So I just bottled my first beer, and had a little left over that didn’t fill a bottle. I gave it a taste and um..... it tasted quite bitter. Kinda harsh like a shot of vodka. I let it ferment for 3 weeks. Did I do something wrong? Or is that normal for it before bottle conditioning? It smells like a decent beer. Does taste a bit like a decent beer behind that harsh bitter and stringent kick.
