When I started brewing I assumed I needed a full brew stand, a chest freezer, and enough stainless steel to open a commercial kitchen. I was wrong. Small batch brewing — anything from one gallon up to about three — needs surprisingly little gear, and most of it is cheap enough that you can try the hobby without committing your tax refund.

This isn't a shopping list for the person who wants to win a homebrew competition next month. It's the list I wish I had when I was standing in my kitchen wondering if a plastic bucket would explode.

The Bare Minimum

You can make a drinkable one-gallon batch with just a few things. None of them are exotic.

A Fermenter

For one-gallon batches a glass gallon jug works, but I recommend starting with a 1.5–2 gallon fermentation vessel instead. The extra headspace catches the foam from active fermentation and makes temperature swings less dramatic. It also means you are not mopping krausen off your floor because you cut the headspace too close.

I highly recommend the Little Big Mouth Bubbler from Northern Brewer. It holds 1.4 gallons, has a wide mouth that actually fits a hand and a sponge, and is easy to clean without specialized brushes. At the time of writing it sells for $22.99. Get the plain version without the spigot — you do not need the spout for transferring liquid. I bought one with the spout, and over time I have regretted it; the spigot adds a place for leaks and gunk to hide, and a simple siphon is more reliable anyway.

An Airlock and Stopper

The airlock lets CO₂ escape while keeping oxygen and wild yeast out. Pick up a few three-piece airlocks — they're cheap, easy to clean, and you will own more than one eventually. I use the Fastrack S-shaped airlocks (set of 3, $6.85 at the time of writing). They are BPA-free, transparent, and do the job without any fuss.

Pay attention to the rubber bung size your fermenter needs. The Little Big Mouth Bubbler takes a drilled size 5 bung, so make sure whatever stopper you order matches that spec. A size too small will leak; a size too large will fight you every time you sanitize and insert it. Different fermenters require different bung sizes, so whenever you buy a new fermenter, pick up several extra bungs in the matching size at the same time.

Buy several bungs at once. They are cheap and easy to misplace, and you will not want to delay a brew day because one rolled under the fridge. The North Mountain Supply #5.5 drilled rubber stoppers work well and come in a pack of three for about $2.49 at the time of writing.

A Hydrometer

A hydrometer tells you how much sugar is in your liquid before and after fermentation, which lets you calculate ABV. It is not optional if you care about knowing how strong your brew is. They're fragile and only cost about ten dollars, so buy two while you are ordering.

Get one that comes with a test jar. The jar gives you a clean, narrow cylinder to float the hydrometer in, which is much easier than trying to read it inside a fermenter full of foam and hops. I like the Brewer's Elite Hydrometer Combo — it includes the hydrometer, a test jar, and a hard case for about $21.99 at the time of writing.

You also need a way to fill that test jar without making a mess. The best method I have found is a simple turkey baster — draw a sample from the fermenter, squirt it into the test jar, and sanitize it just like everything else. You can pick one up cheap from almost anywhere — the OLESBUR Premium Turkey Baster is about $6.99 at the time of writing if you want a specific option.

A Racking Cane and Siphon Tubing

You need to move liquid from the fermenter to bottles without dumping the yeast cake in. A simple auto-siphon is easier than trying to start a siphon with your mouth, and it gives you much more control over what you transfer.

The Fermtech Mini Auto-Siphon is about $15.99 at the time of writing and is a game changer when moving brew from primary to secondary or secondary to conditioning. This one is sized for small batches. If you ever scale up to larger volumes you will want a larger siphon.

A Bottling Bucket or Bottling Wand

For your first batch you can bottle directly from the siphon tube. It is messy but it works. A bottling wand with a spring tip makes filling bottles far less frustrating and gives you consistent headspace. Most people buy one after their first bottling day.

Bottles and Caps

Save non-twist-off beer bottles and buy a capper. A wing-style capper is fine for a first batch, but a handheld bench-top capper is faster and more consistent once you are doing multiple bottles in a row. You will also need normal crown caps — they are cheap, so buy more than you think you need; you will lose a few to the floor.

I use the FastRack Handheld Bench-Top Capper. At about $18.99 at the time of writing it is a small upgrade that makes bottling day far less tedious. Do not use twist-off bottles — the caps will not seal well and you will end up with flat brew.

That is the setup I started with. I quickly moved to swing-top bottles because they save time and effort on bottling day, and they have worked well for my needs. The eispap swing-top bottles are about $23.99 at the time of writing. I am not bottle carbonating these days; when I do bottle carbonate, I still use crown caps and normal bottles because the pressure needs a stronger seal.

For a one-gallon batch you will fill about four of those swing-top bottles. If you are anything like me and want plenty of bottles in backup, you will want to buy a lot of them, and that is where a lot of the expense hides. I personally have eight large bottles and six small bottles on hand and still feel like I need about six times more than that.

You can also bottle wine and mead into traditional wine bottles with a corking machine. A decent corker runs around $100 on its own, so before you take that jump make sure you enjoy the hobby and will make enough wine or mead to justify the investment. I do not have that setup yet — I still want one someday, but with swing-top bottles working fine it is not high on my priority list.

Cleaning and Sanitization

Brewing is roughly eighty percent cleaning. If that sounds like an exaggeration, wait until your first bottling day. You need a good cleaner for kettles, fermenters, tubing, and bottles, and then a sanitizer for everything that touches the brew after the boil.

When I started I used Five Star PBW. It is an excellent cleaner — it lifts dried krausen, hop residue, and bottle gunk with far less scrubbing than dish soap. At about $29.44 for a 4 lb container at the time of writing, it is worth the money, but the cost adds up when you are cleaning gear every week. For the last few years I have been using unscented OxiClean instead. It works almost as well for a fraction of the price, as long as you rinse it thoroughly and avoid any scented version.

Once everything is clean, it needs to be sanitized. Star San is the standard for a reason — no rinse, effective, and a small bottle lasts a long time. Mix it with distilled water and keep it in a spray bottle for quick work.

I use Star San. The 32 oz bottle is about $28.98 at the time of writing and lasts me years. You can buy smaller bottles, but the large bottle is so much cheaper per ounce that I buy it once and only reorder every two or three years.

A Brewing Kettle

A pot is only required when you are brewing beer. Wine, mead, and other fermentations made from juice or honey do not need a boil step, so you can skip the kettle entirely for those.

For one-gallon all-grain or extract batches you can use a pot you already own, as long as it holds two or three gallons comfortably. For partial boils or stovetop extract brewing a four-gallon kettle is plenty. Stainless steel is nice; aluminum works fine too.

Any kettle will work for small batches up to a few gallons. If you are thinking about making a five-gallon batch of beer, though, you should be looking at a brewing system rather than a stock pot. I personally use the Clawhammer Supply 10 gallon 120V electric brewing system and have loved every moment of brewing with it. This article is about small batches, so I will not go too in depth on it here.

Secondary Fermentation and Conditioning Vessels

For any brew that needs time to clear or age, you will want separate vessels for secondary fermentation and conditioning. I use one-gallon glass North Mountain Supply fermenting jars for both. They are about $14.99 each at the time of writing.

Each of these jars needs its own airlock and drilled bung so gas can escape while the brew ages. I highly suggest looping a rubber band over the airlock and then around the handle on the neck of the jar to keep the airlock from working itself loose, especially when a jar sits untouched for months.

If you plan to keep more than one batch going at once, you will need a lot of these. I currently have four on my shelf and plan to buy about eight more. Brews can sit in conditioning for several months, and some stay there for a year or more. Having enough jars lets you keep several brews conditioning while still having free vessels for secondary fermentations.

The Nice-to-Haves That Are Actually Worth It

Once you know you like brewing, a few purchases make life easier.

A Wort Chiller

For small batches you can chill your pot in an ice bath in the sink. It works. A small immersion chiller saves time, reduces the risk of infection, and makes summer brewing much less annoying. A twenty-five-foot copper or stainless chiller is overkill for one gallon but will handle anything up to three gallons easily.

A Scale

Measuring ingredients by weight is more accurate than volume, especially for hops, priming sugar, and additives. A cheap kitchen scale that reads in grams and ounces is enough.

A Thermometer

Fermentation temperature matters, especially for brew. A stick-on thermometer on your fermenter gives you a quick reading, and an inexpensive digital probe is useful for mash and steeping temperatures.

A Stirring Paddle and Funnel

A long spoon or paddle that reaches the bottom of your kettle is useful. A funnel with a strainer helps transfer wort into a glass jug without spilling or clogging the neck.

What You Can Skip Entirely

• A kegging setup. Bottling is tedious but free if you save bottles. Kegging is great, but it gets expensive fast. A five-gallon Cornelius keg runs about $100–$130 each, and on top of that you need a CO₂ tank, a regulator, tubing, taps, connectors for the kegs, a temperature controller if you convert a freezer into a keezer, and the freezer itself. Depending on whether you buy used or new, it can quickly add up to $1,000–$2,000. It is not required to make good brew.

• A dedicated fermentation fridge. Temperature control matters for clean brew, but you can manage early batches by brewing styles that match your ambient temperature, or by using a swamp cooler setup with a tub of water and frozen bottles. I do not have this setup. I would love to turn a refrigerator into a temperature-controlled fermentation chamber, but I do not have the room in my apartment. I simply ferment primary on my kitchen counter at room temperature, which does fluctuate. Conditioning jars sit on the same counter, out of direct sunlight but still in ambient light. At some point I really do need to set up a fermentation station, but to do that I would need to get rid of my keezer, find a refrigerator to convert into a kegerator, and build some sort of temperature-controlled enclosure. I do not have the time or money for that right now, so it will stay a future project.

• A grain mill. If you buy pre-crushed grain or stick to extract, you do not need one.

• Fancy pH meters and lab gear. Useful later, completely unnecessary for your first few batches.

My Real Advice

Start with a one-gallon extract kit. Brew it, bottle it, drink it, and decide if you enjoyed the process. If you did, buy one or two tools that annoyed you the most. Brewing gear expands to fill your available space and budget faster than almost any hobby, so let your actual batches tell you what you need instead of buying everything upfront.

As you get deeper into brewing you will watch content creators showcase shiny gear — stainless steel fermenters, electric brewing systems, automated pumps, and lab-grade gadgets. That equipment is nice. It can make certain steps faster or cleaner. But you do not need it to make good brew. I almost fell into that trap myself: I would see a product and think, wow, that will help me make better beer. Spoiler alert — it did not. You will create the same brew in a plastic bucket that someone else makes in a polished stainless steel conical. Better gear will not make you a better brewer. Time, practice, and experience will.

The one exception I will emphasize is a brewing system. If you want to move into larger batches of beer, investing in a real brewing system is worth considering. For small batches a kettle is plenty, but once you are brewing five gallons regularly a dedicated system makes the process far more manageable.

What This Actually Costs

If you bought every bare-minimum item we just covered from the links above, you would spend roughly this much:

• Fermenter (Little Big Mouth Bubbler): ~$22.99
• Airlock and stopper (Fastrack airlocks + North Mountain bungs): ~$9.34
• Hydrometer combo with test jar: ~$21.99
• Turkey baster for samples: ~$6.99
• Mini auto-siphon and tubing: ~$15.99
• Handheld bench-top capper: ~$18.99
• Cleaner (PBW, 4 lb): ~$29.44
• Sanitizer (Star San, 32 oz): ~$28.98

That covers the core brewing and bottling setup and comes to roughly $155. It does not include a kettle if you already own a large pot, and it assumes you save non-twist-off beer bottles for free and buy only caps.

From there your path splits:

Option 1 — bottles and caps (cheapest): reuse saved beer bottles and buy crown caps. The capper is already included above, so you are looking at maybe another $5–$10 for a bag of caps. Total stays around $160–$165.

Option 2 — swing-top bottles: the eispap swing-top bottles are about $23.99 per set and a one-gallon batch fills roughly four of them. If you want backups on hand, you will want several sets. Two sets adds about $48, pushing the starter total closer to $200–$205.

Secondary and conditioning vessels: if you plan to age or clear your brew in separate jars, add the North Mountain Supply one-gallon glass jars at ~$14.99 each. One or two is enough to start, but if you keep multiple batches going you will want several. Adding two jars brings the total to roughly $185–$190 with saved bottles, or $230–$235 with two sets of swing-tops.

Prices change, and you can almost always find lower-cost versions of each item by searching the web for deals rather than ordering from the links in this article.

The best tool in your brewery is patience. The second best is a notebook.
