt, deren Art und Menge für den Alterungsgrad maßgebend ist. An Stelle. von Hefe können auch andere niedere Lebewesen verwendet werden, die jedoch wegen ihrer großen Empfindlichkeit meist schwieriger zu handhaben sind.It is clear that when testing high alcohol spirits one is concerned those yeasts used, which are comparatively insensitive to alcohol, while conversely, when testing weakly alcoholic spirits, also alcohol-sensitive ones Breeds should be used because of the sensitivity of yeasts to ethyl alcohol with the sensitivity to those accompanying substances, their type and amount increases is decisive for the degree of aging. Instead of. of yeast can also be other lower Living beings are used, however, mostly because of their great sensitivity are more difficult to handle.

Eine vergleichende Wertbestimmung mit Hilfe von Testhefe ergab beispielsweise für einen handelsüblichen Weinbrandverschnitt die Alterungszahl 25, für den entsprechenden Weinbrand nach künstlicher Alterung gemäß dem Verfahren der Patentschrift 549 524 die Zahl 8o im Vergleich mit einem etwa 40jährigen, natürlich gealterten französischen Proprietärkognak, welchem willkürlich die Zahl ioo zugrunde gelegt wurde. Unmittelbar qualitative und quantitative Rückschlüsse auf die Bekömmlichkeit und die Veredelung der Geschmackseigenschaften haben sich in der Praxis als zuverlässig erwiesen.A comparative value determination with the help of test yeast resulted, for example For a commercial blend of brandy the aging number is 25, for the corresponding one Brandy after artificial aging according to the method of patent specification 549 524 the number 8o in comparison with a naturally aged French woman around 40 years old Proprietary cognac, which was arbitrarily based on the number ioo. Direct qualitative and quantitative conclusions on the digestibility and the refinement the taste properties have proven to be reliable in practice.
