I make around 75 gallons of wine every year and decided it was time to invest in a sparger. I got tired of my wines going bad after just a couple years. I looked all over and the only unit I found was over $450. That's just out of reality for me. Then I found one. A small company out of Ohio started making a 2 bottle sparger that does exactly what I needed at a price that makes sense. Evergreen Midwest. Search their site for "sparging-unit" and BAM. There it is. I'm always on the lookout for affordable equipment additions to up my game and this addition changes everything.
