Here's where I got mine. Not sure how the price compares since it's the only time I've bought them, but it was good enough for me:

Thanks. That's actually where I got mine from last, I was confused.

You might be happier with the pH strips from Precision Labs as they have smaller ranges.  http://preclaboratories.com/?taxonomy=product_categories&term=beer-and-wine.  I've never used the colorpHast so I can't say for sure.

Where do you buy these? No ordering info on the site.

I would like to have test strips for lower pH (sour beer, sanitizer check)

LHBS carries those. The color change is so faint I can't tell jack squat. The colorpHast is bad enough but accurate enough against my meter. Just use the strips as back up I I tend to go through probes.

I get mine at the LBHS.  I use the wine strip specifically for sour beer and for StarSan checking.

I won't deny that the changes are subtle around 5.6.

I have a hard time telling the difference between 4.8 and 5.2! Looked mostly white with the faintest shade of yellow to me.

I'm with you, I've tried them and I have a hard time telling the differences

Man, I hope that is not true; I'd have to start using my meter again.

Keith can you clarify - were they discontinued by the manufacturer or just by your vendor?

The link said they were discontinued. But then I realized that wasn't the place I used to get them from. Surely the vendor is simply not carrying them any more. Didn't mean to imply they were discontinued my manufacturer.

I don't trust the strips these days... I find that they're in the ballpark for light colored beers after Kai's correction of .3, but they still underestimated pH for dark beers.  This leads to the worst possible "remedy", adding extra alkalinity.  Plus, estimates aren't that helpful.  I either want an accurate reading for a new recipe to make adjustments or I'm going to let it ride.
Please do not reply if your an evil alien!
