    Hello!
    Am curious as to why the same recipe created in September and copied in December would show such different stats:
    Recipe:
    7 lb 2-row
    6 oz Crystal 40
    1 oz Chinook hop
    1 oz Perle hop
    2 oz Cascade hop (dry)
    Yeast Safale US-05

    Stats Sept 2019/Dec 2019
    OG 1.038/1.054
    FG 1.007/1.010
    ABV 4.11%/5.87%
    IBU 73.94/94.76
    SRM 4.82/6.15

    I can’t open those- can you give me a link to the recipes so I can take a look?

    Does this work for you?

    The efficiency in one recipe is 65% and in the other is 70%. That changes the boil gravity, the extraction, the OG, etc.

    However the difference of 5 % is about 13-14 total gravity points, or ~2-3 SG for the batch size. It's not enough to explain the 16 SG difference.

    I agree that the efficiency change will impact the calculated outcome, but not by as much as is indicated in the two recipe printouts.
    Still wondering...

    IF you post a link to the recipe, I can look at it more in-depth. I can’t tell any thing else from the screenshots.

    Be happy to with your help. Thought BeerXML could not figure out how to use a URL to access the link. Suggestions?

    On the recipe editor, click the toggle for share recipe so your recipe is public, then copy and paste the URL from the browser.

    When you are looking at the recipe, click and highlight the address in the address box and copy it. Then paste it here in a message. Then I can see it, and figure out where the differences are.

    I'm not seeing the 1.054 in either of those recipes, or in the brew sessions for those recipes.

    They're all 1.034-1.038 which is within the efficiency differences in the two recipes.

    The maximum potential of this grains is 7* 37 + 34 * 6/16 = 271 points.

    271 * 0.70 (efficiency) = 190.

    190 / 5 gallons is 38. Or 1.038.

    I'm not sure if there was an error in the old recipes, but in order to get 1.054 you would have to get 100% efficiency (271/5 =54.2).

    It’s hard to go back and forth, so this is sort of piecemeal the way I am explaining, so I’m sorry for that. In the first example, you have a higher preboil gravity than the OG. That is because you have a post boil volume of 3.5 gallons, so it looks like you added water to get to your actual post boil volume of 5 gallons. . See screenshots:

    1F2F11E3-F1D5-4EC4-8F1B-CB1261653DF3.jpeg 8BFFC2D7-51BD-45EE-8F27-E21A80968C7C.jpeg

    In the second recipe, you did the same, but with 70% efficiency. By adding 1.5 gallons of water, you lower the OG. Increasing the efficiency of the mash/lauter changes the numbers so you got 1.038 instead for the OG.

    I didn’t see the recipe with the OG of 1.054 (you did not provide a link to that one), but if you corrected the volumes to give you a finished 5 gallon batch of wort, and didn’t add 1.5 gallons of water, that would then give you the higher OG.

    Does that make sense?

    I see your point. Thank you for the information. Tom
