Awesome work AJ. I've been playing around but haven't had a chance to dive that deeply. Definitely adding this to my to do list.

See this may not be much better. In general the measurmental uncertainty is going to be half the smallest unit that's marked. So lets say you're filling your pitcher 9 times for the example of 37 qts for mash water, and it's only as accurate as a cup, this gives your re-marked fermenter bucket...

Aside from different grains absorbing different amounts, and having different kernel densities, there's thermal expansion which can realistically account for an additional 2-2.5% of your water volume at mash temps. At this point we're still missing ~4 qts in your example @andy6026. I'd have to...

Above post should be for @VirginiaHops1. I'm the developer for the previously mentioned software

I'm super excited about this. Once I have some free time, I'll definitely be working on a port to JS / JSON for a web app, and including it in my software if I ever end up releasing it. If anyone is interested in following along, contributing etc, send me a PM and when I get to it I'll send...

Love you guys. Thanks for the recommendations! As always, if anyone ever has any suggestions, comments, etc. Feel free to drop one in my inbox, email, github repo, etc.

I'll have to read through this a few times, but I will volunteer to help implement a web based version if there is interest. I've taken a few courses in chemistry, but my degrees in math and physics research, not chemistry. Can start a git repo for this so it's free, open source, and available...

It can be locked to the creator and to a list of individuals the creator chooses.

Sounds awesome. I'm glad to see this gain some traction, looking forward to the release and seeing what you put together. Have you considered google sheets? It uses javascript instead of VBA, has sheets web api, and has addons that can mimic solver (linear, and non linear). Also it's free, and...

yield = 79% fine, 77.5% coarse, potential should be ~36.35 PPG (or SG).

Looks interesting, but a bit difficult to follow since you refer to other posts without saying where they are or providing a link or quote. If this is to stay a sticky post, I think those need to be added.

bs2 calculates mash efficiency based on brewhouse efficiecny and kettle / chiller trub losses. If you need to change your mash efficiency, then you need to adjust one of those two variables.

Thanks! Most of the small differences arise from the fact that beersmith and I don't agree on where volumetric thermal expansion should be displayed (wort and water expands when heated). Beersmith only applies it to boiling liquids. This may become an optional feature in my next release. If you...

Thanks for the plugs everyone. If anyone ever has any issues, suggestions, or comments, let me know! You can message me here, or at gmail through my website.

The numbers look good. Conversion is in a typical range at 90-94%. The first set is a bit uncertain though, as mash eff % is lower than brewhouse. Brewhouse should always be lower than mash, as the only difference is kettle losses. Most likely your volume measurement was off slightly.

Hello again, So if you're looking for the *correct* method, then dougs spreadsheet (using braukaisers formulas) are the right way. However they're also a bit convoluted to follow. Here's a link to another google sheet with some simplified formulas using gravity and WORT volume, what I'm...

Unfortunately, brewersfriend is using an inaccurate formula as it's calculated from strike volume and grain bill, and doesn't account for the volume of the increased wort from the dissolved sugars/starches/protein. It always reads lower then it actually is, IIRC it's something like ~8% lower...

Double crushing is worthwhile if the initial crush is inadequate. You can only get so much conversion though, and most decent crushes yield 90-95% conversion efficiency, so if you're already in that range, then double crushing is unlikely to benefit much. Double crushing is not some magic...

Measure the conversion efficiency next time, it's a better metric for grain crush, since mash/brewhouse also involves sparging, equipment losses, and how much grain is in the recipe. Conversion efficiency removes all those variabels.
