There’s a brand on here that will have much less variation than most brands, because they measure all incoming product for accuracy, and blend the final product by weight, not volume. Then they also test the final product to ensure everything is within a tight tolerance.
This ensures bottle to bottle, batch to batch variation is likely less than the measurement accuracy of the testing equipment. They’re certainly not the only place to take this level of care, but they hang their hat on delivering exactly what they promise. To me, trust is worth the couple extra bucks it costs for their products.
