Small batch of GH Yorkshire Bitter. Modified according to what I had in stock. Hoping to buy a bigger kettle in the new year. I won't miss the will it, won't it, boil over moment, that comes from pushing the capacity of my current setup!

Hi @Hazelwood Brewery

Hi HB,
I see you are experimenting with using hops in the mash.
Being a typically bucket chemist, I thought I would chuck in 10g Citra to the 60 min mash at 66°C, followed by a 30 min 78°C mashout.
The aroma was rather good.
As they were all mixed with the Grain and removed with it, they weren't boiled.
I think I saw you say these don't add any boil bittering, so they do not need calculating in to the total IBU sum.
Did I get that right?

FYI Charles Faram have a technical discussion paper on Thiols, if you haven't already seen it.
I only noticed it whilst doing a hop variety data sheet search, so haven't read it.
But I will.
Regards,
Robin.
Hi Robin. Sorry I managed to miss this post somehow. Mash hopping does add bitterness but assuming you’re using leaf hops that get removed with the grain it’s just 10% of the bitterness you’d get from boiling those hops for the same amount of time.

So, assuming 12% AA for your hops you would normally get about 16 IBUs from boiling 10g (and assuming a 23 litre batch) so this would mean less than 2 IBUs from mash hopping.

If you used pellet hops it would be significantly more because pellet hops disintegrate and do make it into the boil.

Edit: I just checked my notifications and actually didn’t receive a notification which is strange. @Chippy_Tea are you aware of this as an issue / able to say what happened?

Hi HB,
Thanks for the extra info.
As for Post notifications, I thought It was me who had done something wrong.
I didn't recieve any posting alerts for about 36 hours, email or on the forum red number superscript on the notification Bell.

Question: How do you know what the exact point that wort will boil at?

Answer: It will boil at the exact point you look away to do something else!

Exactly what happened to my porridge yesterday... Was a good reminder before today, When I it was far more Important to pay attention!
 
22 litres of Vienna Lager
4000g Vienna malt
650g Munich light
125g Melanoidin
70g Carafa 3
Northern Brewer
Tettnang
First Gold
CML Hell @ 16C
 
Just mashed in for a batch of Stout, I am using the Graham Wheeler Top Dog recipe but scaling to 9L and replacing the Challenger shops with Bullion which I am sure aI remember reading somewhere are supposed to be good in Stouts so thought I would give them a go.
 
21 litres of Exmoor Gold
5000g Maris Otter
40g Challenger @60m
20g EKG @15m
1 Protofloc @15m
20g EKG whirlpool 80C for 20m
Gervin yeast @18C
I made 19 litres but added 2 litres of water to achieve an OG 1052.
 
Bottled two-thirds of my Grey Sheep III today. I'm keeping one demi-john back, and am going to leave it for another another week or so after normal bottling time, to see if that makes any difference.

Also bottled the last batch of parsnip for the year.
 
I made a batch of that Exmoor Gold some time back, and to be honest the result was pretty meh. I have never been able to produce anything really successful in the English pale ale/golden ale style, for some reason. Everybody seems to love it, so obviously it's me that's the problem, not the recipe. I think I shall largely stick to stouts and bitters in 2022.

The thing is to keep it simple I.e.
1 malt
1 or 2 Hops
1 Protofloc or Irish moss.
Proven yeast I use Midland or Gervin.
Cold crash before packaging. Has to be crystal clear at that stage.
 
I used the same recipe I think. I think you are right, Cheshire, it's probably the cold-crashing (or, rather, lack of it) that's letting me down.
 
Was expecting to call it a day for 2021, but noticed parsnips were reduced to 19 p per packet in Lidl today... :D
