This is my second go at brewing Vienna Lager but this time it isn’t just practice – this ones going to NHC assuming it is one of my better beers at the time of submission. some small (ish 🙂 changes from my last Vienna. I moved from Weyerman to Best Malz for my base malts (Pilsner, Vienna, Munich). I also added a bit of color using Briess Midnight Wheat. Lastly I used the German Lager strain from White Labs.
I did a 2.5L starter of 2 yeast vials that were under 1 month old. Starter went well except stir plate is kicking the bucket.
I went to a different homebrew shop which is closer since they carry the Best Malz but their crush was a bit coarse. My own fault since I set the crush. Boooo me. Efficiency were spot on though it appeared to not make any difference. That said, my wort was a bit hazier than I’m used to so I wonder if there was some left over starch in there. We’ll see.
SG was right on which may well be a first. I ended up adding 1 L of filtered water to boil to hit my end of boil gravity on the nose.
I used the same cooling technique again (kill whirlpool but leave cooling water on when I let it sit for 20 mins before going to fermenter) and it worked perfectly. I cooled to 47 and after 20 minutes of settling time it was down to 45 and up to 48.5 by the time I got it in the fermenter, oxygenated and pitched.
