Trying out one of these for the first time today…https://shop.brewcraftusa.com/genesis-fermenter
Could be cool with a “no oxygen” transfer if you could pump air between the bag and the fermenter wall.
Not sure I follow you…what would be the benefit?
His thought is to blow plain air into the void between the fermenter and bladder to push the beer out vs pushing with co2 in contact with beer. Like a party pig keg
Based no looking at it, I don’t think that would work.
hmm, looking at it, and I gather it is a wide mouth plastic jug that comes with sanitary liner. After you ferment you just transfer the beer and chuck the liner?
It seems like if someone just sold sanitary liners you could use cheap Walmart plastic water jugs and get the same effect. What am I missing here?
If you were one of those LODO guys, you could transfer beer without introducing O2. The nice thing would be you could do this if you bottle conditioned, without having to invest in a CO2 setup. You’d also be able to do this at ground level, without moving the fermenter and shaking up trub.
I kind of imagine attaching a schrader (bike pump) valve on the side, and like Stevie said, pushing air into the void between the fermenter wall and the beer bag.
Looks like an interesting product, any idea on what the liners are going to cost? Looks like the fermenter is ~$60.
Hey Denny, so what is the idea behind this. Easy or no cleanup by using the bags, no sanitation required?
Looks like it will create a lot of landfill waste :-\ I’ll stick with my buckets and carboys
This looks like a piece of equipment designed for every short term homebrewer who brewed a couple batches, hated all the cleaning and immediately departed from the hobby. The problem with that concept is that there’s still every other piece of equipment to clean and a bucket is probably the single easiest piece to clean.
The gasket looks exactly like the one in the last Fast Ferment I bought, I’d be more surprised than not if it isn’t the same. Of the 4 variations on their gasket I have, it’s definitely the one that seals the best, but also the absolute worst one for staying in place inside the lid. The damn thing spent half of one ferment swimming in the beer!
You guys are missing the fact that you don’t have to use a liner…it’s optional. The fermenter itself is much heavier and oxygen impervious than a plastic water jug.
Tje gasket is specifically designed for the Genesis. They delayed the design until they could get that just right. It both seals well and stays in place.
I just don’t think that would work. I can,t see how the liquid would get pushed out when I stand here and look at it.
It would need a dip tube just like racking.
Fortunately, I remembered this is something Heineken came up with as a keg alternative.

You’d have to be able to seal between the bag and the fermenter wall, but that doesn’t seem impossible as long as you keep the pressure low. Hopefully that pic clears up what I’m talking about.
is it that much better than a better bottle?
It’s much heavier than a BB. Here’s a copy of a Facebook post from Brewcraft…
there is actually a dual layer of Polyethylene within the liner.
High Density Polyethylene (HDPE) and Linear Low Density Polyethylene (LLDPE) are essentially the same material but in different forms. HDPE has a more densely packed crystalline structure which gives it more rigidity so was selected for the shell of the Genesis, while LLDPE has a more ductile form factor which makes it perfect for the liner.
While the Liner is optional, it does come with the purchase of the Genesis (two of them actually). The liner is also IMO the preferred method of use, as it acts as an excellent oxygen barrier as well as eliminates the need to clean or sanitize the Genesis as it comes sanitary. There are also other uses for the liner such as transportation of liquid as it comes with a seal-able screw cap
hmm, cask ale straight from the liner maybe?
I think there is a market for people who want to minimize cleanup and sanitation. If you BIAB or extract, you don’t have a lot to clean on the hot side. There’s still kegs or bottles, but with a brewlock style keg feature you could single vessel ferment & serve.
The other part is something I feel like I see in products all the time, which is companies trying to convert from a up front purchase to a continued use cost model. Some business major looked at the printer market, and realized where all the money is at. Look at the Picobrew C/Pro, etc. You can only make so much money selling a brewing setup for $800. If you can lock people into buying 5 L brew kits for $25/ea, you can have a continuous revenue source.
The other thought that popped in my mind last night-great for trying out sour brewing. If you don’t want to worry about some brett lurking in a scratch, this’d be a little extra insurance.
