Grainfather!!

[2LiveBrewCrew]

Hi guy's, can someone please tell me what program to use to get my water calculations for my Grainfather? Do I use Grainfather's or BeerSmith2-3 or some other program? I'd like to get my machine up and brewing and it's the water amounts that are holding me back. Thanks guys. Cheers!

Hi. If you're just starting out, use the Grainfather website (or their app) to calculate the water requirements. Now they have a 110v option which should reduce the boil off loss and the numbers should come out closer. Keep good notes so the next time, you'll know if you hit your ferementer high or low. Also, I recommend you measure out all of your water (mash & sparge,) before you start. Heat all of it to strike temp, then pump off your sparge into another container (a water cooler works great to keep it hot.) That way, you don't have to do any measuring during the sparge. Hope this helps. Ed

Thanks ED. I'll sure take a look at it. I have the sparge water heater that I'll use. I'm looking at BeerSmith and they have a sale going on. Is that something to look at or should I just stick with Grainfather?

Beersmith is very good for building/managing recipes and lots of folks really like it. Personally, I use the supporter version of Brewer's Friend since it stores everything online and you can access your recipes from any PC. It also has a iOS and Android app for brewing. It's kind of a Ford vs Chevy argument which one is better. Personal taste and cost are the big things, but both work. You can also use the Grainfather website and app, especially if you have the Connect GF. It works well too, but I've found the recipe management on their website isn't as robust as either BR or BS. Hope this helps. Ed

I tend to make all of my recipes in BeerSmith, then I export them as BeerXML and import them to the Grainfather app shortly before brewing. This is partly because I've been using BeerSmith for many years and I'm used to it.

+1^^^ this, and I do the same with Brewer's Friend. I've found once you import it into GF, you really need to double check everything because it doesn't always come over exactly right, especially the units of measure (Imperial vs Metric.) Ed

 

[murphyslaw]

Same here. I build the recipe in BS then export to GF's website.

I use the GF app to automate the process steps and to remind me when to add things. But I use BS to tell me how much to add and to track my various measurements. I'm basically brewing from BS, so I don't worry about double checking the details.

 

[2LiveBrewCrew]

Thanks guy's. I appreciate the advice. I'm going to look into these programs and see which one works for me. Cheers!

 

[alestateyall]

I build my recipes on BeerSmith. I made my own Equipment profile that gets the same water amounts as GF.

I then use a GF Connect Quick Profile to run the GF. I have a single infusion profile. I just change the mash temp. I use the timers in BeerSmith.

I just transferred my 1st batch ( Belgian dubbel , homemade candi syrup ) , brewed using the Grainfather , to secondary fermentation. I just followed the operating instructions . I've been brewing for 25 years and as an apartment dweller I really enjoyed using the Grainfather. I was apprehensive about the 110 volts model poor boiling efficiency but I'm glad I purchased the graincoat insulation jacket. The only point I dislike is the fact that the bottom perforated plate seal get loose when installing the bottom perforated plate. To resume : I don't regret my purchase .

Hello everyone!



There is no problem, life has many interesting things



I have updated it with two more details if you are interested in seeing it:

http://www.jvilchesp.es/aficiones/cerveza/cerv_07/gf_04/index.html

And there are more things about G.F. here:

http://www.jvilchesp.es/aficiones/cerveza/cerv_07/index.html



Yes, it's mine, bought two months ago



Thanks, I did it with the help of the blacksmith of my small town and his machine



Time will tell us, sure. And if there is something special I will tell you right here, for sure.

Best regards

JC, from Spain

Thanks for taking the time to share your G.F. brewing event and work arounds. I'm new to the G.F. and appreciate your information.

My ghetto rig to prevent splashing during sparge... slowly ratchet it up throughout sparging process. Works like a charm, whether it makes a difference???

Also saves your back when removing the basket.

To make it easier to push down the bottom plate keeping the seal on do this:

Open your crushed grain bag and put the mash cylinder without the plate pushed down in the bag. Take some grain and rub down the inner surface of the cylinder. The grain dust will lightly coat the cylinder making it super easy to push down the bottom plate with seal in place. Cheers

I have used my GrainFather for a while now with no issues.
The heating element attached to the bottom of the pot has two elements ... a inner and a outer and for high or Boil setting both elements are active. They are horseshoe shaped not a full circle. The elements are inside a metal plate that is epoxied to the bottom of the pot and thus are not replaceable ... I talked with the manufacture about that and replacement of the entire kettle is the only option from them.
As to the pump problem it sounds like a faulty pump impeller.
I have never had an issue with the one I have so I never have taken it apart.

The only problems I have ever had is using Flaked corn as it tends to "stick" the grain bed so I can not recirculate during mash. I did remove the spring and ball from the pipe joint just above the red valve because it became blocked with a grain hull once ... no problems since. From mash temp to boil it does take a while but that gives me time to drink a homebrew and do grain basket clean up and fermenter prep. During boil I move the glass lid slightly askew to allow more steam to escape and prevent the dreaded boil over ... I dont get a good rolling boil with the lid off. (5.5 gallon batches)

Anyhow ... I would highly recommend the Grainfather to anyone wanting to do 5 or 6 gallon batches of all grain. Their Chiller is the NUT!

Can I ask why splashing during sparging is an issue?

Can't speak for the other poster, but I'd say it's to do with reducing oxidation exposure.

If you have come across any of the LoDo threads you'll find some people believe it's a thing and some don't. The LoDo folk will go to considerable extremes to avoid oxygen intake in the mash and kettle. Other folk don't care at all. This approach of avoiding splashing is somewhere in between.

For what it's worth, I believe that hot side aeration is a thing, and didn't like that the Grainfather overflow pipe was continually splashing my wort during the recirculation. So I removed the overflow pipe, use a BIAB bag to contain the grain in the basket, and put a clamp on the hose to reduce the recirculation speed. This helps avoid splashing, which may or may not be beneficial to the end product.

I don’t understand the stuck during recirculating... the only time you would ever get a stuck bed is during sparge when the grain bed starts to compact. You could do 100 rye and it would stick during recirculating. I think something else happened there. I’ve never had a stuck mash ever with the GF. 60% Wheat no problem. You never need rice hulls in my opinion. Yes you might have a slower sparge but as you will see that’s how you can get max efficiency with your GF.

Also there is plenty of evidence out there that a rolling boil might actually be more detrimental than beneficial. I’ve actually started turning my boil down to minimize boil off.

Well here is the deal ... The wort is recirculated during mash and the level rises until it is flowing into the overflow tube instead of thru the grain bed. This can be a problem as pits and pieces of grain will flow down that tube and either block the pump filter screen or flow up the tube and block the check valve.
If you have never had that happen then you must never used much flaked corn as it happens every time I use it. I need to stand there watching it and turn the pump off and wait till it drains down then turn the pump back on till it happens again.

You can use a sink strainer over the overflow pipe and also dial back the pump via the valve.

 

[couchsending]

Just close the valve at the top slightly to slow the flow so it doesn’t go over the overflow or only does just slightly. I have to do it on maybe 60% of my brews.

What am I doing wrong? I hit my preboil gravity (estimated in Brewers friend). However, I'm always short of my OG after 60 min boil. Today's target is 1.059, but I'm only at 1.050. Now I'm boiling down longer to get there, but it messes with my SRM. I've done 2 boil off tests with water and got 1.875 qt/hour both times. ANY IDEAS?

what was your preboil gravity? You usually only get 5-6 gravity points with a 60 minute boil. if target was 1.059 your preboil gravity would probably be around 1.053ish?

 

[skleice]

Preboil was 1.040 (estimated was 1.036). Clearly I'm messing up on my water calcs somewhere. I'm overshooting volume too.

Edit - I'm still struggling with dialing my water volumes, but this issue seems to be my refractometer. In other words, I'm a dummy and didn't make sure my refractometer was calibrated.

Looking to purchase a grainfather for the ease of a "pilot system". Who has the best deals? What accessories do you all recommend that are musts?!!

Keep an eye out for Northern Brewer 20% off + free shipping.

I would recommend a graincoat. If you plan to do small batches, the micropipe is also good to have.

Wait, did I read that correctly? You want to get from a pre-boil 1.040 to a post boil 1.059?? Unless you're adding some sugar during the boil, good luck with that. I've never heard of anyone moving the gravity that much, mine is 4-7pts max in 60 min boil. If you've done such a thing previously, or heard of someone who has, I'd love to hear about it. I record my gravities, and just checked. 7 max I saw in review.

Edit- Ha! I'm dummy, didn't read your edit!!

 

[doogster]

I'm not gonna lie I'm a few brews in and didn't read your whole post, bit when I had to my pump replaced I had the same issue. Something happened with the pump and a piece expanded inside when it got too hot and wouldn't allow anything through. You should contact GF directly and they will send you a new pump.

Hey there..

Unreal. I think I have the same issue. Last batch (my 20th on the GF), which was not highly hopped... the pump failed during chilling... so I had to drop an immersion chiller in there to cool and then siphon out the wort. Later during cleaning... the pump worked just fine.

I am going to do the water only boil/pump test and see if I have the same issue.

I think the lid is only supposed to be used during mash and totally removed for boiling. I left it on for the boil once and gave myself a nice burn when I put my finger through the hole to use it as a hook to remove the lid. I now boil without it which also makes for easier additions during the boil.

Correct, you want the kettle wide open for the boil. You need to drive off certain volatile compounds (like DMS), and if the lid is in place, they can condensate back into the wort.
And you're trying to lose some water/increase gravity
And that sucker gets hot, which you "fingered" out ;Þ
