Brewing beer at home is less about expensive gear and more about a few simple pieces of equipment used carefully. For a first batch you need something to ferment in, a way to let gas out without letting air in, a way to move beer without disturbing the sediment, a hydrometer to follow fermentation, sanitiser and bottles.
Most beginners start with a kit: either a beer kit based on malt extract, which skips the most time consuming steps, or an all-grain kit, which is closer to how commercial breweries work. The equipment overlaps a lot, so you can start simple and add pieces later.
This guide walks through each item, the difference between kit types, and the habits that make the biggest difference to the result.
The basic equipment
| Item | What it does | Good to know |
|---|---|---|
| Fermenter | Holds the beer while yeast turns sugar into alcohol and carbon dioxide | Food grade plastic bucket or glass or stainless vessel with a lid |
| Airlock and bung | Lets carbon dioxide escape and keeps air and insects out | Fill with sanitiser solution or water |
| Siphon or tap | Moves beer from fermenter to bottles | Leaves the yeast sediment behind |
| Hydrometer and trial jar | Measures how much sugar is in the liquid | Used to follow fermentation and estimate strength |
| Thermometer | Checks temperature of the liquid | Stick on strip thermometers are cheap and handy |
| Sanitiser | Kills microbes on everything that touches the beer | No rinse sanitisers save time |
| Bottles, caps and capper | Store and condition the finished beer | Swing top bottles skip the capper |
| Long spoon or paddle | Stirs the wort | Plastic or stainless steel, easy to sanitise |

Extract kits or all-grain
Extract kits
An extract kit gives you concentrated malt syrup or dried malt, often already hopped, plus a packet of yeast. You dissolve the extract in water, top up the fermenter, check the temperature and add the yeast. It is the quickest way to brew and needs the least equipment, which makes it a sensible first step.
All-grain brewing
All-grain brewing starts from malted grain. You soak the crushed grain in hot water to release the sugars (the mash), separate the sweet liquid (the wort), boil it with hops, cool it and then ferment. It takes several hours and needs more kit: a large pot or an electric all-in-one brewing system, a grain bag or mash tun, and a way to cool the wort quickly. A fine mesh brewing bag in a large pot, often called brew in a bag, is a popular low cost way to start.
Sanitising: the step that matters most
Most failed home brews are down to infection, not recipes. Wild yeast and bacteria can turn beer sour or give it off flavours. Anything that touches the wort after the boil, or the beer at any stage, should be cleaned and then sanitised:
- Clean first. Remove visible residue with warm water and an unscented cleaner. Sanitiser does not work well on dirty surfaces.
- Sanitise second. Use a brewing sanitiser and follow the dilution and contact time on the label.
- Avoid scratches. Scratched plastic can hide bacteria, so use soft cloths rather than scourers.
- Keep it simple. The fewer pieces you use, the fewer you need to sanitise.
Temperature and fermentation
Yeast is sensitive to temperature. Ale yeasts typically work best at around 18 to 22 °C, while lager yeasts prefer colder temperatures, often around 10 to 13 °C. Always follow the range printed on the yeast packet or kit instructions. Fermenting too warm can produce harsh or fruity flavours; too cold, and the yeast may stall.
Find a spot in your home with a steady temperature, away from radiators and direct sunlight. A stick on thermometer on the fermenter shows the temperature at a glance.
Using a hydrometer
A hydrometer measures the density of the liquid, called gravity. Take a reading before you add the yeast (original gravity, OG) and another when fermentation has finished (final gravity, FG). When two readings a few days apart are the same, fermentation is complete and it is safe to bottle.
The common home brewing formula for estimating strength is:
ABV = (OG minus FG) multiplied by 131.25
For example, an OG of 1.050 and an FG of 1.010 gives about 5.25 % ABV. Knowing the strength of what you have brewed matters, so take readings rather than guessing.
Bottling and conditioning
Siphon the beer off the sediment into sanitised bottles, leaving the yeast layer behind. Many brewers add a small, measured amount of priming sugar so the remaining yeast produces natural carbonation in the bottle. Use only the amount the recipe gives: too much sugar can over pressurise bottles. Store the bottles at room temperature for the time the instructions suggest, then move them somewhere cool.
Once your beer is ready, you will need a good bottle opener, and beer boxes and bottle carriers make it easier to store or share. The guide to choosing beer glasses and tankards covers serving.
Quick checklist
- Start with an extract kit if this is your first brew.
- Get a fermenter, airlock, siphon, hydrometer, thermometer and sanitiser.
- Clean, then sanitise everything that touches the beer.
- Keep fermentation within the yeast’s temperature range.
- Take OG and FG readings, and bottle only when fermentation has finished.
- Use exactly the priming sugar the recipe gives.
- Label bottles with the date and estimated strength.
Common questions
How long does it take to brew beer at home?
Brew day itself takes from under an hour for an extract kit to several hours for all-grain. Fermentation usually takes one to two weeks, and bottle conditioning a few weeks more, so plan on roughly a month from brew day to a finished beer.
Do I need a hydrometer?
It is strongly recommended. It tells you when fermentation has finished, which helps prevent over pressurised bottles, and lets you estimate the strength of the beer.
Why does my home brew taste sour?
The most common cause is infection from equipment that was not properly sanitised. Clean and sanitise everything, keep the fermenter closed with a working airlock and check that fermentation stays within the right temperature range.
