Coolship
A coolship (Anglicized version of the Dutch/Flemish koelschip) is a type of brewing vessel traditionally used in the production of beer. It is a broad, open-top, flat vessel in which wort cools. The high surface-to-mass ratio allows for more efficient cooling. Contemporary usage includes any open fermentor used in the production of beer, even when using modern mechanical cooling techniques. Traditionally, coolships were constructed of wood, but later were lined with iron or copper for better thermal conductivity. The word "coolship" was trademarked by Allagash Brewing Company in the United States. The company later decided to terminate the trademark, in the interests of maintaining good relations with others in the craft beer industry.

Wort
Wort () is the liquid extracted from the mashing process during the brewing of beer or whisky. Wort contains the sugars, the most important being maltose and maltotriose, that will be fermented by the brewing yeast to produce alcohol. Wort also contains crucial amino acids to provide nitrogen to the yeast as well as more complex proteins contributing to beer head retention and flavour. Production The first step in wort production is to obtain malt, which is made from dried, sprouted cereal grains, including barley. The malt is run through a mill, cracking the husk and exposing the starch inside. The milled grain is then mashed by mixing it with hot water, and then steeped, a process that enables enzymes to convert the starch in the malt into sugars which dissolve in the water. Sometimes the mash is heated at set intervals to alter the enzyme activity. The temperature of the mixture is usually increased to 78 °C (172 °F) for mashout. Lautering is the next s ...

Thermal Conductivity
The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by k, \lambda, or \kappa. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity. For instance, metals typically have high thermal conductivity and are very efficient at conducting heat, while the opposite is true for insulating materials like Rockwool or Styrofoam. Correspondingly, materials of high thermal conductivity are widely used in heat sink applications, and materials of low thermal conductivity are used as thermal insulation. The reciprocal of thermal conductivity is called thermal resistivity. The defining equation for thermal conductivity is \mathbf = - k \nabla T, where \mathbf is the heat flux, k is the thermal conductivity, and \nabla T is the temperature gradient. This is known as Fourier's Law for heat conduction. Although commonly expressed as a scalar, the most general form of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allagash Brewing Company
__NOTOC__ Allagash Brewing Company is a brewery in Portland, Maine. The brewery specializes in Belgian style beers. History The brewery was founded in 1995 by Rob Tod in Portland, Maine. He observed that while both German and British style beers were available throughout the United States, Belgian-style beers were difficult to find. He established a small, 15-barrel brewery, and began brewing a beer modeled after a Belgian Wit beer, named Allagash White. The beer gets its flavor from the use of wheat in place of barley, as well as the addition of Curaçao orange peel, coriander, and other spices. All of the beers Allagash produces are bottle conditioned. The technique calls for two fermentations, the first in the fermenting tanks and the second in the bottle itself (a process known as the ''methode champenoise''). A coolship is used to cool the wort for some of the beers. Allagash was one of the first breweries in the US to build a traditional coolship for spontaneous ferme ...

Lambic
Lambic () is a type of beer brewed in the Pajottenland region of Belgium southwest of Brussels and in Brussels itself since the 13th century. Types of lambic beers include gueuze, kriek lambic and framboise. Lambic differs from most other beers in that it is fermented through exposure to wild yeasts and bacteria native to the Zenne valley, as opposed to exposure to carefully cultivated strains of brewer's yeast. This process gives the beer its distinctive flavour: dry, vinous, and cidery, often with a tart aftertaste. Etymology This beverage is first mentioned in 1794 as ''allambique''. The initial 'a' was dropped early on, so that in an 1811 advert it was called ''lambicq'', though it was sometimes referred to as ''alambic'' as late as 1829. The name may stem from alembic, a type of still used for producing local spirits like cognac and jenever (but not used in the production of lambic). Breweries in and around Lembeek, a village near Halle, Belgium, have attempted to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
