Title: Imperial Oatmeal Chocolate honey biscuit Stout
Post by: JMK8 on March 29, 2019, 10:06:36 AM
Morning all,  I am brewing an imperial oatmeal chocolate honey biscuit stout at the weekend but I am not sure what yeast to use.  This is an experimental brew so I am only doing a 5litre batch. Rip it apart all you want!  I know there is a lot in the grain bill.

It will be a 90 min boil.  OG is 1.106  FG is 1.026  ABV is 10.2  IBU is 53.9   Eff=63%

1.8kg Maris Otter Pale (66%)
150g Malted Naked Oats (5%)
150g Flaked oats (5%)
180g Chocolate (7%)
100g Honey Malt (4%)
150g Biscuit Malt (5%)
100g Roasted Barley (4%)
100g Crystal 60L (3%)

10g Nugget @ 90 mins
12g East Kent Golding @15 mins

Yeast I have no idea.  Dont want to spend alot of money on liquid irish ale yeast as it is only a 5L batch.  Possibly nottingham ale, S-04, US-05 or  M15 Empire Ale Mangrove Jacks??

Going to add cacao nibs @ 10mins in boil and cacao nibs and 1/2 a vanilla pod soaked in irish whiskey for 7-10 days after fermentation.

Any ideas on the yeast

Not sure your OG is correct.

I have used S-04 for a number of years now and brewed many stouts. Works well for me.

With an OG of 1.106, I'd use more than 1 packet of yeast.

The yeast pitch calculators I have used have said 1 packet should be enough?  Do you think I will need two for a 5 litre batch?

One pack would be enough.

Perhaps one would be enough for such a small batch.

More like a porter than a stout. The 4% roast will be drowned by all that sweetness you have in the rest of the malts.

Fair point. Would you suggest maybe upping the roast to around 8%?

Depends on what you want this to taste of. More roast will make it more of a stout. How sweet do you think it will be.

1.026 fg is gonna be very sweet.
There is also chocolate malt in the recipe that will go towards the roasty. For a normal stout id aim for about 10% roasted but for imperial I'd well up that.
