Hello All,
Just found this forum! I am new to homebrewing and four weeks ago I did my first brew, a vanilla porter. Being a fan of coffee, I did a lot of research on best way to add a coffee taste to it. I did that (cold steep) and this past Saturday we taste tested. Had a few compliments and I thought it was good too. Sunday afternoon, went out to get another glass and the taste had changed. Not sour or rank or anything but almost acidic with stronger coffee flavor. Any idea what may have gone wrong?
Thx in advance
