I've brewed around 30 extract batches and several partial mashes, all with success. I've never made a truly bad beer. I wanted to try BIAB all grain and used what I thought was a simple American style wheat recipe:
4 lbs white wheat
4 lbs 2-row
1 lb Caramel 10
1oz Amarillo hops
Omega OYL-200 Tropical IPA yeast
I mashed a bit higher than I wanted at 158. My regulator on the propane burner broke half way so I had to move to electric stove top. Ended up mashing for 90 minutes in a cooler while I heated sparge water on the stove. I did a batch sparge with 165 degree water for 15 min. Ended up with about 3 gallons of wort and boiled that for 60 min. I put in .5oz Amarillo at 45 min, and the other .5oz at flameout. Chilled to 70, added 2 gallons of water. The yeast says you can ferment between 70 and 85 so I fermented at 75. I was going for a very tropical wheat with the Amarillo hops and Tropical IPA yeast.
I bottled at 2 weeks, let carb, and just tasted. It's horrible. I can't really describe the taste but there is absolutely no fruity/floral aroma or taste. It's kinda dank maybe? Don't think it has the wet cardboard or vinyl, but it does not taste like beer. I sanitized and brewed like I have for 35 successful previous batches. There is alcohol in it so fermentation definitely happened. Any idea what went wrong?
