    I get two different attenuation figures using the recipe builder and the abv calc tool. The recipe builder doesn't seem to be calculating attenuation correctly. When I enter a custom value of 83% it is actually calculating for 90%.

    OG of 1.081 and FG of 1.008
    recipe builder shows - 83% aa (not correct)
    abv calc shows - 90% aa

    We're checking into this. Do you happen to be able to show a screenshot of both, so we can see what you're looking at?

    Great- thanks. First, can you check "late addition" with the sugar, as it's not mashed. It might not change it correctly, but it might.

    Checking/unchecking that box only changes my IBU figures.

    Only seems to be affecting this recipe...

    Hmmmm- can you give me the link to the recipe and the calc page, and I'll take a look?

    If I delete the sugar and re add it custom, it seems to correct it. Unfortunately, it won't save the changes now.

    It won't save the new custom attenuation?

    It won't save the recipe. If I go to edit it again, the custom sugar addition is gone with the default one back.

    Just for reference the default entry for cane sugar gives me a FG of 1.007. When I delete it and put in a custom field with the same figures, the FG is 1.010 which is correct considering the entry for attenuation.

    Can you show a couple of screenshots, so I can try to recreate the issue (so we can fix it!)?

    When I view the recipe:

    When I edit the recipe:
    upload_2019-5-28_7-38-30.png

    Attenuation is set to 85% for both scenarios.
