This desk-research guide compares the systems most widely sold in the UK for 2026, drawing on manufacturer specifications and the sort of owner feedback you will find on retailers such as The Malt Miller, Balliihoo and Amazon UK. Every price below is a rough guide at the time of writing, so always check the current price before you buy.

Quick Picks

What is an all-in-one electric brewing system?

An all-in-one electric brewing system is a single stainless-steel vessel that mashes, sparges and boils your wort using a built-in heating element and an integrated recirculation pump. You drop a perforated grain basket (often called a malt pipe) full of crushed malt into the vessel, and the pump continuously draws wort from the bottom and returns it over the top of the grain bed. That recirculation keeps the mash at an even temperature and builds a natural grain-bed filter, so the wort you collect is clear. When the mash is finished you lift the basket, let it drain, switch the same element up to a rolling boil, add your hops, then chill and transfer to the fermenter.

This is a genuinely different animal from a starter kit and from a traditional three-vessel all-grain setup. A starter kit is usually a tin of hopped malt extract, some brewing sugar and a plastic fermenting bin: you add hot water, stir, pitch yeast and wait, with no mashing involved at all. A traditional all-grain brewery, at the other extreme, uses three separate vessels: a hot liquor tank for heating water, a mash tun for converting the grain, and a boil kettle, usually with gas burners and a fair amount of lifting and heavy pouring between them. An all-in-one collapses all of that into one electric unit that plugs into a domestic socket, which is why it has become the default first all-grain purchase for so many UK home brewers moving on from kits.

The trade-off is that a single vessel handles one batch at a time and is generally sized for a standard 19-23 litre (roughly five-gallon) batch, though larger models push well beyond that. What you gain is full control over grain bill, mash temperature, hop schedule and, ultimately, the character of your beer, without the space, plumbing and burner faff of a multi-vessel rig.

The best all-in-one brewing systems in detail

Grainfather G30 (v3) — the reliable all-rounder

The Grainfather G30 is the system most UK brewers picture when they think “all-in-one”, and for good reason. According to the manufacturer’s specifications it is a 30-litre 304-grade stainless-steel vessel that makes up to around 23 litres of finished beer per brew, with a controlled heating element that adjusts power across the different stages of the brew day and a recirculation pump built in. The current v3 revision uses a redesigned malt basket with a rolled base plate and side perforations, which does away with the central overflow pipe that older models relied on.

Control is handled through the Connect Control Box, which pairs over Bluetooth with the Grainfather Community App so you can drive the mash and boil schedule from your phone and pull recipes into the unit. Owner reviews on The Malt Miller and Amazon UK commonly praise how approachable the app makes a first all-grain brew, and how easy the vessel is to clean thanks to its simple internals. An optional counterflow chiller is available separately if you want faster cooling and cleaner transfers.

Expect to pay around £549 at the time of writing (check the current price), which places it above the value picks but below the flagship G40. It suits the brewer who wants standard 23-litre batches, values a large UK support and spares network, and is happy to pay a little more for a mature, well-documented ecosystem. It runs from an ordinary domestic 13A socket, so there is nothing special to arrange in the kitchen or garage.

BrewZilla Gen 4.1 35L — the value benchmark

The BrewZilla (still known to many as the RoboBrew) is the system that repeatedly gets recommended when budget is front of mind. The Gen 4.1 35-litre model is a single-vessel all-grain unit with a 35-litre capacity, built to make batches up to around 30 litres, according to the manufacturer’s specifications. Its element outputs up to roughly 2400W on a 230-240V supply, so like the Grainfather it runs from a single standard socket rather than needing anything unusual.

Recirculation comes from a magnetic-drive pump bolted into the base, which handles both mash recirculation and pumping wort through a chiller. A false-bottom protection screen is designed to keep the great majority of hop debris and hot break out of the pump, which owner reviews on UK retailers such as BrewKegTap and Get Er Brewed frequently mention as a practical touch that saves cleaning time. The Gen 4.1 also adds a sight glass for reading volumes and offers WiFi and Bluetooth control through the RAPT ecosystem.

Pricing starts at around £360 at the time of writing for the base unit (check the current price), with accessory bundles that add a neoprene jacket, whirlpool arm and heat-exchanger dish costing more. It suits the brewer who wants most of the capability of a premium rig without the premium price, and who does not mind a slightly less polished app experience than the Grainfather. For many people upgrading from kits, this is the sweet spot on price versus features.

Grainfather G40 — for double batches and keg fillers

If 23 litres is not enough, the Grainfather G40 roughly doubles the output. The manufacturer’s specifications describe a system that brews up to around 40 litres per batch, enough to fill two 19-litre corny kegs, with a maximum grain bill listed at around 13kg. The UK model is quoted at 2900W and 230V and ships with a standard three-pin 13A plug, which means it still runs from a normal socket despite the larger element.

The G40 folds in features that are optional or absent on the smaller unit: an integrated counterflow chiller, the recirculation pump, digital control via the Grainfather App, a wider malt basket with a rolled-edge mash plate and no silicone seals, and a built-in sight glass. The wider basket gives a larger draining surface, which the manufacturer positions as reducing the chance of a stuck sparge on big grain bills.

At around £1,095 at the time of writing (check the current price), it is the most expensive mainstream pick here, and that is the point: it is aimed at brewers who have outgrown five-gallon batches, who keg rather than bottle, and who want to brew less often for the same volume of beer. If you are still finding your feet, it is probably more system than you need; if you already know you want 40-litre batches, it saves you buying twice.

Klarstein Brauheld Pro — capacity for the money

The Klarstein Brauheld Pro comes at the category from the value-and-capacity angle. According to the manufacturer’s specifications it is offered in several sizes, including 30L, 35L, 45L and 70L, all built in grade 304 stainless steel, with a circulation pump and a programmable brew cycle. The larger models carry a 3300W element, while the 30L and 35L versions are quoted around 2500W. Klarstein’s MemoryBrew feature lets you store multi-step programmes, with the Pro supporting up to eleven programmable steps and a handful of recipe memory slots.

The circulation system pumps mash from the bottom of the vessel to the top to keep temperatures even, in the same broad fashion as its rivals. Owner reviews on Amazon UK commonly note that the Brauheld undercuts the better-known brands on price for a given capacity, while a smaller number flag that the wider retail-brand support network is not as deep as the Grainfather’s. Prices sit around £420 to £520 depending on capacity at the time of writing (check the current price).

It suits the brewer who wants the most litres per pound and is comfortable with a slightly more generic ecosystem. One practical caution: the 3300W models on the larger vessels draw close to the ceiling of a standard UK 13A socket, so it is worth confirming your supply and not sharing the circuit with other high-draw appliances.

Anvil Foundry 10.5 — the insulated American option

The Anvil Foundry (made by Blichmann Engineering) is a well-regarded all-in-one that is more commonly seen in the US but does surface in the UK through importers and marketplace listings. The 10.5-gallon model is designed for roughly five to six-and-a-half gallon batches, or around 19 to 25 litres into the fermenter, according to the manufacturer’s specifications. Its stand-out design features are a triple low-watt-density element arrangement, quoted at 2800W on a 240V supply, and double-wall insulation that the manufacturer says holds mash temperature very steady. The with-pump version adds a clog-resistant recirculation pump, and the malt basket is rated to around 7kg of grain.

The catch for UK buyers is availability: it is not stocked as consistently as the Grainfather or BrewZilla, so stock and pricing come and go through importers and eBay listings. For that reason it is worth treating the price as something to confirm case by case rather than a fixed figure, and checking that any listing includes the pump and a UK-appropriate plug or supply. It suits the brewer who specifically wants the insulation and multi-element approach and does not mind hunting a little for stock.

A note on the premium end: Ss Brewtech SVBS

For completeness, the Ss Brewtech SVBS (Single Vessel Brewing System) sits at the premium end. The manufacturer’s specifications describe a 45-litre vessel built for five-gallon batches, with a centre-mounted recirculation path and a high-output “Halo” element rated around 4600W. That element is designed around a 240V, higher-amperage circuit rather than a standard 13A domestic socket, and UK pricing and availability are limited compared with the mainstream picks. It is worth knowing about if you want engineering-led build quality and can sort out a suitable supply, but it is not the obvious first upgrade from kits for most people.

Frequently Asked Questions

How is an all-in-one different from the starter kit I used before?

A starter kit is almost always extract-based: you dissolve a tin of hopped malt extract and some brewing sugar in water, top up, pitch yeast and ferment, with no mashing at all. An all-in-one electric system is a full all-grain setup in one vessel. You mash crushed malt at a controlled temperature, recirculate the wort with the built-in pump, then boil and hop in the same vessel. The result is that you control the grain bill, mash temperature and hop schedule, which is where the real flavour differences come from. It is more involved and takes longer, typically a four-to-six-hour brew day, but it is the step that turns a kit follower into a brewer designing their own beer.

What batch size should I choose?

Most brewers upgrading from kits are best served by a 30-35 litre class vessel, such as the Grainfather G30, BrewZilla 35L or a 30-35L Klarstein Brauheld. These make a standard batch of roughly 19-23 litres into the fermenter, which fills a corny keg or a couple of cases of bottles and matches the volumes most recipes are written for. Only step up to a 40-litre-plus system like the Grainfather G40 or a larger Brauheld if you know you want to fill two kegs at once, or brew less often for the same total volume. Bigger vessels also mean more weight to lift when the basket is full of wet grain, so factor in your space and your back.

Do I need a separate boiler or hot liquor tank as well?

No, and that is the whole appeal of the format. The single vessel heats your strike water, holds the mash, and then boils the wort, so you do not need a separate boiler or hot liquor tank the way a three-vessel all-grain brewery does. Many owners do keep a cheap electric urn or a large pan on the side purely to heat sparge water, which speeds the day up a little, but it is optional rather than essential: you can sparge with water heated in the same unit between steps, or brew “full volume” with less sparging at all. The pump and recirculation replace the manual moving of liquid between vessels entirely.

What power supply and socket do I need?

Most single-element all-in-one systems sold for the UK, including the Grainfather G30 and G40 and the BrewZilla 35L, are designed to run from an ordinary 13-amp domestic socket, and the G40 is explicitly supplied with a standard three-pin plug. A 13A socket at UK mains voltage can deliver up to roughly 3kW, so units in the 2400-2900W range are comfortable. Where you need to pay attention is the higher-powered options: the 3300W Klarstein models sit near that ceiling, and imported US-market systems such as the Ss Brewtech SVBS are built around higher-amperage 240V circuits rather than a normal socket. Whichever you choose, give it a dedicated socket, avoid sharing the circuit with other heavy appliances, and never run it from a lightweight extension lead.
