Black Sheep Brown ale - Recipe and Tasting

Review and tasting time, (It's morning so, I'm not drinking one now.)

The Recipe is based off this: Riggwelter Brown Ale
Here is my recipe: Black Sheep Yorkshire Brown ale

I bottle conditioned the beer, as I didn't have Keg room. I threw the beer into a recent Case swap, and I find in particular the WY1469 yeast so important to the flavour and ester profile.

Appearance: Very Dark Brown Good clarity, The head retention is an issue on this beer despite the Torrified wheat used duringthe mash.

Aroma: Yeast esters and plenty of chocolate, small amount of roasty-ness, which is a nice touch. i did get a couple of over-carbed bottles, due to some remnants of previous yeasts. Same reports from case-swappers

Flavour: Pretty similar to the aroma, Plenty of Chocolatey sweetness, and Yeast esters. the yeast is so important in this beer, as it drives the esters while remaining very clean along the way. Carbonation is fine, bar a few bottles/gushers from bottle infections.

Mouthfeel: Good mouthfeel, medium body, plenty of maltbackground keeping the nice and juicy, i don't find the beer thin at all. Head retention as I said above is an issue, I'm not really sure why its such a problem.

Overall: Very nice beer, Sessionable at 4.9%abv good mouthfeel, need to fix head retention issues, this is the first beer for awhile, where I've had this problem, no lacing, and the head just drops. I'm assuming theres a protein somewhere that is causing it. when I make this again, I'll probably lighten it up slightly, the gladfields chocolate malt is quite dark, Just back off on the choc malt, and possibly add a touch of Dark Crystal, or Shepherds delight, mainly for some caramel sweetness.
I'll keep the torrified wheatat this stage, it seems to add some mouthfeel, and a nice nuttiness to the beer, which adds complexity and nice flavour.
