Default Finishing Gravity pretty low.

Im doing a williams brewery extract kit. its my 3rd batch. the first two turned out ok, but nothing amazing. finally i decided to try something stong, which is typically the kind of beer i like. i went with a west coast style imperial ipa.

i did not check my starting gravity, my first mistake.

the beer spent 9 days in the primary, then an additional 18 in the secondary. it was stored in a 68-73 degree room.

today i took the first hydrometer reading. and its at 1.032, while the directions for the kit are telling me to expect 1.042.

my questions are: what could i have done to cause this? how, and in what way, will it effect the beer? and what general tips do you have to counter act this kind of thing in the future?

Thanks in advanced.


Edit: Thought i would update: everything turned out great, im not sure if this is how the beer is supposed to taste, but it tastes as good as something i'd pick up in the store. ive had the chance to have a few and i couldn't be happier with it.

finishing gravity of 1.032 is not low, its very high... are you sure the FG from the kit expected 1.042, thats very high

yes, im sure that they called for 1.042 i just triple checked, just to make sure. i have the paper right here.

i also thought it sounded extremely high (most beers ive tried previously were 1.018-.022

although i have a Belgian quad that is saying 1.028)

but this does say 1.042.

Highly unlikely that number is right. What was the OG?

he forgot to take the OG reading, but if it is that high now, are you sure fermentation even occurred? is there lots of gunk around the edges?

yeah, it bubbled like crazy for 4-5 days. and grew a pretty big amount of foam after going into the secondary after a day or so.

and yes, i forgot to take an OG

the best i can do is this: "Makes 5 gallons of strong ale with a starting gravity of at least 1.088"

its not the starting gravity that i had, but it is what i *should* have had. had i checked.

Normal FG for an American IPA is in the 1.010 to 1.018 range. Normal OG is 1.055 to 1.075 or so.

I dunno what kind of weird IPA recipe you've been given if it actually says to expect a FG in the 1.040's. Many ales aim for an OG in the 1.040's. All I can say is that a lower FG corresponds to a higher alcohol content. So if your yeast is crapping out at 1.032 and the recipe says it's going to crap out at 1.042, you've only made stronger beer.

Of course, without knowing your OG we can't really say too much. What kind of yeast did you use?

i've never heard of a beer finishing at 1.040 -- not even a barleywine. It would probably be damn near undrinkable, like syrup.
