I brewed a partial-mash version of this on 7/9. LHBS didn't have Caramel 60, so I subbed Caraamber (30 L), for the following:
Mash (@158 F, nominally):
1# 8 oz Caraamber
1# Marris Otter
6 oz Chocolate Malt
60 min boil:
12 oz light DME (60 m)
.65 oz Fuggles (45 m)
.65 oz Fuggles (15 m)
1# 10 oz light DME (5 m)
I used a no-chill approach. First time trying this, and it enabled me to brew in an evening after work mid-week, which was a huge plus. In this one-batch sample size, I encountered zero problems from no-chill. Very happy. Active period of the ferment was at ~70F and took < 48 hr.
Kegged 9 days after brewing (8 after starting fermentation). Force-carbed and ready within 24 hours (owing to the high serving temperature: my fridge takes a second day to push a beer below 40 F). Turned out to be a really delightful beer.
The one catch, which I have not figured out, is that I ended up 0.010 gravity above target: OG was 1.046 and FG was 1.020. I did have a pretty hard time controlling my mash temperature, so it varied all over the place.
The chocolate-malt flavor really comes through, which I found very entertaining. I mean, there is a component of the palate and the finish that tastes exactly like the raw chocolate malt smells.
Well-received by family. Only downside was that some of the week it was in keg it was blazing hot out, and I would preferred something pale and hoppy to something roasty. The low ABV was a godsend, though.
