Specific gravity of batch didn't budge

[vash1012]

I brewed an english brown ale about 1 week ago. I used a liquid yeast, popped the inner bag as usual, but the bag did not swell very much in the 4-5 hours it took to brew. I did not think much of it since I could hear bubbling on the inside of the bag. Well, a week later, I pulled the lid of my brew to see if the yeast took since I never saw any bubbling the airlock. The OG of 1.052 hadn't budge an inch, theres a spot of mold on the top and on the lid as well, and it smells like sharp beef stock.
I am assuming the yeast did not take and possible some wild yeast/bacteria took hold instead. Should I dump or repitch another pack of yeast?

I'm not expert, but ya it sounds like your yeast died somehow. Of course you could pitch another packet and probably make beer. However the lack of CO2 and alcohol has made your beer prone to infection, hence the mold. If you're not going to brew anything else in the bucket in the next two weeks, run to a local shop and get some yeast. Columbia, SC there is Bet-Mar on St. Andrews road just off of 26. Might as well make something out of the $25 you spent. Just my 2c.

Don't give up hope, if you have the bottles to spare, let the thing sit for 6 or 8 months even if it goes in a little sour. That's what I've heard. If it's terrible with tons of infection in two weeks then I'd probably pitch it.

I am sure an expert will chime in...so wait for thier advice. Its possible the "Mold" is the dead yeast....so you may not have anything to worry about...If its been 5 days...you will probably have to repitch IMO...

beef stock seems like a rather odd and discouraging smell (but can't say from experience). I doubt wild yeast took over since there was no change in OG, but bacterial infection/mold is a whole other story (but that can be from any portion of the brewing).

I'd grab some traditional dry yeast (safale or nottingham) to save a little $, ferment it out and call it an experiment/learning experience.

I'm curious to see what more experienced brewers will say!

Thanks for the replies guys! Nice to see another columbian on here!

What temperature was the wort when you pitched the yeast?
