Abstract
The Practical Brewer, 3rd edition (p. 248), contains a paragraph on
abnormal fermentations. Within this section, some common causes of abnormal
fermentations are described, and peculiarities are discussed. The intent of this
paper is to provide insight into one very specific type of abnormality that has
been observed and studied in the field�stratified fermentation. This abnormal
fermentation has been seen in large and small breweries and has been reported to
the author as occurring in a university pilot brewery. All specific data
presented are from an original report by the author and his team when
stratification was found, documented, and corrected in their brewery�s 4,800-bbl
fermentors.
Keywords: abnormal fermentations, multibrew fermentors, stratified
fermentors
S�ntesis
El Practical Brewer, 3a edici�n (p. 248), contiene un p�rrafo sobre
fermentaciones anormales. Se describen algunas causas comunes para
fermentaciones anormales y se discute sus peculiaridades. Este art�culo intenta
dar luces sobre un tipo espec�fico de anormalidad que ha sido observada y
estudiada en escala industrial�la fermentaci�n estratificada. Esta anormalidad
ha sido observada en cervecer�as peque�as y grandes, como tambi�n en una planta
piloto cervecera en una universidad. Todos los datos en este art�culo fueron
tomados del reporte original de este autor y su equipo cuando se observ�,
document� y corrigi� una estratificaci�n en las fermentadoras de su cervecer�a
de 5,600 hL.
Palabras claves: fermentaciones anormales, fermentadoras estratificadas,
fermentadoras para m�ltiples cocimientos
