Final brew of 2012 - Smoked Porter

Yesterday we capped off a 1 bbl weekend by brewing up 16 gallons of smoked porter. This is the second time we have brewed this beer. The first 15 gallons we made were probably one of my favorite beers of the year.

A few details were changed for this batch. I split up the chocolate malt % using two different chocolate malts. Half came from Crisp Chocolate malt with a 600-700° Lovibond, and the other half with a more standard chocolate malt of 300° Lovibond. Another change up was using US-04 dry English ale yeast rather than US-05 dry American ale yeast. Lastly the bittering hops changed, but the IBUs remained the same.

The recipe uses Briess cherry smoked pale malt as 20% of the grain bill. I really like this percentage on the final product. It is not super powerful, but it is there. It just balances well with the strong dark malts.

The resent issue we have had in the brew house with astringent and tannin flavors seems to be corrected. We brewed an IPA a few weeks back and were extremely cautious about over heating the mash. That beer seems to be fine. We switched back to using our brewtroller system this weekend. We replaced our mid mash thermowell with one that reaches the middle of the mash tun. We used three different temp probe placements (at one time) and found the best to be the one in the mash, followed by one on the mash return. The lest trust worthy was the one on the ball valve. That one has already been removed.

Here is the brew day in pictures.

Brewtroller screen. Nice equalized temperature in the return and middle of the mash and only 3 minutes into the sacch rest!

New sparge arm in action. (I love this thing!)
Popped the arm up and out of the wort to show the spray action. Nice and clear wort!

Sacch rest = break time
