I have been using an EazyTamp with a 30 pound spring. My rationale for the 30 lbs (and a fairly thick base) was that: a) it was the historically recommended norm, b) it more or less compresses the grounds to the maximum compression, and c) thereby eliminates a variable.
However some pundits say I should tamp lighter. My EazyTamp does come with 10, 20 and 30 lb springs. Irrespectively its design ensures a consistent tamp pressure and level tamp, once the leveling flange reaches the top of the basket. You do risk being unlevel before then, namely from the beginning of the tamp until the leveling flange travels down to the rim of the basket.
So, what are your thoughts on tamp pressure? Does it matter? Is a consistent pressure sufficient (ie stay with one tamp pressure, and focus on other parameters such as grind)?
Or should I be tamping with lower or higher pressure? If so, what tamp pressure for what roast type? Or for what bean type? This sounds like another rabbit hole to me 🐇🐇🐇
Anyway I am testing out the 10 lb spring for the heck of it. I am guessing that lighter tamp pressure will require me to grind finer, which may or may not be a good thing …. 🤫🤫
Prefer to not add yet another variable, as I have enough to figure out.
