Bobek Pale Ale
Posted: Sat Sep 12, 2009 1:27 pm
Just finished brewing my Bobek Pale Ale. This beer has a few uncertainties with it though . . . the mashtun let through quite a few small grain particles (so I may end up with tannin beer), the vacuum seal on the hops had failed at some point while they were in the freezer (so the estimated bitterness may be off the mark) and the sparging went a bit quicker than planned, so my efficiency is down!
So, the recipe was (given that I've got only low colour MO in on the grain front at the moment):
4011g LC MO (mashed at 69 deg C)
42g Bobek 5.2% for 60 minutes
42g Bobek 5.2% for 15 minutes (+ 1 No. protofloc tablet)
20g Bobek 5.2% steeped
Danstar Nottingham yeast.
Calculated OG: 1042
Actual OG: 1040
Estimated bitterness: 35 IBUs
The mash went very well, the £10 argos sleeping bag really retained the heat well - temperature dropped less than 2 degrees over the hour! Quite pleased with that. Less pleased, however, with the grain particles I mentioned that managed to get through. Touchwood it hasn't had a big impact on the beer. Sparging was super quick, although that probably didn't help matters.
I was concerned about how murky the wort was looking as I was cooling, but after I gave it some vigerous stirring it seems to coagulate the proteins and it dropped crystal clear.
Bizarre.
Given that I didn't start until after 9 this morning, I am pretty pleased with the progress! The FV is tucked up now.
Chosen Nottingham has I want this beer drinkable in 2 weeks time really. So 5 days ferment, then rack into the barrel for 9 days. Hopefully that'll be sufficient!
