    I'm brewing an IPA this weekend, and the recipe calls for 0.75lb of corn sugar.

    I was planning on using an equal amount of table sugar instead. Both are 100% fermentable, so it shouldn't make a difference, right?

    Also, is there anything I should know about swapping them out (like whether to use equal weights)? When I changed the recipe on Hopville from corn sugar to table sugar, the OG stayed the same.

    Won't make a difference. They are interchangeable.

    Same thing. use interchangeably. I stopped buying corn sugar years ago.

    That's what I thought. Just wanted to be sure. Thanks!

    Corn sugar normally contains a small amount of water, but it's pretty insignificant. That's probably why hopville treats them the same. I would not hesitate to use table sugar instead of corn sugar. 1:1 is close enough. Technically, the yeast have to do slightly more work to use table sugar, but I doubt it would have a noticeable effect.

    The yeast have to invert the table sugar, but in IPA amounts, I would agree, no big deal. When you start getting into tripel/Duvel ranges of sugar, than I would certainly advocate using corn sugar.

    Interesting. I had no idea. Thanks for the info!

    The boiling done to dissolve table sugar into solution, not to mention sanitize it, will invert the sugar. Most of it anyhow.

    I always use corn sugar.... not sure why, but it seems like the better choice.

    Actually corn sugar is dextrose and table sugar is sucrose which has a slightly higher fermentable index.That's because when converted into monosaccharides a molecule of water is incorporated so you get a little bit more!
    Bear in mind that table sugar is free.You can steal it from housekeeping :slight_smile:

    I think you get 1-2% more carbonation from the same weight of table sugar; most of us don't measure that closely anyway. Table sugar is so cheap in the US it might as well be free, well under $0.50 per lb.
