Funky smell

Just brewed up a hefeweizen, and its been chugging away for the past couple days. Day 2 I had to attach a blow off tube, and now I'm back to the airlock. When the foam was bubbling up out of the tube (through sanitizer), it smelled pretty bad. I don't know how to describe it other than to say it smells like barf. It continues to smell this way coming out of the airlock. I was pretty careful about sanitizing everything with San Star, and the fermentation started up in about 5-6 hours. Should I be concerned about infection?


Here's my recipe:

- 6lbs Bavarian Wheat DME (60/40)
- 1lb Flaked Wheat (Steeped 150 for 30)
- 1 oz. Saaz (60)
- 2 Lemons Zest (pasturized in small pot @ 160 and added to cooling wort)
- Wyeast 3068


The one thing that didn't go according to plan - I wanted to use my glass carboy, because I'm not doing a secondary so I funneled into it. I was afraid of having too little head space for such an active yeast so the final volume was more like 4 gallons rather than five.

Any insight appreciated.

Just so you know, those are referred to as Rhino or Elephant farts. Made famous by Hefe and Apfelwein.

Thanks guys. Puts my mind at ease.

Rhino farts. You learn something new every day.
