The home brewing equipment market is enormous, and most of it is aimed at people who do not yet know what they need. The result is starter kits with too-small kettles, extract-only setups that limit what you can brew, and expensive all-in-one systems that beginners do not know how to use. This guide takes a different approach: it starts with the minimum viable setup and explains when (and why) to expand.
A practical small-batch setup using 5-gallon (19-litre) containers. Simple, inexpensive, and sufficient for most beginner recipes.
The Essential Kit: Four Items
To brew all-grain beer at home, you need four core pieces of equipment. Everything else is either convenience or marginal improvement.
1. Brew Kettle
For a 20-litre finished batch, you need a kettle of at least 30 litres capacity — you will have 25–26 litres of wort pre-boil, which can foam and needs headspace. Stainless steel is the standard material: it is durable, easy to clean, non-reactive, and lasts decades. Look for a kettle with a ball valve at the bottom for easy draining, and a thermometer port.
Volume markings inside the kettle are useful but not essential — a long sanitised wooden dowel or a steel ruler can serve as a dipstick. Avoid aluminium kettles: they work, but they are harder to sanitise thoroughly and can impart off-flavours if pitted.
A good 30-litre stainless kettle with a ball valve costs approximately 60–100 EUR from homebrew suppliers or general catering equipment stores. It is worth buying quality here — this item will outlast everything else in your setup.
2. Mash Tun
For all-grain brewing, you need a vessel to hold the grain and hot water during mashing. The simplest and most effective option for a beginner is a cooler (cool box) converted with a stainless steel braid or false bottom. The insulation of a cooler maintains temperature during the 60-minute mash without any external heat source.
A 40-litre cooler works for batches up to 25 litres with typical grain bills. Some brewers use their kettle as the mash vessel on a heat source — this is the "single vessel" approach favoured by electric all-in-one systems (Robobrew, Grainfather) and requires careful temperature monitoring.
3. Fermentation Vessel
The fermenter holds your wort while yeast does its work. The two most common options are plastic buckets and glass/PET carboys.
- Food-grade plastic bucket (30L): Cheap, lightweight, easy to clean. The main drawback is that plastic scratches, and scratches harbour bacteria. Replace after 2–3 years of regular use. Excellent for beginners.
- Glass carboy: Inert, easy to inspect, does not scratch. Heavy and fragile — dropping a full glass carboy is dangerous. Use a carboy carrier and handle with care.
- PET or HDPE plastic carboy: A compromise between bucket and glass. Lighter than glass, more scratch-resistant than standard buckets. Increasingly popular.
The fermenter needs an airtight lid with a hole for an airlock, or a two-piece airlock and bung. Fill the airlock with a small amount of Star San solution (not water, which can evaporate) to let CO&sub2; escape while keeping oxygen and contaminants out.
4. Wort Chiller
Cooling 20 litres of boiling wort quickly is the most time-critical step in brewing. Slow cooling risks DMS formation and bacterial contamination during the vulnerable period between 45°C and 20°C (the "danger zone" where bacteria multiply fastest but are not killed).
| Chiller Type | Cost | Speed | Notes |
|---|---|---|---|
| Immersion chiller (copper) | 30–60 EUR | 15–20 min | Coiled copper tube, placed in kettle, cold water runs through |
| Immersion chiller (SS) | 50–90 EUR | 15–20 min | More durable, easier to sanitise, same principle |
| Plate chiller | 70–150 EUR | 5–10 min | Faster, but harder to clean and prone to blockage |
| Ice bath | 0 | 30–45 min | Slow, wasteful of ice, but works for very small batches |
Active fermentation — CO2 bubbles rising through a glass fermenter. Healthy fermentation typically shows vigorous activity within 12–18 hours of pitching.
Measurement Tools
Brewing without measurement is guesswork. These two tools are non-negotiable:
- Hydrometer or refractometer: Measures the density of your wort to determine sugar content (and later, alcohol). A hydrometer is the traditional tool — cheap, accurate, and requires no calibration. A refractometer is faster (uses one drop of liquid) but needs correction calculations after fermentation due to the presence of alcohol. For beginners, start with a hydrometer.
- Thermometer: A digital instant-read thermometer accurate to ±0.5°C is sufficient. Use it for strike water, mash temperature monitoring, and pitching temperature. Analogue thermometers work but are typically slower and less precise.
Sanitation
No equipment investment compensates for poor sanitation. Every surface that contacts your wort after the boil must be sanitised. Star San (phosphoric acid-based, no-rinse) and IO Star (iodine-based) are the most widely used sanitisers among homebrewers. Mix as directed, contact for 1 minute, and let drain — do not rinse.
A spray bottle filled with Star San solution is the most practical sanitation tool in the brewery. Spray, let drain, brew. The foam it produces is harmless and does not affect beer flavour despite what anxious beginners sometimes think.
Temperature Control for Lagers
If you want to brew Czech-style lagers — and given the tradition in this region, you probably do — temperature control is not optional. Lager yeast ferments at 8–12°C and conditions at 1–4°C. Without a controlled environment, you cannot make a clean lager.
The standard homebrew solution is a dedicated fridge with an external temperature controller (such as the Inkbird ITC-308 or STC-1000). The controller cuts power to the fridge when the target temperature is reached, maintaining the fermenter at a precise temperature. A second-hand bar fridge large enough to hold a 30-litre fermenter costs 20–60 EUR. The temperature controller adds another 15–30 EUR. This is the most impactful equipment upgrade for Czech-style brewing.
What to Buy First: A Practical Order
- 30-litre stainless kettle with ball valve
- 40-litre cooler converted to mash tun (or buy a pre-made kit)
- 30-litre food-grade plastic bucket fermenter + airlock
- Copper immersion chiller
- Hydrometer + test tube
- Digital thermometer
- Star San sanitiser (1L concentrate)
- Auto-siphon and flexible tubing for transfers
With this list, you can brew 20-litre all-grain batches of ales from the first weekend. Total cost: 150–250 EUR depending on source and quality. Spend more on the kettle and less on the fermenter — you can replace the bucket, but a good kettle lasts 20+ years.
In the Czech Republic, homebrew equipment and ingredients are available from Pivovarsky Dum and various online homebrew shops. German suppliers like Braubedarf ship to CZ with reasonable delivery costs for larger orders.
All-in-One Electric Systems
Systems like the Grainfather G30, Brewzilla (Robobrew), and Klarstein Mundschenk combine mash tun, kettle, and heating element into one vessel. They simplify the process significantly and remove the need for a separate mash tun. The trade-off is cost (250–700 EUR) and less flexibility for large grain bills or unusual batch sizes.
For someone who is serious about brewing and has the budget, an electric all-in-one is a legitimate first purchase. For someone testing whether they enjoy brewing before committing significant money, the basic kit described above is the better starting point.
