I brewed yesterday, when I opened up the smackpack I noticed a different smell to it than I've smelled in the past, almost like burnt popcorn. I admit I've been sick the past week with sinus problems so the sniffer probably ain't in the best shape. Its fermenting away just like normal and the smell form the airlock smells like hops and fermenting beer.
Just wondering if anyone has ever opened up a bad pack of wyeast? The dates on the pack were from March. It may have gotten a little warm about 3 weeks ago when we moved and took it out of the cooler and didn't place it in the fridge for a couple of hours. It did swell a touch then but not much.
