Jon,
Excuse my ignorance but what is "pulling a triple"?


Yeah so it's like a white elephant. There's really no reason besides experimenting to pull them; kind of like single shots. I may get crap on this but pulling singles or triples imho is for fun with the very occasional better shot unless you roast the same beans all the time and can mess around. Basically the same water to grind ratio. I hate to give volume/ground/shot timing figures because espresso is a fickle beast and shot timings, volumes, dosing can literally vary with humidity, age of beans, the day of the month, if your dog crapped on the right or left side of the yard. Attached is a piss poor pic of three baskets on potentially the dirtiest coffee bar setup. Sickness in the family so things are a mess. Ugh this forum host drives me nuts. Here's an external link to the pic - promise it's not a windows ransomeware atttempt. Pic size is too large to ul and I can't get the link to be clickable so copypasta away. EDIT - I think the more intelligent mods fixed the link unless David Blaine got involved. EDIT EDIT - Jack "the Blaine" got to this while I was typing. Thanks for the near instant fix!

I had to use the full link to get it to work. I think the system does not like the shortened links.

You have to use a command that generates a url that points directly to the image file. Some sites will not allow this because of traffic issues. I know photobucket works.

I went to your photo on the google site and did a sinpping tool capture and loaded it as a JPG.

Thanks for the explanation. Being new to espresso, I was not aware there was a basket made to hold the triple shot charge of 20-21 gm. I've definitely noticed what you say about how finicky conditions can be in getting the right double pull timing. For me, probably the biggest factor has seemed to be charge weight, but I will now definitely start noting which side of the yard the dogs crap on too!
So many beans; so little time....

Jon, I have been using 20 gram in my what I thought was a double basket for my Gaggia Baby Semi. Am I really doing a triple? How much max does a double basket hold? My basket (what I thought was a double) can hold 21 grams compressed.

"The size can be a single, double, or triple, using a proportional amount of ground coffee, roughly 7, 14, and 21 grams; correspondingly sized filter baskets are used.
The Italian multiplier term doppio is often used for a double, with solo and triplo being more rarely used for singles and triples"

If you can squeeze the grams in a double you're technically pulling a triple but headspace from grounds to filter screen can also have a major impact so triple baskets are typically a little taller and the apex of the bottom of the basket curve is tighter so more coffee can get crammed in there. Opposite for singles. The basket is shorter but if you look at the bottom the perforations are maybe 50%ish more restricted and the curve is major.

I hate to really give any specific volume/dosage/timing "facts" just because espresso is a fickle beast. You can have a traditional dose pull all different ways. Machines pull different as well. My Gaggia pulled totally different than the VBM.

My feeling is forget about the definitions, figure out what tastes best for you and roll with it.

Jon, I am relatively new at the espresso thing. How tight are you supposed to put the portafilter on? Till it will not budge any longer, or looser?

It should be cranked in tight but don't go all Schwarzenegger on it. I've also found as the gaskets in the brew head get older and harden the portafilter tends to back off a few degrees once the brew pressure hits. Basically as long as you don't have water leaking from the top of the basket and you didn't break anything you're good. IMHO there's a pretty lenient torque range.
