Yes, that used to be the case I think. The espresso world backed off of that in the last few years. Nowadays the average dose is trending lower. Possibly, half the reason is that a larger dose is more inefficient (i.e. it drops your extraction rate) and the other half is that coffee costs money and for coffee shops that operate at 5-10% margins, 14g doses (standard Italian double espresso) vs 21g (the ‘third wave’ dose up till a few years ago) does make a meaningful difference in whether the store is under water or not. I think it’s settling around 16-18g.
