I have a chocolate milk stout that I brewed over 3 weeks ago. It has a pound of lactose in it. This is my first time using lactose. I used a yeast starter and it started fermenting about 4 hours after pitching and was done bubbling by day 3. I let it sit for an additional 3 weeks in the primary and it is still at 1.021. My OG was 1.057. I know that for some beers, up to 1.024 is acceptable. I am not scared because it tastes amazing, but I just want to be sure if I prime it, I am not going to have bottle bombs.

Can lactose (being unfermentable) keep my FG higher than usual? I am going to let it sit another week or two and see what happens, but I am thinking that she is done.

Yup, it'll do that.

Depending on your recipe you could be at final gravity. Lactose will raise your final gravity. Same reading on your hydrometer for three days you should be good to go.

I've got the exact same thing on my chocolate milk stout. I did some research and we are right where we should be.

For the fun of saying what everyone else is saying:

Yes Lactose will cause a higher than normal FG. I know my milk stout normally finishes around there and It is one of my absolute favorites.

mine is around 1.022 and seems to be finished. after looking around it seems to be pretty normal

My milk stouts usually finish between 1.020 and 1.024, so you're done.

Hearing this makes me feel better about it then. I only questioned it because in my BeerTools it said that I should be at 1.014 for FG based on my recipe, but my OG came out 3 points higher than BTP said too.

Thanks guys...Can't wait to try the finished product.

Lactose is 100% unfermentable, and has a PPG of about 36. That means a pound in 5 gallons will raise your OG and FG by about 7 points. I would imagine that Beertools is using it to calculate the OG, but then just calculates the FG as a percentage of the OG based on the yeast you choose (% Apparent attenuation), without taking the ingredients into account.

Same issue here. 12 days in the primary and 3rd reading at 1.022 with an O.G. of 1.050 however I only used 8oz of lactose. I'm in no rush so i'm going to let it ride a little longer but I did notice all airlock activity has completely stopped as of last night. I know it's no way to judge but it sure is quiet even after a nice sloshing around in the bucket earlier. I'm sitting right at 64 - 66 degrees constantly which seems about right to me. Any thoughts? I kind of was hoping to get this thing racked over and bottled in time for December-holiday-fiasco-dinner and such.
