Im brewing american wheat ale from a kit I bought from MoreBeer, I started my yeast a day in advance, which i figgured out pretty quickly wasnt necessary. Fermintation ,after pitching my yeast, started within a few hours, by the next morning, it had about 3 inches of foam on it an was working furiously. I couldnt get my temp below around 78F here in central texas. I broke my hydrometer so i cant test specific gravty. After only 4 days the foam disappeared,and I cant see any activity. I was wondering if it would be wise to add some finishing sugar to it and start fermentation again, and therefor increade the alcohol content, any feedback on this would be greatly appreciated. Thanks in advance.
 
Before assuming it finished too quickly (can't really happen... if it's done it's done, regardless of how long it took), or assuming it's a stuck fermentation, or you need to add sugar or rouse the yeast, etc. you need to determine the specific gravity. Without that, you're completely flying blind. Can't fix a problem if you don't even know if you have one or not, let alone what the problem is.
 
In 4 days it's most likely that only initial (read vigorous) fermentation is done. It'll now slowly,uneventfully ferment down to FG. Then give it another 3-7 days to clean up & settle out clear before priming & packaging.
 
I think that's probably pretty close to normal. I commonly finish fermentation around the 48 hour mark, give or take a bit, and see little or no activity at 4 days. Sometimes the foam sticks around, sometimes it settles...often depends on the strain I use, at least that I've noticed. The only way to be relatively "sure" is to check your gravity readings. I usually just let it roll for 3-4 weeks, a common practice around here...so I don't even bother checking gravity until I actually go to bottle. I would probably just let it be.

Starting yeast the day before is common, but most of us do it as starters. You probably didn't do anything except increase your yeast at pitching, which might explain the rapid fermentation.
 
If you haven't taken a gravity reading, then how do you know fermentation is finished, and hasn't, let's say, just slowed down? (Which it more than likely has done.) Without a hydrometer, there's NO OTHER way to know.
 
+1 on JMOX14's post

Additionally, 4 days is not too quickly for krausen (the foam) to disappear, the primary, or attenuation, phase when Krausen develops is usually done in 3-4 days.

Your real problem is that 78 degrees is too hot for fermentation, so expect some esters and fusel alcohol flavors to come through on this batch. For your next batch, fashion yourself a swamp cooler (Bucket with water and ice packs) for your fermenter to sit in, put an old tee-shirt over top and a fan blowing on the beer for the first 4-5 days to draw out the heat. That'll get your temps down.

** That is, unless 78 degrees is the actual temp of the beer, and not the ambient air temperature of the room its sitting in. In which case, you'll probably be ok. **
 
78F beer temp is still too high. But giving 3-7 days to clean up fermentation by products after FG is reached will help. It cleans up fusels,etc while it settles out in effect. In actuality,the fusels,cidery flavors,etc are all that's left for the yeasties to eat. They then burp,pee,& settle to the bottom dormant. :D
 
+1 more time.

All of my wheat ales ferment pretty quick, and in my opinion they should be almost a session-strength beer anyway, so I wouldn't add any fermentables. My favorite one was a small kit from NB that has 4# each of base malt and wheat.

I agree that the temps are still too high, I only meant that the beer would still be drinkable. I should have been more clear.
 
That's cool. My first was higher. I listened to the instructions I guess.:drunk: Now I've learned better through experience & here. One stop shop for my beer & pit bbq'ing jones. Concidering making a particular wine again from my days as a new father.
But here's a point to concider. Why is it we like it when they swim,burp,& pee in our wort? Are we a bunch of pervs or what? :D
 
Assuming that everything is ok, would it hurt anything to add sugar to increase the alcohol content? The recipe said it was suppose to be only around 3.8% when finished, i'd like more is all.
 
If you want to add sugar, boil it in water so that everything is sterile.
I don't know if I would mess with it at this point though. You want to set the tone for the beer at the start, not when it's done.

As for early heavy activity, you need to keep in mind that that wort that you oxygenated got a good start on yeast pitched into it.
The reason you need oxygen at the start of the process and not later is the yeast reproduces heavily at the start and they need the oxygen when the do that. It should settle down after the initial blast of growing the number of cells and getting to the work of making beer.
 
Thank you all for the quick responses, I'll prob. just leave it alone for the next couple weeks an see what happens, and hope for the best. I will get me another hydrometer though.
