Noticed that my vial of WLP007 Dry English Ale yeast seemed "chunky". Didnít seem to run as easily in the vial from side to side (bad description, but all I could come up with). When I opened the vial, it seemed to almost have a sourish smell.

Has this vial gone bad? This is my first experience with this strain so Iím in the dark here

Probably wasnít stored properly - they should smell like the medium theyíre suspended in - certainly not sour.

007 is unique in its clumpy flocculating characteristics. Iíve also noticed many fresh yeast slurries smell and even taste tart. Shake the daylights out of it. Cheers

Make a starter. If it doesnít start, then itís a bad vial.

Iím leery of yeast that has low viability. If it takes a long time to start Iíd still dump it. But Iíd dump it into the boil with about 10 minutes left. Dead yeast makes good yeast nutrient.

Thatís exactly what yeast nutrient is made of. And they charge an arm & a leg for it too.

Not sure where youíre buying yeast nutrient, but itís not really that expensive(assuming youíre not talking about DAP)
