I don't think it wipes out progress. Progress is cumulative. But it is a slip and it makes a difference in that you are still in the grip of your addiction. Notice how easy it was to cave into the "voice" that said drink. It happens at three days, three weeks, three months.
If you need to take something from your "sip" take this--be vigilant in your recovery. Your alcoholism isn't taking any days off. Your sobriety can't either.
