Dave, I just tasted both again and have found a significant difference in flavor. I am going to check the gravities one more time because they seem inconsistent with my previous experience.
Overall, the final gravity at 3-weeks was WLP001-1.020, WLP007-1.022. OG 1.070. Since they were a bit high and under-attenuated, I pitched some active SAFALE US-05 into each at 3-weeks and hoped for the best. They dropped a little, but not much and I am going to check the gravities one more time tomorrow.
The WLP001 was really roasty and had a powerful coffee/roasty aroma and flavor....the WLP007 malt/coffee flavor was more muted and dominated more by some the dark fruit/raisin aromas I'd expect from this yeast. I fermented primarily at 67F but raised it 74F for a few days near the end of ferment to try to coax it along to attenuate.
As of today I prefer the WLP001 in my Robust Porter. I am planning to spice the 007 version with some Morita Chipotles and make it Chipotle Porter...http://www.thespicehouse.com/spices/black-and-red-morita-chipotle-chile-peppers
The Moritas look to be fruitier and not as rough as the Mecos but I am going to taste each in a tea tonight to see which I prefer.
