I'm starting to get the impression that my two double shots every other day (I drink tea on off days) is real minimal, how many shots do you have a day? Once upon a time I downed many more a day but doubt I could survive that today.

Many days it's just one double in a day.
Other days, it's a lot more (today was 4 doubles, and then cupped 12 coffees).

But espresso and coffee in general can and I'd argue should be a culinary experience not a pharmaceutical experience and as such it's quality, not quantity that matters.

Two doubles in the morning - an occasional single at night.

weekdays - 1 triple basket double @ 7am, 1 double basket double @ 1pm
weekends - 3 triples basket doubles between 8 and 3.

emergency doses can happen between 4 to 7pm if circumstances dictate.

I try to keep it down around 4 doubles a day. It does get up as high as 6 or 7 sometimes, though. Needless to say, I am a pretty twitchy guy to be around.

See How many espressos do you prepare each day? for previous discussion. For me, it's about available time. Usually I'll drink 2-3 espressos. If I have lots of time, I'll prepare 4 "bracketed" shots (e.g., changing dose or temperature at each step), tasting two and drinking two.

Having missed the previous poll...

At least 3 doubles every morning, one before breakfast, 2 after.
1 double decaf after dinner.
On weekends 2 additional double after lunch and whenever required.

Sometime the doubles will be replaced by twice the quantity of singles. Whenever I really want to sit and enjoy the drink I will do singles. Also, whenever I am trying to taste-experiment or do hardware or process modification I will do singles.

Contrary to a lot of people on this site. I find that making singles is easier and more reapeatable for me. I do double to go faster in the morning...

I typically have a double cappuccino every morning.

Around 6 singles a day
