You can try a quick water-rinse first and fill while it's still wet. A dry, brushed SS surface does create a lot of spots for bubbles to nucleate (similar to micro-scratches in a champagne flute) but the residual water smooths things out.
You could also check out Stanley's GO growler with a "ceramic" internal coating; easier to clean, less residuals, and smoother surface for smoother fills.
