I've also had good luck with an infrared thermometer ($30, radio shack) since it reads as the water emerges and before it falls through the air.
Squirting, however, doesn't have much to do with temp On my experience. It's bad dose/distribution, and/or excessive brew pressure. Look up the Weiss technique, it helps a ton. best, bmc Sent from my C-Dory On May 13, 2011, at 6:44, Kitt Johnson <[email protected]> wrote: > No Steve, it isn't a very good way to check an absolute temperature (vs. a > relative one that was derived the same way.
