The company was founded by Chris White, Ph.D, following years of research and devel-opment of a library of brewers yeast strains from around the world. Chris White received an undergraduate degree in Biochemistry from U.C. Davis, where his interest in brewing was inspired by Dr. Michael Lewis and Brewing and Malting Science courses. He began home-

brewing and relocated to San Diego for graduate studies in biochemistry. Chris’s doctoral thesis focused on developing high cell density growth techniques for an industrial yeast strain, Pichia pastorus. Because of his passion for craft brewing, Chris began to experiment, using the same high cell density growth techniques on brewers yeast. Chris developed a process to grow pitchable quantities of pure liquid brewers yeast. This innovation caught on quickly within the brewing community and White Labs yeast developed a strong word-of-mouth reputation. White Labs Yeast Culture Collection currently has over 500 deep frozen strains from around the globe. White Labs began providing one strain of yeast for one local San Diego homebrew shop, Homebrew Mart. Today, White Labs provides hundreds of yeast strains to breweries, wineries, distilleries, and homebrew retailers all over the world.

VodkaFErMENTATIoN AND SugAr SourCE

In the production of neutral vodkas, much depends on the selection of a suitable spirit, and the fermentation base of the spirit is less critical than the degree of purification achieved in distillation. In Russia, vodka is made from both grain and potato spirit; in the West, grain and molasses spirit are used. The selected spirits are diluted in alcoholic strength and subjected to treatment with activated carbon.

For potato vodka, potatoes must be cooked and gelatinized with as little water as possible, to maintain fluidity. Alpha amylase is added to keep liquid and Glucoamylase is used to liquefy product. Saccrafication takes place in approximately 30 minutes, and 100% gluclose is produced at 140ºF in a cooker. Another method is to add the enzyme directly to fermentation for a slower conversion. This “spoon fed” approach helps in avoiding a “glucose shock” effect of stressing the yeast. Cereal grains would use a similar process but would utilize varying gelatiniza-tion temperatures.

ginFErMENTATIoN AND SugAr SourCE

The production of alcohol is not an intrinsic part of the process of manufacturing gin, where a suitable high-quality spirit is selected and redistilled with flavoring materials or processed in some other way. Any material containing carbohydrate which can easily and economically be made available for fermentation can be considered as a suitable source material for spirit production. Materials rich in starch such as grain and potatoes will require a conversion to a more fermentable form while molasses possesses readily fermentable sugars.

The transformation of starch granules into a form that is capable of being fermented can be achieved by a number of methods. Tradition-ally done by enzymes, more modern plants utilize cooking the grain under conditions of elevated temperature and pressure to bring about starch gelatinization. The elevated temperatures and pressures ensure complete gelatinization and consequent higher spirit yield. At the ter-mination of cooking, the gelatinized starch is commonly blown down or discharged from the cooker at high pressures to aid in the break-down of large solids. The now fermentable sugars are then cooled to a temperature favoring amylolytic enzyme activity and mixed with an enzyme medium in a suitable conversion vessel. Commonly, separa-tion of wort from the grains does not take place after conversion, and the entire contents of the mash tun go forward to the fermenter and still. Enzymatic conversion is allowed to continue during fermenta-tion, leading to an improved attenuation and an enhancement of spirit yield.

Commercial enzyme preparations of α amylase and amyloglucosidase are available in liquid form and are replacing barley malt as the agent of conversion in grain and potato spirit distilleries. The α amylase may be substituted for pre-malt in the cooling stage.

TequilaFErMENTATIoN AND SugAr SourCE

The pine or head of the Agave tequilana plant is highly rich in carbo-hydrates, specifically inulin. Inulin is an oligosaccharide of fructose with a terminal glucose that belongs to the fructans - the most abun-dant non-structural polysaccharide found in nature after starch. Ad-junct sugars used in tequila wort formulation are analyzed for solids content, reducing and fermentable sugar content.

The amount of organoleptic compounds produced is higher in slow fermentations compared to more rapid fermentations. The rate of fermentation depends mainly on the yeast strain used, the medium composition (levels of fermentable sugars and yeast nutrients) and the temperature of fermentation. Significant losses in alcohol levels may occur if open fermenters are used.

Tequila fermentations are by no means classified as “fermentations carried out by pure yeast cultures.” Bacteria and wild yeast also play an active role in fermentation. Low levels of bacteria are welcomed as they tend to produce positive organoleptic properties and are attribut-ed to an overall complexity in the final product. The amount and variety are factors of the abundance of organisms introduced by the raw materials and the overall hygiene standards of the distillery.

Lactobacillus, Streptococcus, Leuconostoc, and Pediococcus are the most common bacteria, while Brettanomyces is also commonly encountered. A key point is the amounts of these organisms present. Fermentations overrun by bacteria will lower alcohol yields and pro-duce compounds, when at elevated levels, are considered off flavors.

Higher alcohols are closely associated with Tequila fermentations. Yeast strain, carbon:nitrogen ratio (higher ratios enhance higher alco-hol production) and temperature are the biggest factors.

rumFErMENTATIoN AND SugAr SourCE

For fermentation, concentrated molasses is cut with water to a gravity ranging from 20-25 brix. Cane juice on the other hand, with a sugar content of 12-16% w/ sucrose, can be used as is for fermentation.

Although abundant in fermentable sugars, any type of molasses or pure sugar fermentation medium is lacking in essential nutrients re-quired by the yeast for a healthy metabolism.

It does however, have a healthy population of bacteria and/or wild yeast that can take over fermentation, producing excess amounts of acetic a butyric acids which are toxic to yeast.

An acid addition is usually practiced to keep bacteria in check. Ad-ditionally excess salts and minerals can adversely affect yeast perfor-mance. A portion of dunder, the naturally fermented residue from a previous wash distillation, is normally pitched with a pure yeast culture for more complexity. Gentle aeration for the first 48 hours is beneficial for fermentation performance. Fermentation temperatures in the Caribbean can reach 90ºF, however lower temperatures (75-80ºF) will result in a better alcohol yield.

• *Blackstrap molasses (traditionally used for dark rums) • *High test molasses from evaporated cane juice (used for lighter rums) • *Refiners cane molasses

Bourbon WhiskeyFErMENTATIoN AND SugAr SourCE

In practice, bourbon mash is fermented “in grains” where the solids are not separated from the liquefied sugar solution. The maize and rye must be cooked before added to the mash containing malted barley in order that the starch in these grains can become exposed to malt enzymes.

The transformation of starch granules into a form that is capable of being fermented can be achieved by a number of methods. Tradition-ally done by enzymes, more modern plants utilize cooking the grain under conditions of elevated temperature and pressure to bring about starch gelatinization. The elevated temperatures and pressures ensure complete gelatinization and consequent higher spirit yield.

At the termination of cooking, the gelatinized starch is commonly blown down or discharged from the cooker at high pressures to a waiting mash tun already charged with malted barley and water. Cold water may be needed to achieve a conversion temperature of 60-65ºC for the enzymes to start their work on the now available starch.

rye WhiskeyFErMENTATIoN AND SugAr SourCE

In nature, starch exists in a tightly packed crystalline structure. Wa-ter is required to hydrolyze these starch granules into fermentable material. At specific temperature ranges the starch granules swell or gelatinize into a liquid phase. Enzymes present can now more eas-ily convert the high molecular weight carbohydrates into simpler fermentable sugars. The result is a substantial increase in viscosity. If suitable liquefaction enzymes are not present, the viscosity will overload most mechanical mixing systems. Pre gelatinized flakes are an option for those plants without adequate mashing temperature control.

Starch conversion can be achieved by the newer method of pressure cooking, however this requires specialized equipment and the inher-ent higher energy demand.

Rye grains, like wheat, do not have husks and therefore can be difficult to work with. Rye also is high in beta glucan, a gum like substance that tends to increase viscosities and cause transfer prob-lems.

Rye has also been known to cause excess foaming during fermenta-tion. Sufficient freeboard or the use of a non foaming agent may be necessary. Back set, a small amount from the previous ferment, is often added (25% of total fermenter volume) to the new ferment to assist in pH adjustment and with overall consistency of the prod-uct. Fermentation temperatures are normally held at 90-95ºF with slow, constant mixing.

Brandy FErMENTATIoN AND SugAr SourCE

Grape juices have distinctly varied properties conferred by their com-position. Tastes arising from the balances of organic acids, sugars and phenolic compounds; and aroma from a diverse mixture of secondary metabolites. This is typical of fruits. From the total amounts and bal-ance of sugars and organic acids, sweetness and sourness in fruit juices can be estimated.

Average grapes contain per 100g by weight: 6.2g gluclose, 6.7g fruc-tose, 1.8g sucrose, 1.9g maltose and 1.6g other mono and oligosac-charides.

In apples, sugars constitute between 7 and 14% of the fruit on a fresh weight basis, being almost entirely fructose, glucose and sucrose with traces of other sugars including xylose.

The soluble protein content of many fruit juices is very low and in apples is in the range of 10-250ppm but generally <100ppm. Amino acid contents juices decreases with storage.

Grape juices are typically between pH 3 and 4; apple juices near pH 3.

Carefully monitor the ph of many fruit mashes as high pH conditions are prone to bacterial infections.
