You have your marching order. Snap to it.
Madrona Wine Merchants offers free wine tastings featuring 4-5 selections on a theme every Saturday from 2 until the bottles run out and on Sunday we offer a mini-tasting of two wines all day from 11-5. No matter what day you stop by we always have something open to sample.
