A couple of months ago, I bought a Milwaukee MW101 pH meter.
One thing I wasn't expecting is that it takes about 2-3 minutes to get an accurate reading. When I first insert the probe, the initial reading is usually around 7 or 8, and then it slowly starts going down until it eventually settles at the final reading. I have found that gently stirring the probe in the sample speeds the process up a bit and actually seems necessary to get an accurate reading (as confirmed with testing solutions).
I've never heard anyone mention this before. Is it normal or do I have a bad probe (it's only about 6 months old, and I store it in the recommended storage solution)?
I'm doing an Ginseng American Amber today for my neighbors. I added to the sparge water 26 ounces of ginseng tea I made by simmering 2.25 oz of chopped American ginseng and 1.25 oz of whole spirit ginseng for an hour.
If it doesn't have enough ginseng flavor, I may consider dry-hopping with ginseng or making a very concentrated tea and adding it to the keg.
Not bad - Kai's spreasheet predicted a pH of 5.6. Colorphast strip read 5.3 (Kai's experiment showed these strips tend to read 0.3 too low, so if I was only using the strips I would have called it 5.6).
Using an old yeast tube to store the probe has also been working out well.
