Drunkenly made a batch of alcoholic ginger beer on Sunday. I took the OG but neglected to write it down. I've taken a hydrometer reading today and it is sitting at 1.014. There is still some fermentation happening and I was expecting it to be a low alcohol level brew. Is there anyway that I can tell what the original gravity was at this stage? I assume it's too late and will just have to guess. I used a brew enhancer that had 500g of dextrose in it for a 23 litre batch.
If not i'll just have to figure it out by guessing after having a few of them.
If it's an extract recipe it's hard not to hit the predicted OG if you put the correct amount of wort in the fermenter You can put the recipe into a brew app and it will tell you what the OG should have been...most recipes come with this info.
Hopville's Beer Calculus is the free one I'm most familiar with. You can pull out the big guns with things like BeerSmith, but figuring out an OG isn't a great reason to invest in brewing software. Hope this helps!
