Default alcohol content

just bottled my first batch and everything seems to be going as instructed, but have a question on the alcohol content.

OG was 1.036 when siphoned into secondary and was only about 1.05 when i bottled. According to hydrometer, alcohol content is only about 1.5%. Is that really correct? please tell me that i didn't just make a batch of o'douls!!

thank you!!

Measure OG before you add the yeast, not when transferring. Your number is probably low because the yeast had already consumed some of the sugars. What was your recipe?

Also, a change of 0.031 should be closer to 4% alcohol.

No, the potential alcohol scale on the hydrometer is pretty much meaningless for beer.

(OG - FG) * 131 is a good approximation of alcohol by volume.

(1.036 - 1.005) * 131 = .031 * 131 = 4.06%

OG was 1.036 when you siphoned to secondary? And 1.05 on bottle..... You have some serious errors in your process I believe.

Did you check gravity of the cooled wort, BEFORE pitching the yeast? If so what was it.

When you say you siphoned to secondary at 1.036, fermentation wasn't complete.

Gravity was 1.05 at bottling. This means you increased gravity from racking to Secondary to bottling.

Case in point is, measurements weren't taken at the right time, nor do they sound correctly taken. However, it all comes with time. If tastes good, then drink it.

Oh, didn't catch that your 1.036 was measured when going into secondary... that's not going to be your OG... What's the recipe?

Default alcohol content

recipe: Wheat

1 can of hopped malt extract
1.5-2.0 lbs of unhopped malt extract
1 oz hops (2/3 added while wort was boiling, 1/3 added after heat was turned off)
1 package of top fermenting yeast
1 package of bru-vigor
3/4 cup of corn surgar (for priming)

I got the recipe and instructions (double stage brewing) from Defalcos in Houston and followed them pretty closely. I also have Palmers book and his instrcutions differ slightly, so wasn't really sure what to do there.

being a novice, i went with defalcos and am hoping for the best!

thanks for your help everyone...!

It's not meaningless. You simply need to take the difference between OG and FG values.

See Rick's post above. All of the info you need is there. Your OG appears correct given the recipe.

ok, so the real number to pay attention to is the change in gravity? Man, there's a lot i don't know about this yet, but i'm having a blast learning!
