I did an IPA with that yeast. It went from 1.075 to 1.018 in 21 days. I racked to secondary at that time because I was going away for a few weeks. Came back 27 days later, and it was down to 1.012 - 8.4% ABV. I've used 023 several times, but usually with lower ABV brews. Never had a problem with it.
