Sour mix 1 starter?

[Sayers]

Going to make my first sour and I have 1 vial of white labs sour mix 1. The batch will be a 9gal lambic. White labs says you don't need a starter (for 5gal I assume) but thinking
I probably should. Your thoughs?

It's a blend of yeasts and bacteria. If you make a starter, the relative proportions of yeast and bacteria will change, as will the character of the final beer. If possible, pick up another vial or two. If not, pitch it directly and be prepared for a really long lag time.

Definitely do not make a starter, but you may want to pitch more than one vial of that yeast strain. What is the intended OG of the beer? Lambics are normally around 1.050 OG, so I think probably 2 fresh vials would be a reasonable pitch rate for 9 G.
