1.087 Milk Stout stuck at 1.035 for 5 days.

[Kunal Vanjare]

Hello, as the title suggests, my milk Stout is stuck after two weeks of fermentation. I have just found out that with lactose, beers may tend to finish higher (FG). I don't know if that is the case over here and don't want to risk having a few bottle bombs.
Edit : current gravity measured with a refractometer and a refractometer calculator!

My recipe if that can help you'll suggest :-
For a 1Gallon Batch,
730g (60%) Pale ale,
90g (7.4%) roasted barley,
68g (5.6%) chocolate dark,
68g (5.6%) crystal 45,
68g (5.6%) munich,
57g (4.7%) flaked barley,
45g (3.7%) dextrin,
90g (7.4%) lactose,

Expected OG 1.071, Actual OG 1.087 (by refractometer)

Pitched around 10grams of dry Us-05.

Planning to increase the temperature from 21c to 22C. Will stirring with a sanitized spoon help?

Was the current gravity measured with the refractometer?

Yes Yes. Forgot to mention that. Used a refractometer calculator as well

Absolutely. Yeast can't eat lactose, so it remains behind in the finished beer, resulting in higher FG. What is your current gravity that is leading you to believe it's stalled?

1.030 is very usual for a FG stout, at least for me.
1.035 FG, which you mention, for five days won't give you bottle bombs and I also don't think it's stuck based on the non-fermentable lactose.
Edit: I don't think you should try and rouse the yeast with a spoon.

Your good. My stout is 1.068 - 70 and FG avg 25 .

Similar question appeared recently elsewhere (link) with some ideas not mentioned here.

I would remeasure the FG with a hydrometer and compare. I'm betting that it's actually lower.

I'll second this. A hydrometer often gives me a different reading than a calculator-corrected refractometer reading.
