breastfeeding and drinking

So for my friends Bachelorette party last night I had one 6 ounce glass of wine, around 8 pm finished it around 10. I got home and pumped around 3 am and dumped it (just because someone told me I should and I was engorged). I'm just paranoid that the milk I pumped at 7 am is safe for my 6 week old. I have a feeling it's fine but I wanted to ask to be sure.
