I decided to lift the lid on my 3 day old fermenter due to lack of blow off activity. Can anyone think of any reason why the smell would be very astringent? Very cutting to the nose while sniffing. Terrible description but I hope you understand.
Are there any signs of foam or bubbles? Have you taken a gracity reading? Do you have a way to post pics?
Without knowing more about your receipe, it will be hard to diagnose... One thing that comes to mind for astringent taste (and thuse maybe nose) is using steeping grains and doing them at to high of a temp.
Infections are usually sour, not astringent, usually
3 day fermented beer can have all different kinds of smells. As long as you sanitized well everything is fine. RDWHAHB as they say. For an example... I recently brewed a hefe with oranges. After a week I opened the fermentor and it literally smelled like feces. Sulphur. A few weeks later its in bottles and probably my best brew yet. Don't sweat the small stuff its fine.
when you inhale a bunch of CO2 like that, it can seem harsh. don't worry about it.
