Was brewing for years then took off about 7 yrs and recently got back into it. Had very same issue and lhbs had me add more malt. Will back sure it ferments down but great post. Enough for me to sign up as a member. I like proactive people.

I ran into this problem last night while brewing my first Porter. It was my fifth brew, and first time i did not hit the correct range for OG. Recipe called for OG in the neighborhood of 1.050 and I got my initial reading of 1.072. It was extract with top off. I mixed it around for only like 1 minute then took my initial reading. I then aerated with O2 and took another reading. That was 1.068.

Its not a big deal because I am going to drink it anyways. My only real question is how will i know what the alcohol content will be? Should I just assume the OG is around 1.050? Or should I drink 4-6 bottles when it is ready and try to judge how big my headache is the next day?

Ifit's extract with grain, and your volume is correct, the ACTUAL og is what it should be. It can't be anything other with extracts. You are not converting anything.

It's not impossible at all. I've done three kits so far and every one had an OG that was right on the money.

I pretty much always assume that no matter what my OG reading is, its pretty damn close to whatever the recipe called for. From my understanding, its pretty hard to miss the OG by much with an extract recipe.

I've been moving towards full boils (maxing out with 5 gallons to start the boil, then topping off with about a gallon of spring water to make up for the loss to steeping grains and boil-off), and I've been finding it easiest to just measure the OG pre-topoff, and adjust the reading to my dilution factor.

Thanks for the responses. I now understand that it is pretty hard to mess up the extract numbers because there is no conversion, as Revvy stated. And full boil is one of the goals, but getting a fermentation chamber setup is first. (hopefully this weekend).

That's also been my experience for years.
I'd be real interested to watch exactly what people are doing that make the reading so far off.
Youtube maybe?

I've been stirring (as many as 200 stirs) and still get a slightly high reading - about .003 - .004 off. I could stir longer, but I don't see any real advantage. Is there anything wrong with just using the kit specified gravity? I've already aerated, so I was thinking of backing off to 100 stirs and accepting an even greater discrepancy. The sooner the fermenter is covered and sealed, the better I like it.

There's nothing wrong at all with just using the kit gravity for an extract batch. Fermentation will mix water and wort together just fine.
