I will take a look- but where are you seeing “water volume”? The screenshots ask for wort volume.

I’m digging into this now.

 

The first thing I find is the calendar date picker once I click “brew it”. That seems ok.

Then all of my mash steps are in order. If yours are mixed up, can you provide a quick screenshot so I can see the problem?


Are you maybe sorting the steps? I am not, just using the default ones that I’ve added (like make this #1, etc). Here’s mine:


In the brew log, the calendar is gone on my iPad- but it’s easy to pick the date and time:


I see where the water volume entry is but that doesn’t seem to be an issue for me. It keeps track of the volumes. If that is a problem, I’m sure it can be changed. Why is that out of place there, though?

Last question (I promise!). My brew log entries are in the appropriate order but I can’t recreate your weird date order. Can you tell me how you got that, so I can recreate for a ticket?

Sorry to ask so many questions, but I really have to nail down each individual issue in order to submit a support ticket. I need to know what is disliked, what isn’t working well, how it happened, etc.

 

Gotcha! Thank you so much. I’ll dig into this and get a support ticket in right away.

 

When you say you couldn’t use the calendar/date picker, what did you see? On my iPad, I have a “rolling” date picker:


On my laptop, I have to click the little arrow (triangle):


And that brings up the calendar. Maybe that will help with the date picking.

The mash complete log should be showing water volume, as it's necessary to calculate the conversion efficiency correctly. It cannot be calculated accurately using only collected wort volume without making a lot of assumptions about your equipment and grain absorption rate.

However there should also be a line item for wort volume, for record keeping, that does not affect the conversion formula.

As far as the order, I believe the log order follows chronologically based on the timestamp, so if you enter boil complete first, then mash complete, it will show in reverse. This matches the image attached, since mash complete was logged the day before preboil complete.

 

Gotcha. The issue with the mash complete and volume is that it’s not clear from the tooltip and the efficiency explanation on what exactly it needs. The verbiage is very confusing, and the tool tip does not help.
You should be able to put the correct time in the brew log, as sometimes you add the data later on. Or am I misunderstanding your explanation?

 

Thanks for that- I need to know which computer platform and browser you were using when you got that screen. I can add that to the ticket.

 

Sure thing, it'll have to wait till I get home from work and I can walk through it and see if anything has changed since the Nov update that addressed this formula that I'm unaware of.

 

Recipe
https://www.brewersfriend.com/homebrew/recipe/calculator

12 lbs of malt, 37 PPG. Total points = 444.

Batch size is 5.5, 70% brewhouse is 311 points or 1.0565 og.

Strike water is 7.19 gallons. 100% conversion is 444 points, or 1.0561 og.

Mash runnings is 6.36 gallons at 1.0561, or 311 points.

This implies an apparent mash wort volume of 444 / 1.0561 = 7.915.

The additional 0.724... gallons is due to the sugars, proteins, and starches that are dissolved into the wort. The difference of 7.915-6.36=1.55 is the amount of wort that is trapped in the grain still.

Open the recipe and enter a mash complete log of 1.056 and volume of 7.19, you should get 99.8% conversion (due to rounding errors). Remember the apparent wort volume is 7.915, so 7.915 * 56 =443.24 points. 443.24/444 ~= 100%

If you enter the same mash complete for the first runnings of 6.36 gallons @ 1.056 (356 points). This gives 88% conversion.

There's no way, that I know of, toaccurately calculate the conversion efficiency without knowing the infusions volume without losing accuracy due to using expected absorption rate and mashtun loss instead to get the total amount of sugar in the mash wort.

 

Conversion should generally be 88-95%, 77% conversion indicates a notable pH or crush issue. 104% is a bit high though, can you link the recipe and your measure data? (total water used, temperature at measured volume, and sg). A reading above 100 probably indicates some sort of measurement or potential difference, maybe your base malt was 38 ppg instead of 37, or your total grain bill may have had a half pound extra, 1-2 oz's here and there add up, or maybe the total water is off by a quart, or some combination of the above.
