Some of them even label themselves as Keurig or Nescafe-type devices.

I still consider it “less than brewing” when I see advertisements for pod-based systems. Without knowing the exact Grainfather process, I may have even considered it “cheating” to use an all-in-one system like this. You can see an example of that on my YouTube channel while adding a ball valve to my brew kettle. It flies in the face of the DIY nature I’ve always employed while adding equipment. I was even a bit embarrassed to tell people I was brewing on one. I felt no obligation to make a positive or negative review. These are my thoughts and are not necessarily the views of Grainfather or anyone else. Again, I’ll start by mentioning that I was skeptical. I mention all that in the interest of honest disclosure. No other compensation was offered, asked for, or accepted, and I’m returning the Grainfather upon completion. In exchange, I’m making this video to explain my impressions. They connected me with a helpful rep who provided one to try. So I was skeptical of all-in-one brewery units and asked Grainfather for help trying one. I was getting good efficiency and good results.

I fly-sparged with an Igloo water-dispensing-type cooler from Lowes and a DIY CPVC sparge manifold. I’ve been brewing outside for 6 years and the vast majority of the beers I’ve made were 10 gallon batches on a gravity fed system with a Coleman X-Treme mash tun and a DIY copper manifold into a 15 gallon kettle from Restaurant Depot. So the shrinkage is 1.The Grainfather showing all included equipment.
#Grainfather beersmith plus
(23+2.5)*4% gives shrinkage of 1.02 litres plus 3.5 evap so 23+2.5+1.02+3.5=30.02 I may be confused hereĪny minute now I am going to feel a right idiot I am working the 4% shrinkage out after the evaporation of 3.5litres, was never good at maths at school and that was an awful long time ago. We are a liter adrift for some reason, not sure I follow the /.96 bit? I am working on a 50ml evap per minute which should equate to 3l an hour in the boil, so I can have the boil time as a variable on the spreadsheet. So for a bigger brew I would need to hold back from the sparge the litres over 30 in the preboil vol to add during the boil? I've raised this issue with them on numerous occasions but up until now they seem content to ignore me.ĭave, I have just knocked a spreadsheet up using your numbers, seems correct using your 27 litre and 90 minute boil, can you just check the figures I have got for a 23 litre brew and 70 minute boil.Īdding sparge and mash vol gives me my total liquor? 35.52 litres? I use these values every time and my brew length in the FV is almost always bang on. Pre-boil vol - Mash vol + (grain weight x 1.1). This amount will not fit in the GF all at once so I keep a little back and add during the boil. I usually do 27L brews with a 90 minute boil, so my pre-boil is:-Ģ7 + 2.5(dead space, not GF's value of 2) + 4.5 (3L per hour evaporation) + 1.2 (4% post-boil shrinkage) = 35.2L. That will not change for a given brew length and boil time. First work out what your pre-boil volume should be. Consequently I always calculate my Sparge volume manually and ignore the GF calculation. It also doesn't take into account shrinkage due to post-boil cooling. That, in my experience is nearer 2.5L, probably due to losses in the CFC and it will vary in any case depending on how many hops are used. It should be 1.1, and the figure of 2L for dead space is also wrong. As mentioned above, 0.8 used for grain absorption is wrong. The GF calculation for Sparge volume is incorrect. Then with deadspace etc I am left with 22l in the fermenter. So after boil volume is something like 25l. I think the max volume the grainfather holds is 30l but that would be to the top I think a resonable max boil volume is 27l which takes into account the hot break when coming to boil. Although i have stopped using beersmith and just use the grainfather to create the recipe then this is then available on the grainfather connect app ready for sending to the grainfather (dont know if you already do this, appologies if you do )
#Grainfather beersmith software
I take it you mean beersmith? With that software you can indeed set it up for a grainfather and you could also address the issue with the absorbtion rate (this is easily changed in beer smith). Tried the Brewsmith trial, but couldn't really work out what it was telling me as total liquor was around 40 litres Thanks, its only the first brew and first non kit experience, so early days, just trying to work out how I get bigger FV quantity, I have 30l kegs to fill so 27 litres in the FV would be a good target.
