The impact on the development of turbidity from chilling lager-style beer at constant low temperatures and alternating to low temperatures has been investigated. Irrespective of whether a beer is held isothermally or has received a change in temperature of storage, the magnitude of the haze that develops is determined by the extent of chilling that the beer encounters. Equally, the length of storing a beer at a prior, higher temperature does not influence the extent of haze development when the beer is subsequently brought to a lower temperature. These observations support the contention that in the formation of insoluble material during cold conditioning of beer, a short period at a very low temperature (e.g., –2.5°C) is more efficacious than a prolonged period at a warmer temperature (e.g., 0°C). Keywords: Haze, Stabilization


La Importancia Relativa de Temperatura y Tiempo en el Acondicionamiento Frío de Cerveza

El impacto en el desarrollo de turbiedad causado por el enfriamiento de cerveza estilo lager a temperaturas bajas constantes y alternación a temperaturas bajas se investigo. Independiente de si una cerveza está sostenida isotérmicamente o ha recibido un cambio en temperatura de almacenaje, la magnitud de calina que se desarrolla es determinada por el grado de enfriamiento que la cerveza llevó. Igualmente, la longitud de almacenar una cerveza a una temperatura anterior más alta no influye el grado de desarrollo de calina cuando la cerveza se lleva posteriormente a una temperatura más baja. Estas observaciones apoyan la contención que en la formación de material insoluble durante el acondicionamiento frío de cerveza, un período corto a una temperatura muy baja (e.g., –2.5°C) es más eficaz que un período prolongado a una temperatura de mas calor (e.g., 0°C). Palabras claves: Calina, Estabilización
