You want clear answers on brew vs fermentation. Yet online guides mix terms and make choices harder. Here’s a simple, expert walk-through that untangles steps, shows equipment, and helps you plan beer, wine, or cider—with options to scale smartly.
Brewing is the process of making wort from grains (mash, lautering, boil with hop, cool) before yeast work begins. Fermentation is the process where yeast converts sugars into alcohol and carbon dioxide, turning wort, grape must, or apple juice into beer, wine, or cider. Distillation is the process of separating alcohol by heating a fermented liquid to raise alcohol content for spirits.

What does “brew” actually mean in a brewery?
To brew means to prepare a sugar-rich liquid (wort) from malted grains—usually barley—so yeast can do its job later. In plain steps, the brewing process starts with crushing malt, mixing with hot water to extract sugars (the mash), then a process called lautering separates sweet liquid (wort) from grain. A vigorous boil with hop follows, adding bitterness, aroma, and stability.
Think of brew as the kitchen part of producing beer: you build flavor and fermentability before yeast ever enters the scene. In other words, brewing is the process used in beer production to make a fermentable, flavorful wort; brewing is used well before fermentation, and beer is made from this wort once yeast arrives.
“Brew” = prepare the food for yeast. “Ferment” = let yeast eat that food.

How does the fermentation process work?
Once wort (or grape must, or apple juice) is oxygenated and pitched, yeast converts sugars into alcohol—specifically ethanol—and carbon dioxide. That sentence is the whole magic. Put simply, fermentation is a process where microorganisms produce alcohol and bubbles from sugar.
Here’s the simple chemistry you can tell your team: sugars → sugars into alcohol and carbon dioxide. Temperature control, sanitation, and tank geometry shape mouthfeel and esters when fermentation is done. In fermenting beer, ales run warmer than lagers: a classic ale likes ~18–22 °C. A well-designed fermentation tank improves heat removal and keeps yeast happy. See a stainless beer fermentation tank that supports precise control and CIP.
Fermentation vs distillation: what’s the difference?
Fermentation creates alcohol; distillation is the process that concentrates it. Beverages produced through fermentation alone include beer and wine (and cider). Distilled spirits—like whiskey, gin, and vodka are distilled—start with a fermented base, then run through a still to raise the concentration and alcohol content.
Quick comparison chart (typical values):
| Beverage type | Steps used | Typical ABV (alcohol by volume) | Distilled? |
|---|---|---|---|
| Beer | Brew → ferment → condition | 4–8% | No |
| Wine | Crush/press → ferment → condition | 9–15% | No |
| Cider | Press → ferment → condition | 4–8% | No |
| Spirits | Ferment → distillation process | 35–45%+ | Yes |
In short: brew builds fermentable liquid; fermentation is the process that makes an alcoholic beverage; distillation raises strength.
Distillation and fermentation: when do both apply?
Many distilled products start life like beer or cider. You might use brewing and distillation to convert a grain mash into spirits: distillation to convert plant sugars first requires yeast to make alcohol from a process that uses plant sugars. After fermentation, the fermented liquid is heated; lighter alcohol vapors rise and condense. That’s how distillation is used to reach higher alcohol content.
In practice, a distillery ferments a grain, fruit, or molasses wash, then runs a distillation process to shape character and proof. Heads and tails cuts control congeners; proofing water can dilute the alcohol and mellow the spirit. Some products are stored in a barrel for months or years.
What steps make up “brew”—from mash to wort?
Brewers grind malt so hot water activates enzymes. Those enzymes break starch into sugar your yeast can eat. You use hot water to extract starch-turned-sugars (the mash), then a process called lautering clarifies sweet wort. The kettle hop boil builds flavor and stability. Then chilling sends clean wort to a sanitized tank.
A typical “process of making beer” flow:
- Mill malt (from barley)
- Mash with water → enzymes release sugar
- Lauter → bright wort
- Boil with hop additions
- Whirlpool / trub removal
- Chill and oxygenate
- Transfer to fermentation vessels
- Pitch brewing yeast
For efficiency, a 3-vessel brewhouse (mash/lauter + kettle/whirlpool + HLT) reduces changeover times and keeps wort quality high. See a production-ready 3-vessel brewhouse.
What role does yeast play in beer, wine, and cider?
Yeast is the working partner in every fermented beverage. In beer, brewing yeast strains (ale vs lager) shape beer styles—from fruity esters to clean finishes. In wine, strains support terroir and fruit; in cider, neutral or aromatic strains protect delicate apple notes. The amount of alcohol depends on fermentable sugar, pitch rate, health, and time.
Simple yeast guide (quick “chart”):
| Product | Typical yeast range | Notes |
|---|---|---|
| Ale beer | 18–22 °C | Fast, ester-driven; great for craft beer |
| Lager beer | 8–12 °C | Clean profile; longer cold conditioning |
| Wine | 12–25 °C | Fruit-friendly; a wine maker adjusts nutrient |
| Cider | 12–20 °C | Preserves apple; sulfite and nutrient help |
If your team also makes kombucha or mixed-culture products, pitch control and vessel finish matter even more. For fruit fermentations, see a sanitary wine fermentation vessel and purpose-built cider brewing equipment.
Is beer brewing different from brewing and winemaking?
Yes. Beer begins with grains; brewing and winemaking use different raw materials and prep. In beer, grains must be mashed to free sugar from starch; in wine, grapes already bring sugars. You make wine by crushing and pressing fruit; a winery ferments juice or must without a “brew” mash step. That’s a key difference between brewing beer and fermenting wine.
Beer is usually bittered with hops and often carbonated; wine leans on acid/tannin and fruit. Both may see oak; both can have secondary fermentation (think bottle-conditioned beer or malolactic in wine). If you produce both beer and wine under one roof, separate tool sets and cleaning SOPs keep flavors clean.
What makes a drink a fermented beverage?
A drink is a fermented beverage if it’s produced through fermentation by microbes that ferment sugars. Beer, wine or mead, and cider fit this perfectly. Their alcohol is produced biologically, not by adding ethanol. Some products finish fermentation but also age or clarify further—fermentation but also cold-crash, fine, or filter to polish flavor.
After primary, liquid can move to a fermentation tank for further processing (diacetyl rest, dry hop, conditioning). Some beer can be stored cold in a bright tank to clarify and carbonate before packaging.
When is a product considered distilled?
A product is distilled when a still separates and concentrates ethanol from a low-proof base. In a simple definition: distillation is the process of boiling and condensing to raise proof. Grain washes, wines, or ciders fermented to produce alcohol are then run through pot or column stills to make distilled spirits. That’s how beer and spirits differ in the finish.
Key idea: fermentation makes alcohol; distillation concentrates it. Spirits sometimes have an alcohol concentration far higher than beer or wine, which is why proofing water and wood can shape final mouthfeel.
How do equipment choices change quality, speed, and cost?
Vessel geometry, jackets, and controls all matter. A conical fermentation tank with racking arms lets you remove yeast and keep beer bright. A dedicated bright tank speeds carbonation and packaging. Post-ferment, you can dilute the alcohol and mellow intensity, or age stored in a barrel for layered notes. The right brewing techniques and tank setup help you hit target alcohol by volume and flavor repeatably.
Consider adding a bright beer tank to streamline finishing. For hot-side gains, compact brewhouses reduce losses at transfer so your brewer can reclaim yields. With clean utilities and heat-exchange, your brewer saves time and gets steadier results.
Mini case study: scaling from nano to 15 bbl
A neighborhood taproom started with a 3 bbl brewing beer rig and outgrew it in 12 months. They moved to a 10 bbl “two turns to 20” layout with conicals, a CIP loop, and a bright tank. Grain-to-glass dropped from 21 to 14 days for the flagship beer styles while keeping the same alcohol by volume range (5.2–6.3%). The new brewhouse cut brewhouse losses by 1.5–2.0%.
They kept a small pilot for home brewing ideas. A seasonal cider slot also launched—fermented in jacketed tanks with gentle transfers. That same platform later fed a small still to craft a botanical gin—an example of distillation and fermentation living side by side in one facility.
If you’re exploring a jump, compare modular systems like beer-brewing equipment and the flexible beer fermentation tank.

FAQs
Is ferment the same as brew?
No. You brew to prepare wort; you ferment to make alcohol. Brewing ends at chilled wort; fermentation starts when yeast is pitched and the chemical process begins.
Can I skip brew for wine or cider?
Yes. Fruit already brings sugar. You make wine or cider by crushing/pressing and fermenting. There’s no mash step.
What gives beer bitterness?
Hop additions in the boil. Timing changes flavor. Early = bittering; late = aroma. Dry hopping happens post-boil, sometimes during secondary fermentation.
Why are spirits stronger than beer or wine?
Because of distillation. Distillation is used after fermentation to raise proof; beer might sit at 5–7% ABV, while spirits reach 40%+.
Do I need special tanks?
Purpose-built fermentation vessels improve control and safety. Jacketed conicals help manage heat and allow clean yeast harvests.
What’s the simple line that defines alcohol production?
“Yeast eats sugar and makes alcohol and carbon dioxide.” That’s the heart of alcohol production across beer, wine, and cider.
