I know you're going to cringe, but ... I can't read my PH strips: the color key is in greens and my sample is pink (red grapes) soo...then I pull out the acid test kit, follow the directions and, drop by drop, swirl, and look for a color change, and there never is one. I'm hoping for the red juice to go to grey but after 3cc's of drops I give up. So at this point I dump in sugar, pitch the yeast and move forward. I am on day 2 right now so may still benefit from advice.
