I made what was to be a 15 gal batch of IIPA, but ended up with 13 gal. This was my first big batch on my new set up. OG 1.090 FG 1.012. I used 2 6 gal glass carboys and 1 7.5 gal bucket. Pitched 2 packs US-05 in each glass fermenter and made a 3/4 gallon starter of WLP001 with Muntons ex light DME. The glass tasted great when I dry hopped today, the bucket did not. The bucket tasted terrible and after a sip it was like it puckered my mouth. When I poured the sample in the sink, I ran some water and it smelled like sulfer. All fermented at a constant 68. The bucket had about 3 gallons in it. I pitched the starter on it. I thought at 1.090 it needed all the starter. Will over pitching cause this? Wish I hadn't lost the 2 oz of dry hops I pitched in before tasting. It sucks!
