BH efficency seems to go up a few points with lighter beers (lagers). This seams to work out almost perfectly for me.hope it works for you too.tweak boil off as you see fit. then create a mash profile to however you want to mash, but make the mash step with a water/grain ratio of 2.72 l/kg go into advanced option (see attached pic called GrainAbsorption for details) and change the grain absorption from 0.96 to 0.77Ģ. Use 60min profile for 60min, and 90 for 90min.ġ. One for 60min, and one for 90min, see attached picture called (profiles) for details on each. Setup up 3 things and the calcs should work out.įirst - Setup two equipment profiles. Apart from above 7.5kg of grain, where Grainfathers online mash/sparge water calc seems to go wrong, as the mash water drops with more grain, which seems incorrect to me, so must be a stuff up from them Im thinking. I found the below to work out almost perfectly for me everytime. You'll have to make a compromise somewhere But unless you are very lucky, you will never entirely match BS2 (also, it uses different equations and assumptions). The files I've linked will get you there. There are lots of people happy with the GF calcs and values - that is fine. Start with the ballpark figures and fine tune to your own system to account for variability in manufacturing of the GF, element, chiller, amount of hops (and absorption), grain absorption, power supply, altitude, etc, etc. But if you know your own conditions and timing, you'll know that you need to leave 40 mins (say) before work (I can't stand being late - 'early is on time, on time is late and late is unacceptable') and have x litres of fuel in the car.

Although google maps says it takes 20 mins, one day it might be 18, another 25, another 23, another 15, who knows? And each trip will affect the fuel you consume, even though the route and distance may be the same. Other cars, holiday traffic, rain, car accidents will change things slightly. While the car might be the same each day, other factors that are out of your control will influence the time it takes. It's like driving a car from point A to B. Noting and recording this, I have moved away from these standard calculations and am dialling my own system to reflect what I see. You need to change the absorption in Options, and the water grain ratio in each mash profile you are using.ĭespite being able to force BS2 calculate the mash and sparge volumes, other variances in your own system (due to location, etc as mentioned above) will influence the variables from then on. If you want a profile that will make it work, I have uploaded them here (my machine is in Australia, running of a 240v system). You'll even see on the GF website there are different calculations for the voltage of the machine you have - that is even though everything else about the equipment is the same (eg geometry, surface area), and boiling point doesn't change (at your standard location/altitude). Boil-off changes with altitude, absolute temperature, humidity, etc. In reality, I think that what I was trying to do was force BS2 to fit the standard GF calculations, rather than tailoring it to my machine. Oginme and Brewfun have had to deal with a heap of my questions. I do own a grainfather, and I think Oginme's response is perfect. Personally, I would not try to make the profile match the Grainfather calculator, but using the information from the calculator make a recipe and then use the actual information to adjust the BeerSmith profile to match my results.

Others may transfer the full amount of 11 liters (leading to the same water usage) or may make and transfer only 10 liters (leading to a different water demand, extraction efficiency, etc.) For example, I plan on 11 liter batches and transfer 10 liters to my carboy. No simple calculator can account for these changes and, therefore, some personalization of profiles needs to be done in most cases to make the profile match your particular brewing method and materials.Īdd to that, some people may leave behind more wort than others when they fill their fermentor. These things have an impact on the amount of water which is retained in the spent grains and the effectiveness of removing the starches which are then converted to sugars. The grain you use, the crush of it, the care of mashing in, grain removal and wort drainage are all variables to the machine. Water should be pretty straight forward, but when it comes to the grain things become non-standard. While the equipment may be standardized, the other process inputs (grain, water) are not. Disclaimer: I do not own a grainfather, but think my response may help.
