Before thermometers were invented, winemakers and brewers would dip a thumb or finger into the liquid to determine the ideal temperature, either too hot or too cold, for adding yeast. That is supposedly where we get the phrase "rule of thumb."
Every since I got a new camera for my 30th (my beautiful Canon T1i Rebel), I definitely think my photos have been improving. I was therefore quite happy to see that A.T. Richardson Wines are using my photo after my feature on Chockstone Shiraz. This year A.T. Richardson, next year National Geographic!
