Obvious beginner question here, but I need some help and can't find an answer to this question anywhere.

I am pulling doubles through a double spout. The consensus seems to be that a single shot should be 1.5 - 2oz for doubles. My question is, if I am pulling shots through a double spout, does that mean that each cup should have 1.5 - 2 oz (totaling 3 - 4 oz) or that each should have 0.75 - 1 oz (totaling 1.5 - 2 oz)?

Hi Matt…
The quantity of grounds determines whether you are pulling a double or pair of singles, and none of my double baskets would allow me to cram enough grounds in them to pull a pair of doubles.

I moved to a naked portafilter years ago and have no spouts (before that I just unscrewed the double spout and went to a single opening). Double spouts look great in pictures, but are useless since I don't drink singles (I fix triples).

What would be the difference between a double and a pair of singles?

I have a Gaggia New Baby, which I believe has a 14 gram basket (I am NOT using the pressurized basket). I am pulling 1.5 oz into each cup (3 oz total).

If by pair of singles you mean on two runs, then you have two approximate 25 sec extractions.  If you mean a pair of singles from a double pull into two containers via the double spout, then that is just a double pull no matter how you split it.

3 oz of liquid or about 90 ml (90 gms) from 14 gms coffee exceeds what most would call a double.

Great, thanks!

Would there be any significant taste difference between a double into one cup or split into two?

The PF has a central hole and then the spout does the splitting.  They should be the same as it all goes through a central point together.  The article mentioned above is a great read :)
