Last year I made a biab IPA in my aluminum brewpot. I posted some questions after drinking some last year cause it was quite dark and tasted very malty/bitter. I kinda liked the color. It was very clear and a nice deep red hue.
I made the same recipe a few weeks ago but normal mash in my cooler,etc,etc. This batch is way lighter in color and not any where near the same flavor or maltyness.
I’m wondering if perhaps mashing in aluminum pot via biab may have pulled color and or some off flavors from the black stuff on the inside of the pot. Anyone have a similar experience or have a theory?
Grain bill was the same for both batches, same yeast, mostly same hops but not identical.
