Brew dog recipe 173 beatnik stout

[sbond10]

Looking thru recipe s on the diy dog book I'm liking the looks of the beatnik milk stout there's a few problems with the actual figures. Windrider helped me out but I thought I best get a broader view too.

I'll put the original numbers on the left then mine on the right

Total into fv 20 l / 23 l
Abv 6.5% / 6.5%
Ibu 35 / 35
Start Sg 1068
Final 1020
Yeast wyeast 1058 / us05

Malt

Pale malt 2130 / 4369
Amber 250/ 513
Flaked oats 250 / 513
Chocolate 380 / 779
Roast barley 130 /267
Carafe special type 3 190 /390
Lactose (end of boil ) 375 /769

Hops

Galena 13.2% 90 mins 12.5g/33.9

Misc

Cacao nibs (end ) 25g/ 29g
Coconut chips (end ) 20g/23g
Coconut chips (fv) 50g/ 58g

Right the problems I see is the lactose running it thru a brewing calculator you get a huge amount. Any suggestions on this amount. Maybe I should decide 375 by 20 then times it by 23
Also I'm planning on roasting the coconut that's both going in the boil and into the fv will this be enough to sterilise it (160 degrees for 10-15mins ) how would you add it to fv jus lob it in and hopefully syphon off the mess.

Any other tips including carb levels would be great

Cheers sean

Yeah, I would think seriously about adding that much Lactose at the end of the boil, and would probably go low at the end of the boil, and add at the bottling stage to taste. (ensuring it is pasteurised before adding)

That's the only thing that jumped out at me without inputting all the totals in to a spreadsheet.

It does seem a lot, you do have quite a high SG, although you don't exactly have many IBUs to counter the sweetness/body

Most recipes I've seen (such as Mackesons clones from when it was a stronger beer) call for about 8% of the total weight of fermentables as lactose. Which is a fair bit less than what you have calculated

If you did want to chuck that much in then I'd probably bump up the bittering, but I've only ever made one milk stout so and not an expert in the slightest

If we take the sensible option which is to divide 375 by 20 you get 18.75 per litre then times it by 23 you get 431.25 so for arguments sake 430 now that seems better to me.

Yep, that sounds about right compared to the BrewDog recipe (I’ve never used Lactose though).
I’m guessing the reason you were getting that higher figure, was because you inputted it into the malt bill and the software assumed you were adding it to the mash?

[sbond10]

Yes I did that but I also put a b in the boil section of the malt bill bit so I thought it would figure it out
