I'm obsessed with Tiger Stripes. No I didn't get a new hat. Nor am I trying to push any fashion boundries. I'm talking about the stripes that mark a well poured espresso. If they appear on your next ristretto you won't even have to taste it to know that it'll be delicious. Yet, on the other hand, if the stripes are absent it doesn't necessarily mean that the shot is bad. I wonder why. But bare with me coffee lovers of Mercury, I might take a little more time re-pouring your double espressos just to get that tiger's stripes to appear. Like I said, I'm obsessed right now.
