DigiMash Unboxing

Our beer-brewing equipment arrived today! The packaging was not robust — every box had some fairly substantial damage. There’s a dent inside the kettle and one of the fermenters has a pushed in section (supposedly this will pop right out when we fill it). My first surprise was that we got a DigiBoil in a box and the mash upgrade kit in another box. The kettle is even branded as DigiBoil. Which … from a manufacturing / material standpoint makes sense. Why would they have two different sets of packaging and product labels? And three different SKU’s — DigiBoil, DigiMash kit, DigiBoil Mash Upgrade. It was a better deal buying the DigiBoil package — the DigiMash 65L was $259.99 and the mash upgrade $89.99, so we saved ten bucks ordering

Electric Brewing Research

We saw a DigiBoil at the local homebrew shop when we stopped by to pick up yeast. Scott had been pricing out a three-kettle system with pumps (along with some sort of table) and it wasn’t cheap. The DigiBoil was about 200 bucks. I took a quick picture of it to research later. Quickly discounted it as an option because it’s just a big pot with electric elements to boil water. We needed something for mashing too.

At which point we decided to shop around and see what other options were available. There’s the Grainfather — super expensive and, if I wanted to walk away while it cooked, I’d want to go farther than Bluetooth range. We came across Brewzilla — the software controls of a Grainfather minus connectivity, but 650 bucks is a lot more reasonable for a 65L brewing platform. Unfortunately, the 3.1 version starts the timer when the elements kick in to reach that temperature. Version 3.1.1 systems change this logic so the timer starts once the temperature is reached. The control board can be swapped out, but I really don’t want to blow fifty bucks upgrading something I bought this week. And, while there were some 65L 3.1.1 Brewzilla’s hit the US at the start of 2020, suppliers are all awaiting delivery “late summer 2020”, “late September 2020”, or “Autumn 2020” … which I took to mean “we don’t know when”. Understandable, but pretty much put the Brewzilla out of the running.

I came across a Mash & Boil — a 35L system with re-circulation pump is about 350. Decent price, but there’s no 65L system. Same with the Anvil Foundry — where a 6.5 and 10.5 system are available.

In looking at the Brewzilla, I found a mash upgrade kit for the DigiBoil. And a kit which includes both the mash upgrade and DigiBoil called a DigiMash. Both a 120V and a 240V 35L DigiMash are available, as well as a 240V 65L system. At around 240 bucks for the 240V 35L system, it’s a great deal compared to a three-kettle system. Because we frequently do double batches and potentially recipes with larger grainbills, the 18 pound capacity was limiting. At 340 bucks for the 65L DigiMash, it sounded like a great deal. No re-circulation pump, but it’s easy enough to hook a pump up to the output valve. Brewzilla has a port in the bottom of the vessel that goes down to a pump under the unit — a short silicone tube connects to the pot and another short silicone tube that connects to the metal fitting through the side-wall of the vessel. On the video we found, that tube was pretty cruddy looking … which isn’t exactly a selling point.

DigiMash doesn’t have the software-control of Brewzilla — you can set a 158F mash temp and come back and hour later, but you cannot perform step mashing. Which … not something we’ve done. And, really, you could. You’d just have to change the temps manually. It sounds like an interesting experiment to put together an ESP12e and a few relays to control the elements. Potentially, we could turn the DigiMash into an open source customizable controllable (and WiFi connected) brewing system.
