Homage, ball park, attempt, in the neighborhood of..... I attempted NSPA, I thought I got it damn close, had a side-by-side tasting with friends and everyone liked my attempt better than the actual, then I tweaked it, and it went the wrong way. But it was still good beer and I might try again in a few batches. It'll never be a perfect match, the water, temperatures, yeast adaptation, batch size effects, other nuances that SN doesn't share. It's all part of the magic of brewing.
