Well, the La Peppina I just received came with a single and double basket, and what with all this seeming renewed interest on the forums about singles, I've started to try it out. I didn't have a single basket on my previous rig.

I can't say that I've settled on a dose yet for the La Peppina single basket, but it's fun to try. I think I like pulling singles because it gets me more opportunities to practice with the new machine without pulling for the sink.

With the size of the Peppina a single may be more like 3/4oz.

I'm finishing most of my self-training sessions with the La Peppina with a single. I went through a patch of trying to pull exclusively singles with about a weeks worth of sink shots and went back to pulling doubles, but after I gave up trying so hard and re-read some old forum posts I found that singles on my La Peppina like a very different pull then doubles. For the single, I'll pull the lever down, raise it up about 1/3, back down, and then guide the lever back up until I feel resistance. This minimizes the pre-infusion on my 7 g singles and yet I get darker spots of crema under the spouts with the single.

I'm still playing with the dosing on my double basket and dialing in temperature, I'll be a week away from my espresso and may pick up some locally roasted beans upon my return to practice on (Bigfoot, Ritual, or Ecco) instead of my homeroast. My last session I was pulling 16 g doubles of homeroasted New Classic Espresso at 203, 204, and 205 F in the kettle, 203 tasted best today.

While I prefer doubles, I'm finding that I like the taste of the single too, especially after I've had several doubles already.

I almost ALWAYS pull doubles...infrequently triples...and almost NEVER singles. If there is no one around with which to share the double, I drink them both...sometimes as a double cino or as a straight shot chased by a cino...sometimes as a double straight shot. YUM!
