That's what I was thinking, take it up to my home brew store for some help. If not I'll just use the recipe ABV. Thanks!

Are there alternative ways to test the ABV of your finished beer without having your O.G. reading and without expensive equipment? My hydrometer broke just before I took my O.G. reading, ugh. I'm entering this brew into my first home brew competition and I am required to put the ABV on my entry...
