That’s not a hypothetical question. I have yet to see a mezcal boilermaker, I’m sure it’s been done. But a local San Francisco brewer recently caught my eye because she really is adding mezcal to her beer, but before it gets into the keg. Meet Regan Long master brewer of Local Brewing tucked behind the San Francisco Tennis Center on Bluxome Street in SOMA. She has been producing a mezcal beer called Mezcal Red for three years now, the real question is why it took so long for me to notice. It’s now a staple brew for Local in the holiday season so stop by soon to get a taste before it's gone.
