Dextrinizing units (DU)
Dextrinizing units (DU) or alpha-amylase: While DP gives a ratio for all amylases present in the malt, DU breaks out alpha-amylase. A range of 35-50 DU (dextrinizing units) is acceptable, depending on the malt type and the mash program. Munich malt may be below 10, and pale malts may be as low as 25.
PVC (polyvinyl chloride)
Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.
PVC (polyvinyl chloride) is a common, low-cost plastic used in tens of thousands of products including plastic wrappers, vinyl fabrics, paint, pipes, and siding. It's all around us. Without additives or contaminants, pure PVC is actually non-toxic, but when turned into products, it's almost exclusively combined with chemicals and plasticizers. These combinations make it bad stuff for us and the planet.
When PVC is manufactured, it produces potent carcinogens and toxins including dioxins, chlorine residue, and heavy-metal pollutants. Over their lifespan, PVC products can off-gas and leak dangerous additives. PVC is also difficult to recycle; most of it ends up in landfills. When burned, it releases further dioxins and gases such as hydrogen chloride.
PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used for bottles, other non-food packaging, and cards (such as bank or membership cards). It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is also used in plumbing, electrical cable insulation, imitation leather, signage, inflatable products, and many applications where it replaces rubber.
Pure poly(vinyl chloride) is a white, brittle solid. It is insoluble in alcohol but slightly soluble in tetrahydrofuran.
ppm (parts per million)
ppm - parts per million - is commonly used as unit of concentration and equivalent to milligrams per liter (mg/l)
parts per million - ppm - is commonly used as a measure of small levels of pollutants in air, water, body fluids, etc. Parts per million is the mass ratio between the pollutant component and the solution and ppm is defined as
ppm = 1,000,000 mc / ms (1)
where
mc = mass of component (kg, lbm)
ms = mass of solution (kg, lbm)
In the metric system ppm can be expressed in terms of milligram versus kg where
1 mg/kg = 1 part per million
ppm can be also be expressed as:
1 ppm = 0.0001 %
1 000 ppm = 0.1 %
10 000 ppm = 1%
Dry Stout
Die bekanntesten Stouts auf der Welt sind Dry Stouts. Diese sind von herbem Charakter, tiefschwarz in Farbe, mit vollmundigem Aroma und cremigem Schaum und kommen aus Irland. Die bekanntesten irischen Dry Stouts sind Guinness, Beamish und Murphy. Gute Dry Stouts werden natürlich auch außerhalb Irlands gebraut, sind jedoch lang nicht so bekannt.
Deuteronomy Brewery 1426
The home brewery founded by Jake McWhirter. The name of the brewery is a reference to Deuteronomy 14:26 in the bible where God tells His people to buy alcoholic drink and enjoy it while worshiping Him. The motto of the brewery is "Fine Beer Brewed to the Glory of God".
