    Does anyone know of, and/or have any experience with any complete home brew system such as Braumeister or GrainFather that specifically works for lagers? Either as a complete system, or a partial fermentation/lagering system (like the Bretech Unitank) that works outside of a keezer.

    Obviously, such a system must have a glycol jacket of sorts, for fermentation/lagering, unless there are other ingenious solutions.

    Not sure what you mean. I have a 50l+ and a 20L+ that I use for R&D purposes that I got from Braumeister for developing parts for them (hint the new low oxygen brewing kit!). What exactly are you looking for?

    I'm developing some serious arthritis in my hands, and soon won't be able to lift heavy objects too easily. I was therefore thinking of maybe selling all my current brewing equipment and purchasing an indoor standalone system such as Braumeister or GrainFather, where heavy lifting is not involved, and one can still brew 5 or 10 gallon batches.

    Unfortunately, these systems only ferment at room temperature, and are thus specifically designed for ales rather than lagers. Since I mostly brew lagers, these standalone systems would not work for me. Thus I was wondering, ideally, if anyone knew of any complete standalone lager systems (i.e. mashing, boiling and fermenting). Alternatively, just the fermenting component might also work, especially in a closed, conical system (yes, to assist with a low oxygen approach).

    Since the conical systems are too large to fit in a keezer, I was wondering if the industry had considered the needs of lager brewers, and whether such a system had already been designed. Since the fermentation system would have to have the capability of cooling down to steady lager fermentation temperatures (e.g. about 45-52 F), it would likely need some sort of circulating, glycol cooling system in a jacket surrounding the fermenter, or a circulation system that circulates through a cooling device (which would likely be much less efficient). I have not been able to find such a system. So, unless I do, I might eventually have to give up on homebrewing altogether, or move to 2.5 gallon batches.

    Hrmm..

    The BM is the brewing system. Not the fermenter, same with the Grain father.

    You still need to be able to lift (I use an electric winch) the grain basket, and then be able to transfer to a fermenter (but they have pumps).

    Conical will certainly be able to fit in chest freezers and fridges, especially the 5g ones.

    If you are talking something that mashes, boils, AND ferments all in one connected system, I'm not sure I have ever seen anythng like that either.

    Now if you were to take one of those hot side systems, like the Grainfather, and combined it with a fermentor like this from SS brewtech- https://www.ssbrewtech.com/pages/chronical-brewmaster-edition - which cools with a coil, transferring between the two with a pump, would that be in line with what you thinking?

    The coil attachment would be cheaper than glycop jacketed, I would think (though they have those as well). You could also get a standup fridge that fits a conical. Again, pumps would be your biggest tool. Cleaning could be an issue though.

    Then you still have to get the beer from fermentor to keg. If you wanted to skip that, and blow a ton of money at the same time, I guess there is always this - https://wlabsinnovations.com/products/vessi-fermentor-dispenser - though they are sold out, probably not a good sign for that company.

    Well, that stinks. Net searching certainly didn't return a genuine all-in-one single-vessel solution.

    If your brewhouse has relatively level and smooth access to the outside would it be feasible to get a fermentor with a wheel kit and a warming jacket* then move it outside during the colder months, maybe even to a small insulated hut to keep the wind at bay and help prevent it getting too cold? But that's not a year-round fix and you'd still be relegated to small batches in the warmer months.
    Looking for a silver lining, smaller batches might rekindle some creativity for experimentation.

    I'm optimistic there's a solution, even if it doesn't jibe with your current visualization.

    *I realize the GrainCoat is for straight-sided vessel. Without knowing your threshold for expenditures, the concept behind this contraption might work as it specifically mentions "it can get to and hold lager fermentation temperatures of 48-52°F".

    Certainly Ontario is conducive to brewing lagers in small batches in the winter...maybe split batches between 2 fermenters to make moving them easier.

    Yes, that's what I meant - either the entire system or a partial system (e.g. conical) might work. Indeed, the lifting could be easily accomplished with a winch of sorts.

    As for the conical, unfortunately, as mentioned above, it won't fit in most standard freezers. The Brewtech 14 gallon Unitank is 42.5 inches tall. I only have 19 inches of room in my freezer.

    Yes, the 14 gallon Bretech Unitank is exactly the system I mentioned in my first post. However, the cooling system is for cooling the wort, and wouldn't really work for keeping the wort at, say 45 F for weeks on end. The cooling system is like a wort chiller, and the amount and cost of ice water to keep it at that temperature for that length of time would be quite high.

    I have not seen the glycol jacketed version. That's what i was looking for. The 14 gallon Brewtech might just fir into an upright fridge, although it will likely be quite tight. I will look into that as an option. Of course, the main problem would be lifting it into and out of the fridge for filling, cleaning, etc.

    Draining from the fermenter to a keg will not be an issue. The keg is not quite as heavy as the boiler or fermenter, and a keg could easily be put on a cart for moving around. Then a pulley system could be used to lift it into the keezer if necessary.

    No, most of my stuff including the keezer is in the basement, and I usually brew outdooors, which is a flight up and then some ways to the front of the garage. I had thought about your suggestion of using a heating jacket in the winter, but that's not a year-round solution, and sometimes the weather can change suddenly, even in the winter, leaving the fermenter too warm.

    [quoteLooking for a silver lining, smaller batches might rekindle some creativity for experimentation.[/quote]
    Yes, this is becoming more and more a likely solution, although I'm not ready to give up yet.

    Yes! Thank you! This is more in line of what I was hoping to find (at least as part of the system)! I will have to look further into this and see how the cooling system actually works.

    Yes, indeed it is. Small batches is the solution that I might have to end up with, but I am still hopeful that a better solution is out there. It takes a lot of extra work and management (e.g. yeast and temperature management) to do small batches almost simultaneously (especially when you only have one temperature controlled freezer to control several batches on different timelines), so it is a last solution.

    The Brewers Edge Mash & Boil has a fermentation lid that allows you to do this all in one vessel. However, @OldBrewer would still have to lift the grain basket and come up with a temperature solution.

    Right, you did, oops. For some reason I thought they were jacketed, but they do sell a separate glycol unit.

    I had thought someone actually told me they rigged it to circulate cold water from their keezer, but I'm not sure of the logistics or efficiency.

    I have a Stouts fermentor that fits in an old Pepsi fridge, but you are right about the moving around to clean and such.

    Paraphrased from a description of the double-walled Grainfather Conical Pro:
    The cavity between the walls has a 30 Watt, 12V heating element. The element heats the space between the walls, transferring the heat to the inner wall and then to the beer.
    In between the two stainless steel walls sits a liquid cooling sleeve. The outer walls have ½” female threaded outlets and inlets for installing hose barbs that run to/from a water pump or glycol chiller.
    The double-wall design makes it easy to clean because the interior of the fermentor is smooth....no protrusions inside because the ½” females are made into the outside wall.

    8-gallon capacity....plenty for 5- but way short of 10-gallons (you'd hafta get two).

    Not many reviews around, and the two I did find complained about things that could be related to “getting the bugs worked out” of a new product

    I have the SS Brewtech 7G Unitank with standard FTSs (run from a 10G cooler and frozen water bottles) This system will not keep 5-6 gallons down to correct lager fermentation temps. I can’t imagine trying to control bigger batch sizes without a chamber to put it in. I think the FTSs is only good for maintaining temps 10f lower than ambient. Certainly won’t let you get anywhere near cold crash/ lager temps for a meaningful length of time. What you’ll need is the FTSs + Glycol unit they sell - but it’s spendy.

    It weighs an absolute ton empty and is a bit of pig to move around without casters. They’re quite compact and will fit in an upright freezer, but again bit of a pain getting it in and out. (Could fill via pump from BK and use a CIP attachment to minimise this)

    Other than those points it’s excellent. The Braumiester also looks like a great bit of kit. There’s a guy on YouTube with some excellent brew day videos with his in action. I think he has an electric pulley set up to lift the grain basket. Makes brew day seem effortless.

    It has a couple of limitations though. It’s a long time since I looked into buying one so I may be incorrect. I think the malt pipe won’t hold enough grain to produce wort over a certain gravity (guessing 1.070 from memory) If that’s an issue for a huge doppelbock or whatever you might have to reiterated mash or carry out a long boil to get round this. If you like to vary your batch size, 5G and 10G - I don’t think you can produce a smaller amount of wort without buying the additional short pipe. Something to do with the way in which the pump flows up over the heating element and grain.

    The glycol cooler idea might work. It's something I'll have to look into. I don't mind just doing 5 gallon batches.

    I can live with making 5 gallon batches, and beers with more average gravities (especially since most will be the more pale lagers.

    The other option I've looked into are Peltier thermoelectric coolers with heat sinks, but I hear that they're not too efficient and run up quite the electrical bill. A friend has the Braumeister and loves it. He places it in his cold cellar during the winter to make lagers, but is not able to control the temperatures steadily. His lagers don't turn out too good.

    As for the glycol system, as you say, it's quite pricey. Thus the most practical option seems to be an upright fridge or cooler to serve as a cold chamber. With that, I would need a hoist system to get the SS Brewtech out for cleaning, etc. Of course I'm still left with dealing with the mashing and boiling vessels.

    All in all, I very much appreciate all the creative suggestions offered in this thread, although currently there does not yet seem to be any optimal solutions, especially with regard to the entire operation.

    It sounds like the braumiester and a pulley system could fill your wort making needs. For fermentation, if you don’t mind dropping to just less than 5G batches you could look into using corny kegs. They’d be easier to move in and out of a stand up freezer and still allow fermenting under pressure/ closed transfers to keep oxygen out. Head space needed for a lager under pressure is minimal. If you only racked the cleanest of wort to the keg your trub losses should be pretty negligible.

    Thanks, that's good advice. I wish they made 23 liter kegs. That would be ideal for fermentation, and allow lots of head-room. But as you say, lagers fermenting at 45 F don't need quite as much head room.
