These are the go-to reference solutions for testing the acid levels in wine. This brand has a 2-year expiration date. The coloration of these references makes it easy to not mix them up.

My only gripe is that it smells very strongly of wintergreen. Your instrument will smell of wintergreen even after you rinse it, meaning something is left coating your sensitive and highly expensive ph meter. This doesn't seem to impact performance however. And other reference materials are not as fairly priced, so its a good buy. My bottles arrived leak-free and were packaged well. I would reccomend this product as long as you can stand the minty-fresh smell that hangs around on your instrument for several days. Atleast it smells fresh i guess!

Some plants need specific pH water to thrive. I use this to balance the number to where I want. ofcourse youll want to be in the lower ranges but they work great. Containers are well built and dont leak. I checked the pH with some strips and the levels were bang on. I thought for the price it was worth it.
