Introduction to Beverage Science

Course Description

Introduction to Beverage Science is an introduction to the science of fermentation to produce beverages including yeast propagation, harvesting and management in a professional brewery setting. Students manage yeast used to brew commercial quantities of beer.

Within the SCNS taxonomy, HFT is the Hospitality Management prefix. Daytona State publishes this at 3 credits, offered fall, giving approximately 45 contact hours at the prefix convention.

This is the most technical course in the hospitality prefix, and its subject is narrower and deeper than the title suggests: it is essentially a course in applied yeast management. That focus is well judged, because yeast is the variable that most determines whether a commercial beer is consistent. Recipes are easy to copy; a healthy, correctly pitched, correctly repitched yeast culture is what a brewery's quality actually rests on, and it is where small breweries most often fail.

Daytona State does not publish a lecture and laboratory split for its HFT courses, but the convention across the prefix is consistent: every unsuffixed HFT course published at this institution runs at 3 credits and approximately 45 contact hours — 15 hours per credit, confirmed across twelve live courses without exception. The prefix's two C-suffixed courses (HFT2750C and HFT2867C) run at 20 hours per credit, which is what the suffix signals.

Special Information

⚠ Aseptic technique is the whole discipline — and it is a laboratory skill, not a kitchen one

• Yeast propagation is microbiology. You are growing one organism deliberately while excluding every other one, and a single contaminated propagation can infect an entire brewery through repitching.
• Work clean, work fast, and work in still air. Flame or a laminar flow hood, sanitised surfaces, and no unnecessary movement.
• Never touch anything that will contact the culture. Lips of vessels, inner surfaces of caps, and the working end of any implement.
• One contamination event compounds. Repitching propagates the infection forward through every subsequent batch, which is why breweries discard cultures on a schedule rather than when a problem is visible.
• Trust the microscope, not the taste. By the time contamination is obvious in the finished beer, several batches are affected.
• Label every culture with strain, generation, date, and source — an unlabelled culture is an unusable culture.
• Track generations and set a limit. Yeast performance degrades with repitching, and mutation accumulates.
• Keep a clean master stock you can always return to.

⚠ Yeast management is where consistency is won or lost

• Pitch rate is not approximate. Under-pitching stresses yeast and produces off-flavours; over-pitching produces thin, characterless beer. Calculate it every time rather than estimating.
• Viability and vitality are different things. A culture can be mostly alive and still perform poorly — measure both.
• Oxygenate the wort, not the beer. Yeast needs oxygen at pitching to build cell membranes; oxygen after fermentation is a defect.
• Temperature control produces flavour. The fermentation profile is a recipe ingredient, and letting it drift changes the product.
• Do not harvest from a stressed or infected fermentation, however inconvenient.
• Measure and record every fermentation — the data set is what lets you diagnose the batch that goes wrong.
• A stuck fermentation has a small number of causes — pitch rate, nutrients, oxygen, temperature, and wort composition. Work through them systematically rather than guessing.
• Yeast is a living culture with a cost. Managing it well is one of the clearest efficiency gains available to a small brewery.

⚠⚠ Brewery hazards — a production facility, not a kitchen

• A commercial brewery is an industrial environment with hazards that a hospitality background does not prepare anyone for, and the serious incidents in craft brewing are consistent and well documented.
• ⚠⚠ Carbon dioxide is the one that kills. CO₂ is heavier than air, odourless, and collects in cellars, tanks, and low spaces. It displaces oxygen and people lose consciousness without warning. Monitors, ventilation, and never entering a confined space alone are not optional.
• Confined space entry — tanks and vessels — requires a permit, testing, and a trained attendant. Vessel entry has killed brewery workers, including experienced ones. Never enter a tank because it seems fine.
• Caustic and acid cleaning chemicals cause severe burns. Full personal protective equipment, correct dilution order, and never mixing chemistries — and know where the eyewash and shower are before you need them.
• Hot liquor, steam, and wort cause serious scalds. Mash and boil vessels operate at temperatures that injure instantly.
• Pressurised vessels and kegs store real energy. A keg is a pressure vessel; treat relief valves and gauges as safety-critical.
• Wet floors, hoses, and heavy lifting cause the everyday injuries — grain sacks, kegs, and pallet handling all need technique and equipment.
• Lockout-tagout applies to pumps, mills, and conveyors.
• Grain dust is combustible in sufficient concentration, and milling areas need appropriate controls.
• Hearing protection in the packaging hall — bottling and canning lines are loud enough to cause permanent damage.

⚠⚠ Brewing commercially is federally licensed — know this before planning a business

• Commercial brewing requires a federal Brewer's Notice from the Alcohol and Tobacco Tax and Trade Bureau (TTB), in addition to state licensing through Florida's DBPR/ABT and to local zoning and occupancy approval. All three, before a drop is sold.
• Federal excise tax applies to beer produced, with reduced rates for small brewers, and it carries recordkeeping and reporting obligations that are a real operational burden.
• Records are a licensing condition, not bookkeeping. Production, transfers, losses, and removals must all be documented, and TTB audits them.
• Labelling and formulation are regulated — TTB label approval, and rules on what claims may be made.
• Florida's three-tier system separates producers, distributors, and retailers, with specific exceptions for brewpubs and taprooms. What a brewery may sell, and to whom, is a legal question with a precise answer that has changed repeatedly in Florida.
• Home brewing is legal within limits and is not a licence to sell. Selling home-brewed beer is a serious offence, and students frequently do not realise this.
• ⚠⚠ This is a fast-moving area. Florida's beverage law has seen repeated legislative change on taproom sales, growlers, and distribution. Rule 11 applies emphatically — verify with TTB, DBPR/ABT, and an attorney before making any business decision.

⚠ The description mentions a laboratory but the course number does not

• Daytona State describes laboratory or production activity in this course, yet publishes it as an unsuffixed three-credit course rather than a C-suffixed combined course.
• Under SCNS Rule 22 the suffix is part of the course number, so the absence of a C is not cosmetic — it means the practical work is delivered inside the standard credit and contact hours rather than as an additional laboratory component.
• This matters for transfer. If a receiving institution carries the same subject as a C-suffixed course, that is a different SCNS number and equivalency does not automatically cross the suffix.
• It also matters for expectations. Practical sessions are part of the scheduled hours here, so the balance of classroom to hands-on time is set by the instructor rather than by a separately timetabled lab.
• Ask the receiving institution in writing before assuming this course satisfies a suffixed requirement elsewhere.

⚠⚠ Food and beverage safety — the failures that close establishments

• Foodborne illness outbreaks close businesses and end careers, and in beverage operations the hazards are less obvious than in a kitchen, which is precisely why they are missed.
• Florida food service establishments are regulated by DBPR's Division of Hotels and Restaurants, with certified food manager and trained food handler requirements. ⚠ Verify current certification requirements — they are set by rule and they change.
• Ice is a food. Ice machines are among the most frequently cited and most commonly neglected pieces of equipment in a bar, and scooping ice with a glass is both a contamination and a broken-glass hazard.
• Soda and beer lines require scheduled cleaning, and neglected draught lines are a genuine microbiological problem as well as a quality one.
• Garnishes are ready-to-eat food handled with bare hands more often than anything else behind a bar — the same rules apply as in a kitchen.
• Keep chemicals away from product, always, and never store a cleaning solution in an unlabelled container. Chemical contamination of a beverage is a serious and entirely preventable event.
• Know the safety data sheets for every chemical you use, and the required personal protective equipment.
• Wash hands properly and frequently, and stay home when ill — reporting illness is a requirement, not a courtesy.
• Glass, wet floors, and knives cause most bar injuries. Never handle broken glass by hand, and never put glassware in an ice well.

How Florida course levels affect transfer

The first digit of an SCNS number denotes the year of offering, not transferability. Courses at the 1000 and 2000 levels transfer transparently between Florida public institutions, and 3000 to 4000 is unproblematic since both are upper division. The boundary that actually matters is 2000 to 3000, where lower-division credit generally cannot satisfy an upper-division requirement. That boundary is live in this prefix: Daytona State offers both an associate-level hospitality programme and an upper-division bachelor's sequence (HFT3373, HFT3700, HFT4064, HFT4253, HFT4277, HFT4809), and a 2000-level course does not substitute for its 4000-level counterpart even where the subject looks identical.

HFT2804 is 3 credits and approximately 45 contact hours, offered fall at Daytona State, and students manage yeast used to brew commercial quantities of beer.

It sits between HFT1287 (Introduction to Craft Beer Production) and HFT2822 (Brewery Operations) — see those guides. ⚠ Confirm with the programme what students under 21 may do in sensory components.
