ok, on the hold. Was only my second partial mash. Feel much more confident now, with hold a consistent mash temp and getting a good boil.
Next time I would up the pilsner, and reduce the DME. Maybe up the Special B and Caramunich to 150g or 200g each. But the Dark candi syrup - tastes real nice! I didn't add a whirlfloc tablet. That is something I now do at the end of the boil, so it was a bit murky. I hope that it would be clearer next time from this, and maybe some fining agent. I needed to up my saaz amount too.
So, there are my improvements for next time. Hope that gets you on a good track.
