Codename: Chinatu Take 2 APA / NZPA

IMG_0010Another brew day done and another batch in the fermenting chamber.

If you watched my Home Brew Wednesday this week, you will see I wasn’t happy with my Chinatu recipe. Whilst it was a lovely beer, it didn’t have the level of flavour and aroma that I was hoping for, so this week we brewed the take 2 batch with some changes to account for the grains I had in stock and also to add 50% more late hops and this time I’ll be dry hopping for a week after the first week of fermentation is done.  I’m looking forward to seeing how much of a difference that makes.

I am starting to get much better at making notes during the brew day, thanks to one of Tiny from Off Tap brewings tips about taking notes.

I noticed that the mash temp had dropped a bit after it had settled down so I had to add another litre of boiling water to get back up to my mash temp.
Also saw that I was just about bang on the pre-boil gravity at 1.044 when the recipe estimate was for 1.043. I was quite surprised to see that my post boil gravity was a bit low at 1.043, but that may be due to my refractometer and really I should have got the hydrometer out before I pitched, but I’m guessing that I did hit the estimated 1.048 as I know my refractometer does some funny things with cool wort.

Anyway, here is the Chinatu II recipe and I’ll update this post with notes and a taste test when the beer is ready.
