Anvil Foundry vs BrewZilla: 120V/240V all-in-one compared

Two of the most common electric all-in-ones in US garages, compared on the numbers that decide your brew day: watts, grain, batch size and what comes in the box.

The short version
  • Anvil Foundry 10.5 switches between 120V at 1600 W (13 A) and 240V at 2800 W (12 A), per its listing. It is the pick if you may add a 240V circuit later.
  • KegLand BrewZilla Gen 4 35L (110V) has a built-in pump, automatic step mashing, RAPT Wi-Fi and an immersion chiller on the Wi-Fi model. Its 110V elements total about 1500 W per retailer listings.
  • Both make about 5 gal (19 L) of finished beer per batch. The BrewZilla lists a bigger recommended grain bill (23.5 lb vs 16 lb).
  • Either one needs a GFCI-protected circuit and no extension cord. Any 240V circuit is a job for a licensed electrician.

The Anvil Foundry vs BrewZilla question comes down to one thing first: your outlet. Both are single-vessel electric all-in-ones that mash, boil and (with a pump) recirculate in one stainless pot, and both are sized for the classic 5-gallon (19 L) batch. They differ in how they get heat into the wort, how much automation is built in, and what the box includes.

This page lines up the listed specs of each brand's current models side by side, using the product listings, maker material and retailer spec sheets cited at the bottom. Where a listing doesn't give a figure, the table says "not listed". The brewing systems hub has every all-in-one in the catalogue, and the going all-grain page puts these systems in context with BIAB and three-vessel setups.

Two notes on the table. First, the newer 10.5 and 6.5 Foundry listings describe a 240V system with a 120V adapter cable, while the older pump bundle lists a switch; the wattage figures (1600 W / 2800 W) come from that pump-bundle listing and Northern Brewer's spec page, so check the manual of the exact unit you buy. Second, KegLand's own manual warns that 110V BrewZilla units in the US run at lower wattage than the 220–240V versions shown on its international pages, which is why the 1900 W figure you may see online does not apply to the 110V model.

How much heat do you get on a normal outlet?

Heating power decides how long you wait for strike temperature and how hard the boil rolls. On a standard 120V outlet both brands land in the same range, but the Foundry has a second gear: flip it to 240V and it nearly doubles its power.

Both 120V draws sit close to the limit of a typical 15 A household circuit, so nothing else should share that circuit while you brew. A dedicated 20 A circuit with GFCI protection is the comfortable setup, and the manual for your unit is the final word on what it needs. If you already have (or plan) a 240V circuit, only the Foundry takes advantage of it; for a 240V BrewZilla you buy a different model.

Electric brewing: GFCI and a licensed electricianPlug 120V and 240V systems only into a GFCI-protected circuit of the type the manual calls for, with no extension cords. A 1600 W system on 120V draws about 13.3 A (W ÷ V), close to a 15 A circuit’s limit. Have a licensed electrician install any new circuit, 120V or 240V.Source: Anvil Foundry manual (GFCI protection for 240V hookups); W ÷ V arithmetic

Grain capacity and batch size

Grain capacity sets how strong a 5-gallon beer you can make without topping up with extract or sugar.

In practice 16 lb covers almost every 5-gallon recipe up to strong ales. The Foundry 10.5 is built for 5-gallon batches; Anvil's own Q&A answer is that 10 gallons needs the 18-gallon Foundry. The BrewZilla 35L lists 5–6 gallons of finished beer, and its 65L sibling moves up to 10–12 gallons on 220V. The Foundry 6.5 is the small-batch option for 2.5–3 gallons, handy if you brew often and drink slowly.

Use the strike water calculator (it has an all-in-one toggle, since both systems heat the mash water in the vessel) and the dilution and boil-off calculator to plan pre-boil volume for either system.

Pump, chiller and automation

KegLand builds the pump in. The Gen 4 35L Wi-Fi listing (B0B913WSZH) includes a built-in pump and a full-color LCD, the standard 35L listing names automatic step mashing, and the Wi-Fi model connects to the RAPT app and ships with a stainless immersion chiller. If you want to program a protein rest, a saccharification rest and a mash-out and walk away, the BrewZilla does it out of the box.

Anvil sells the pump as an option. The Foundry heats, holds temperature and offers a delayed start, but recirculation needs the pump bundle (B07SVCNRDT) or the separate pump kit. In exchange you get double-wall insulation, which holds mash temperature and speeds heating, and ultra-low watt density heaters that the maker says prevent scorching. There is no app listed for the Foundry.

  • Want app logging and RAPT integration with a RAPT Pill hydrometer: BrewZilla Wi-Fi model.
  • Want a simple controller and no electronics in the wort path unless you add them: Foundry without pump.
  • Want the pump and chiller in one box: Foundry 10.5 pump bundle or BrewZilla Wi-Fi model.

One more lineage note: KegLand sold earlier versions of this system as the Robobrew, and old Robobrew listings still appear. The Gen 4 is the current design; listings sometimes mix "Gen 3.1.1" and "Gen 4", so confirm the generation on the listing you open.

Who should choose which

Quick verdict by situation

Your situationAnvil FoundryBrewZilla
Only a 120V outlet, ever~ Works at 1600 W✓ Pump and step mash included
Planning a 240V circuit✓ Same unit, 2800 W~ Needs a different 220V model
Want app control and logging✗ None listed✓ RAPT Wi-Fi (Wi-Fi model)
Small 2.5–3 gal batches✓ Foundry 6.5✗ No small model in the catalogue
10–12 gal batches✗ Needs the 18 gal Foundry (not in the catalogue)✓ 65L on 220V
Strong beers near 1.080 at 5 gal~ 16 lb basket✓ 23.5 lb listed
Holding mash temperature in a cold garage✓ Double wall~ Insulation not listed

Pick the Anvil Foundry if you value a simple controller, insulation and the option to double your power with a 240V circuit later, or if you want the 6.5 for small batches. Pick the BrewZilla Gen 4 if you will stay on 120V and want the pump, automatic step mashing and Wi-Fi without buying add-ons.

Mistakes to avoid with either system

  1. Running it on an extension cord. At 12–13 A on 120V, cords and power strips heat up. Plug straight into a GFCI-protected outlet on the circuit your manual names.
  2. Assuming the Foundry is always on 240V speed. On 120V it is a 1600 W system; plan longer heat-up times or preheat strike water with a delayed start.
  3. Buying the wrong BrewZilla voltage. The 65L listing is 220V only. Check the voltage line before you order.
  4. Overfilling the grain basket. Respect the listed capacity (16 lb Foundry 10.5, 8 lb Foundry 6.5). A packed basket leads to slow recirculation and stuck mashes.
  5. Brewing with steam trapped in a closed garage. Open the door, use a fan or a steam condenser, and keep cords off the wet floor.
  6. Skipping the chiller plan. If your bundle has no chiller, budget for one; see immersion vs plate chillers.
Verdict

Anvil Foundry is the better buy if a 240V circuit is in your future or you want a small 6.5-gallon system: one unit, two power levels, double-wall insulation. KegLand BrewZilla Gen 4 is the better buy if you will stay on a 120V outlet and want the pump, automatic step mashing and Wi-Fi included. Both make about 5 gallons of finished beer and both need a GFCI-protected circuit.

How we chose

We compared the listing data for each ASIN with retailer spec pages and maker material (Anvil's listing and Q&A, KegLand's BrewZilla manual and product page). We did not brew with, install or measure either system. Where a figure is not listed, the table says so.

Questions

Anvil Foundry vs BrewZilla: which is better for a beginner?
For a first all-grain system on a 120V outlet, the BrewZilla Gen 4 35L includes the pump and automatic step mashing, so there is less to buy. The Anvil Foundry is simpler to clean without a pump and can move to 240V later. Both make about 5 gallons per batch.
Can you brew 10 gallons in an Anvil Foundry 10.5?
No. Anvil's Q&A answer is that the 10.5 is designed for 5-gallon (19 L) batches with up to 16 lb of grain, and that 10-gallon batches need the 18-gallon Foundry. For 10–12 gallons from KegLand, the BrewZilla 65L runs on 220V.
Should I run my all-in-one on 120V or 240V?
240V heats faster and boils harder: the Foundry 10.5 lists 2800 W on 240V vs 1600 W on 120V. If you don't have a 240V circuit, 120V works fine with longer heat-up times. Have a licensed electrician install any 240V circuit, typically with GFCI protection.
Do electric brewing systems need a GFCI outlet?
Use a GFCI-protected circuit for any electric brewing system, since water and electricity meet on brew day. Don't use extension cords, and follow the circuit rating in your manual. Our brewing systems hub shows the voltage of every system.
Is the BrewZilla the same as the Robobrew?
Robobrew was the earlier name for KegLand's BrewZilla line. Old Robobrew listings still exist, but the Gen 4 BrewZilla is the current design with a larger malt pipe and Wi-Fi on some models.
Does the Anvil Foundry come with a pump and chiller?
Only on bundles. The Foundry 10.5 pump bundle (B07SVCNRDT) includes a recirculation pump and a stainless immersion chiller; the standard 10.5 and 6.5 listings don't. Anvil also sells the pump kit separately.
