Making beer from a kit is one of the easiest ways to get into home brewing - and you don't need any experience to get started. If you can boil a kettle and follow a few simple steps, you can make genuinely great beer at home for a fraction of the price you'd pay in the shops.
In this guide, we'll walk you through the full step-by-step process of making beer from a kit, from sanitising your equipment to pouring your first pint. Whether you've just picked up your first beer kit or you're still deciding if home brewing is for you, this is everything you need to know to home brew with confidence.
Here's a quick overview of what's involved:
-
Clean and sanitise all your equipment
-
Warm your beer kit and add the contents to your fermenter
-
Add brewing sugar and hot water, then stir well
-
Top up with cold water to the required volume
-
Take your first hydrometer reading
-
Add the yeast and give it a gentle stir
-
Seal the fermenter, fit the airlock, and leave to ferment
-
Once fermentation is complete, bottle or keg your beer
-
Leave to condition for at least two weeks
-
Chill, pour, and enjoy
That's it. Ten straightforward steps between you and your first homebrew. Let's break each one down properly so you know exactly what to do (and what to avoid).
Why Make Beer from a Kit?
If you've never brewed before, it's natural to wonder whether it's worth the effort. The short answer is - absolutely!
Beer kits have come a long way, and they're designed to make the process as straightforward as possible while still producing delicious beer you'll genuinely enjoy drinking. 3% of the UK population brews beer or makes wine at home. Here’s why thousands of people across the UK are switching to home brewing:
It's Easier Than You Think
Making beer from a kit isn't complicated. There's no specialist knowledge needed, no science degree required, and you won't need to convert your garage into a microbrewery.
A beer kit does the heavy lifting for you - the malt extract, hops, and yeast are pre-measured and ready to go. Your job is to follow the steps, keep everything clean, and let time do its thing.
The hands-on part of brew day takes around 30 to 45 minutes. You'll dissolve the kit contents, add water and yeast, then seal up your fermenter and walk away. Fermentation takes care of the rest over the next week or two. If you've ever followed a recipe in the kitchen, you've already got the skills you need.
It's Seriously Cheap
This is the one that surprises most people. Once you've picked up your basic brewing equipment (a fermenter, airlock, syphon, and a few bottles or a keg), you can reuse it all batch after batch. The only ongoing cost is the kit itself, and most beer kits produce around 40 pints.
Do the maths, and you're looking at roughly 30p to 75p a pint, depending on the kit you choose. Compare that to £5 or more for a pint down the pub (or £2+ per can from the supermarket), and it starts to make a lot of sense.
There's no duty to pay on beer brewed at home for personal consumption either, which is one of the reasons the savings are so significant.
It's a Hobby That Grows With You
One of the best things about home brewing is that you can start simple and take it as far as you want. You might start with a simple homebrew starter kit, before moving on to premium kits for richer, more complex flavours. From there, some brewers step up to all-grain brewing, where you're working with malted barley and hops separately and have full control over every element of the recipe. Others get hooked on kegging their beer with corny kegs instead of bottling - it's quicker, easier to serve, and gives you that pub-quality draught pour at home.
However far you take it, most brewers start in the same place: with a beer kit, a fermenter, and a bit of curiosity.
What You Need to Get Started
Before you crack open your first beer kit, it helps to know what you're working with and what equipment you'll need alongside it.
What's Inside a Beer Kit
Every beer kit is slightly different, but most contain the same core ingredients. You'll typically find two cans or pouch of malt extract - this is the concentrated base that gives your beer its body, colour, and flavour. Some kits also include a separate packet of hops, a sachet of yeast, and brewing sugar or enhancer.
Everything is pre-measured, so there's no guesswork. You just follow the instructions included with your kit.
Essential Brewing Equipment
To brew your first batch, you'll need a few basic bits of kit:
-
Fermenter with a lid and airlock - this is where your beer ferments. A standard food-grade bucket with a grommet and airlock does the job perfectly.
-
Syphon - for transferring your beer without disturbing the sediment.
-
Sanitiser - the single most important thing in home brewing. Everything that touches your beer needs to be properly cleaned and sanitised.
-
Hydrometer - a simple tool for checking when fermentation is complete. Not essential for your first brew, but well worth having.
-
Long-handled spoon - for stirring. Avoid wooden spoons as they're difficult to fully sanitise.
-
Bottles with caps or a keg - you'll need something to put your finished beer in.
If you're starting from scratch, a starter equipment kit bundled with a beer kit is the most cost-effective way to get everything in one go.
Optional Extras That Make Life Easier
None of these are essential for your first brew, but they'll make the process smoother and your results more consistent:
-
Temperature strip or thermometer - helps you pitch your yeast at the right temperature and monitor fermentation.
-
Brew enhancer or spraymalt - swap this in for plain sugar to improve the body and flavour of your beer (two can kits don’t need any enhancer).
-
Bottle tree and capper - speeds up bottling day significantly if you're not kegging.
-
A keg and CO2 setup - if you'd rather skip bottling altogether, kegging is quicker, easier, and gives you pub-quality draught beer at home. It's what we specialise in here at BrewKeg Tap.

How to Make Beer from a Kit - Step by Step
This is the part you've been waiting for. Follow these ten steps, and you'll have your first homebrew fermenting in under an hour. Every beer kit is slightly different, so always read the instructions that come with yours - but the process below applies to the vast majority of kits available in the UK.
Step 1 - Clean and Sanitise Everything
This is the most important step in the entire process. If bacteria or wild yeasts get into your beer, it will spoil, and no amount of high-quality ingredients will fix that.
Before you start, clean and sanitise everything that will come into contact with your brew - your fermenter, lid, airlock, spoon, syphon, and any jugs or measuring equipment. Use a dedicated brewing sanitiser rather than regular washing-up liquid. If the equipment needs cleaning, use a brewery cleaner. Once clean, a sanitiser should be used.
Follow the instructions on the sanitiser, rinse if required, and work with your equipment while it's still freshly sanitised.
If you only remember one rule from this entire guide, make it this one: if in doubt, sanitise it.
Step 2 - Warm and Add Your Kit Ingredients
Most beer kits come as a thick, sticky malt extract in a can or pouch. To make it easier to pour, stand the unopened can in warm water for about twenty minutes. This loosens the contents so you can get every last bit out.
Once it's warmed through, open the can and pour the malt extract into your sanitised fermenter. Rinse the inside of the can with a little hot water to get any remaining extract out, and add that to the fermenter as well.
Step 3 - Add Brewing Sugar and Hot Water
Your kit instructions will tell you how much sugar or brew enhancer to add. Pour it into the fermenter along with the amount of hot (not boiling) water specified in your kit's instructions. This is usually around 2 to 4 litres. If using a Fermzilla, please don’t use boiling/very hot water, as they are prone to melting under high temperatures. The mixture in the fermzilla should not exceed 50 °C.
Stir the mixture vigorously for a good few minutes until the malt extract and sugar are fully dissolved. You shouldn't see any lumps or sticky residue at the bottom. Taking the time to dissolve everything properly here makes a real difference to the finished beer.
Step 4 - Top Up With Cold Water and Stir
Now add cold water to bring the total volume to the level marked on your fermenter - usually 23 litres. The cold water also helps lower the temperature, which is important before you add the yeast in the next step.
Give it another good stir to make sure everything is evenly mixed.
Step 5 - Take Your First Hydrometer Reading
If you have a hydrometer, now is the time to take your first reading - this is called the Original Gravity (OG). Pour a small sample into your hydrometer trial jar, lower the hydrometer in gently, and read the number on the scale at the liquid's surface. Most beer kits will have a specific gravity somewhere around 1.036 to 1.045.
Write this number down. You'll compare it with a second reading later to know when fermentation is finished, and it also lets you work out the approximate alcohol content of your beer.
If you don't have a hydrometer yet, don't worry - your beer will still turn out fine. But it's a handy tool to pick up for future brews.
Step 6 - Add the Yeast
Check that the temperature of your liquid is between 18°C and 24°C. This is important — if it's too hot, you'll kill the yeast. If it's too cold, the yeast won't activate properly.
Once you're in the right range, sprinkle the yeast evenly over the surface of the liquid. Some brewers give it a gentle stir, others leave it to sit. Either way works fine. The yeast will get to work on its own.
Step 7 - Seal, Fit the Airlock, and Wait
Pop the lid firmly onto your fermenter and fit the airlock into the hole in the lid. Fill the airlock with water or sanitiser to the line marked on it - this lets CO2 escape during fermentation while keeping air and bacteria out.
Move the fermenter to a location with a steady temperature between 18°C and 24°C. Avoid anywhere with big temperature swings like a garage or conservatory. A cupboard, spare room, or under the stairs works well.
Within 24 to 48 hours, you should see bubbles coming through the airlock. That's your yeast doing its job - turning sugar into alcohol and CO2.
Now all you need is patience. Fermentation typically takes 7 to 14 days, depending on the kit and the temperature.
Step 8 - Check Fermentation Is Complete
Don't rush this step. Your beer might look ready, but the only reliable way to know is by taking hydrometer readings.
Take a reading and note the number. Wait 24 hours and take another. If both readings are the same (and the level has dropped to around 1.008 to 1.014) fermentation is complete, and your beer is ready to bottle or keg.
If the readings are still changing, leave it another day or two and test again. Bottling or kegging too early can result in overcarbonation and in the worst case, exploding bottles. It's always better to wait an extra day or two than to rush.
Step 9 - Bottle or Keg Your Beer
Now it's time to package your beer. You've got two options:
-
Bottling: Sanitise your bottles, caps, and syphon tube. Add two carbonation drops or half a teaspoon of sugar to each 500ml bottle. Syphon the beer carefully from the fermenter into each bottle, leaving the sediment behind. Cap the bottles securely.
-
Kegging: If you've got a keg setup, syphon the beer into your sanitised keg, seal it, and carbonate using CO2. Kegging is faster, easier, and gives you pub-quality draught beer straight from the tap - no priming sugar needed, no waiting for bottle carbonation, and no sediment in your glass. It's the reason we started BrewKegTap in the first place.
Whichever method you choose, try to avoid splashing or disturbing the sediment at the bottom of the fermenter when transferring.
Step 10 - Condition, Chill, and Enjoy
Your beer isn't quite finished yet. It needs time to condition - this is where the flavour develops, and the carbonation builds.
-
If you've bottled: Leave the bottles somewhere warm (around 20°C) for 1-2 weeks to carbonate, then move them to a cool spot. Test for carbonation (drink!) before moving from warm to cool for storage. The longer you leave them, the better they'll taste. Most homebrew hits its stride after 3 to 4 weeks of conditioning.
-
If you've kegged: You can force carbonate and your beer will be ready to drink within a few days, though even kegged beer benefits from a week or two of cold conditioning.
When you're ready, chill your beer, pour it, and enjoy the satisfaction of drinking something you made yourself. That first sip of your own homebrew is a moment every brewer remembers.
Common Mistakes When Making Beer from a Kit (And How to Avoid Them)
Most first brews turn out well, but there are a handful of mistakes that trip up beginners time and again. The good news is they're all easy to avoid once you know what to look out for.
Not Sanitising Properly
This is the number one reason homebrew goes wrong. Bacteria and wild yeasts love the warm, sugary environment inside your fermenter, and even a small amount of contamination can turn a perfectly good batch sour or give it unpleasant off-flavours.
The fix: Clean and sanitise everything that touches your beer - every time. If something falls on the floor, sanitise it again before it goes anywhere near your brew. No rinse sanitisers (like Chemsan) are great as you don't need to rinse the sanitiser - just keep a bucket or washing up bowl with some in and dip anything that comes into contact with the beer into it before putting it near the beer.
Fermenting at the Wrong Temperature
Yeast is fussy about temperature. Too warm and it produces harsh, fruity off-flavours. Too cold, and it slows right down or stalls completely. Most ale yeasts work best between 18°C and 24°C, but big temperature swings are just as damaging as being outside the range.
The fix: Keep your fermenting vessel in a location with a consistent, stable temperature. Avoid garages, sheds, and conservatories where temperatures can fluctuate wildly. An indoor cupboard or spare room is usually ideal. Wrapping an old duvet or some bubble wrap around the fermenter can help keep it warm - be careful not to make it too warm, though!
Rushing the Process
It's tempting to bottle early or crack open a beer before it's properly conditioned. But cutting corners on time is one of the quickest ways to end up with flat, green-tasting beer - or worse, overcarbonated bottles. If this happens, then something has gone wrong - too much sugar added (or too high pressure for kegs).
The fix: Let fermentation finish completely and confirm it with consistent hydrometer readings over two days. Once bottled or kegged, give your beer at least two weeks to condition.
Using Old or Poor-Quality Yeast
Yeast is a living organism, and it doesn't last forever. If your kit has been sitting on a shelf for a long time, the yeast sachet that came with it may have lost its effectiveness. Weak yeast results in sluggish or incomplete fermentation, leading to lower alcohol, more residual sweetness, and a higher risk of off-flavours.
The fix: If you're unsure how old your kit is, swap the included yeast for a fresh sachet of quality brewing yeast. It's a small cost that makes a big difference to the reliability and flavour of your finished beer. All our yeasts are stored at 4°C and are guaranteed to have at least many months remaining until the expiry date.
Adding Too Much Sugar
More sugar doesn't mean more or better beer. Excessive sugar produces a thin, dry, overly boozy brew with a harsh, almost cidery taste - the opposite of what most people are after. This applies to both the brewing stage and priming at bottling.
The fix: Follow your kit instructions on sugar quantities. At bottling, stick to the recommended amount of priming sugar - one carbonation drop (two drops for lager) or half a teaspoon per 500ml bottle is plenty.
What's Next - Growing Your Brewing Hobby
Once you've brewed your first batch and tasted the results, chances are you'll want to do it again. And again. That's how it starts for most home brewers! The beauty of this hobby is that there's always a next step - and each one gives you more control, better beer, and more to experiment with.
Move Up to Extract or All-Grain Kits
When you're ready to take full control, all-grain brewing is where things get really interesting. Instead of using pre-made malt extract kits, you're mashing real malted grain to create your wort from scratch. It takes a bit more time and equipment, but it opens up endless possibilities for creating your own recipes and dialling in exactly the flavours you want. Browse our all-grain beer kits to see what's available.
Invest in a Proper All-Grain Brewing System
If all-grain brewing sounds like your kind of thing, a dedicated all-in-one all-grain brewing system makes the process far more straightforward.
An all-in-one electric system like the Brewzilla handles mashing, boiling, and cooling in a single unit - no juggling multiple pots or rigging up DIY setups. You plug it in, set your temperatures, and it does the heavy lifting. Once you've brewed on a system like this, you won't look back.
Pair it with a pressure-capable fermenter like the Fermzilla, and you've got a setup that gives you complete control over every stage of the process.
Start Kegging Your Homebrew
If there's one upgrade that transforms the home brewing experience, it's kegging. Bottling works well, but it's time-consuming to wash, sanitise, fill, and cap dozens of beer bottles each time you brew. Kegging cuts all of that down to a single transfer.
With a basic keg setup, you syphon your beer into a keg, connect the CO2, and you're done. No priming sugar, no waiting weeks for bottle carbonation, no sediment in your glass. Just clean, clear, pub-quality draught beer from your own tap whenever you fancy one.
Take a look at our keg kits to find the right setup for you, or explore our Premium Single Keg Kit - our most popular starter kegging bundle.
