Uhm, while that sounds good, what about it makes that 'proper' and , say, a 50 ml doppio pulled in 25 seconds from 14g 'not proper'? The only standards that I know about are the INEI, and the WBC. Neither of which describe that as a 'proper' double. OTOH, the WBC doesn't rule it out, either. Just curious as what high water mark you're using, and under what bridge? ; >

I tend to refer to it as the 'Golden Rule of Thumb'. It is a perfect place for a newbie to start at, as you can (almost) reliably depend on that recipe and following the Four M's to get you something better than what you'll find at most chain stores and lots of independents. From there, experiment and adventure, but it's a great place to start out and a great place to do some diagnostics if you're trying to suss out a problem via the interwebs or the telephone.
