Selects and cultivates yeast cells to develop pure yeast culture for brewing beer and malt liquors

samples beer in fermenting stages to select specimens containing yeast cells having specific reproduction characteristics. Prepares cover glasses and slides with smears of yeast preparation taken from beer samples. Examines slides under microscope to isolate specific cells and record position of cells. Incubates slides to allow colonies of cells to form. Inoculates cells with hopped wort, using sterile needle to transfer cells from slides to flasks containing wort. Cultivates cells in flasks by incubation and propagates single cell cultures by transferring cells to additional flasks. Siphons developing yeast culture from flasks to tanks and pumps yeast culture from tanks to sterile barrels. Seals barrels with sterile bung and packs sealed barrels in dry ice to prevent yeast degeneration. Cleans and sterilizes equipment. [-] Less

Controls equipment to prepare mixture of mash and yeast for use in manufacture of distilled liquors

weighs specified quantities of rye and malt meal, depending upon amount of yeast required, and dumps them into yeast tub (cooker) filled with specified amount of water. Opens valves to admit steam that circulates through coil pipes in tub and cooks mixture. Starts revolving blades in tub to agitate mixture as it cooks. Observes temperature gauges and increases or decreases steam pressure to maintain constant temperature as mash cooks. Pours yeast culture into cooked mash and mixes mash with revolving blades. Stops revolving blades when mash and yeast are thoroughly mixed. Tests mash to determine temperature and specific gravity (proof), using thermometer and hydrometer, and records results. Observes gauges and increases or decreases steam to ensure that mash ferments at constant temperature. Notifies fermentation operator when mash is ready to be pumped into fermentation tank. Removes sample of mash for laboratory analysis. [-] Less

Tends power-driven pumps that transfer wort, beer, or liquefied yeast mixture to various sections of brewery

receives signal from point of destination indicating time of fluid transfer. Connects flexible hose and stationary lines to pumps and vessels containing specified fluid and notifies worker at destination point of line prior to transfer of fluid. Turns valves and starts pump to admit and control flow of liquid through lines. Collects random samples of fluid from vessels for laboratory testing, using beaker. May tend automated equipment to transfer liquids through various processes. May observe thermometers and turn valves to regulate flow of beer through refrigeration unit to maintain specified temperature of product cooling-machine operator. May pump two or more varieties of beer into one tank to blend mixture. May record types and amounts of beer pumped. May clean pumps and lines by flushing with cleansing solutions and water. May be designated according to plant location or product transferred as bottle-house pumper; cellar pumper; wort pumper; yeast pumper. [-] Less

Assists in the fermentation process by dumping chemical nutrients into yeast fermentation tanks to supplement diet of yeast cells. Takes samples of wort from tank for laboratory analysis. Cleans fermentation tanks, using steam and water. Transfers ingredients, materials, and finished products to production, storage, and shipping area, using hand trucks.

Tends equipment that washes, pasteurizes, and cools yeast cream (concentrated yeast suspension) used in manufacture of baker's yeast and yeast food

opens valve to pump yeast cream into tank, and adds water to yeast cream to remove traces of wort adhering to yeast cells. Pumps yeast cream and wash water to storage tank preparatory to centrifugal separation. Turns valves to admit steam into jacket of pasteurizer and circulate brine through cooling coils of cooler. Pumps yeast cream, that has been washed and separated from wash water, to pasteurizer and through cooling equipment to storage tank. Tests cream for acidity, using ph meter, and adds necessary chemicals to attain required acidity level. [-] Less
