Default wondering if og is WAY too low

i'm wondering if this beer will turn out well.. i suppose time will tell, but i wanted to see what everyone else's thoughts were.

i made a 5lb batch of cream ale based on a recipe on here by someone else.

it was

8lbs of 2 row
2lbs of flaked corn
.5 lb of instant rice

i tried to shoot for 152 deg mash but i think i was under by about 2 degrees which may be part of my problem

my pre-boil gravity was 1.02
and my post boil gravity was 1.032 @78 deg

so you think it will turn out ok? i imagine it will be VERY low in abv

You may have had some issues while mashing. Did you do an iodine test to see if starch conversion was complete? The beer will still turn out fine, but will have a lower ABV and maybe a sweeter taste. Since your brewing a cream ale, that's not necessarily a bad thing.

No i dont have the stuff to do the iodine test. But after that batch. I may have to pick that stuff up

Just pick up a bottle of iodine from Walmart or any kind of grocery store/pharmacy. Iodine turns the starch in your mash a blackish color so if the iodine stays the same reddish rust color you know starch conversion is complete. Just make sure you do this test on a white colored surface away from the sweet wort...I can't imagine iodine adding good flavors to beer.

If you're using that much iodine to test that it's a safety concern then you're doing it wrong. Iodine isn't poisonous unless it's in huge concentrations. It's just fine to use in low quantities, which is why your LHBS likely sells Iodophor...an iodine solution that you mix to a 12-15ppm solution with water to sanitize brewing equipment.

That's not to say that I wouldn't do my conversion test away from my open mash tun, but unless you accidentally dump a whole bottle in the mash you'd likely be OK (depending on the size of the bottle...).

Yeah, it'd take a lot of iodine to be poisonous. Considering folks use it to treat drinking water (tastes nasty, but it sure as hell beats getting disentery), gonna go with not a poison under normal circumstances.

As for the OP - that sounds very similar to a recipe I just did... Except I used 7lbs of base malt and a full 11oz box of minute rice. And I wound up on the other end of the scale; I was expecting around 1.040-ish, and hit nearly 1.050...

Now... What OG were you expecting? Doing a temp correction, and assuming your hydrometer is calibrated for 60F like most are, that 1.032 translates to 1.034... So yes, you're a bit on the low side - if your yeast (what yeast are you using, BTW?) attenuates around 70%, you're looking at about a 3% ABV... Should be a pretty friendly summertime beer, if nothing else.

I was mistaken. I used 6 lbs of two row not 8. Sorry

What program are you using? If its not the mash you could of had some bad yeast, but my experience has never involved bad yeast. Is it liquid or dry yeast? I've always hit final gravity marks with liquid yeast but dry yeast has been fickle at times. Also, it could have to do with temp at fermentation and time you had it fermenting.
