I'm planning to do an APA with only columbus hops. I've heard that columbus' aroma is piney, it is also described as pungent (what does that mean?).
How much should I add for dry hopping 9.5 gallons of beer? I plan on using 0.7 oz at 60' and 0.7 at 15'. Then dry hop it for about 2 weeks.
A friend of mine warned me to not use columbus because it's too bitter, maybe he used too much. According to beersmith these additions will result in less than 30 IBUS, which sound very reasonable for me.
