This was another attempt at a MAC (Mozaic, Amarillo, Citra) IPA. But this time with a bit more beef at 7.1% and hopefully without the faults of previous attempts.
Well, that was the hope.
I bottled some straight from the fermenter and the rest was transferred to a keg and dry hopped. I wasn’t happy with either to be honest.
I think there is a definite oxidation problem going on with heavy dry-hopping. The initial effect is good and gives a strong aroma and juicy character. But these characteristics rapidly fade and are replaced with a rather dull brown appearance.

This is a graph from the Tilt spreadsheet.
The number of samples is low because they are only taken when I placed my phone within a few feet of the fermenter. This I feel is it's biggest limitation. It is possible to use a Raspberry Pi (which I did) but can be quite cumbersome to set up. I like that the data that is captured but not the manner that it is written to a Google spreadsheet. There are definite improvements needed to the Tilt software.
