Last weekend we headed to Galt from Alameda for the Winter Bird Festival. We stopped at the Delta Foundation's store, the Delta Farmer's Market, near (I think) the intersection of 12 and 160. The produce available wasn't extensive, but what was there was exceptionally fresh and everything we tried was delicious. We bought Meyer lemons for .50 cents each, some tangerines (unidentified type) which were very juicy and a nice blend of sweet and tart at the same time--cost may have been .99 per lb. but I'm not 100% sure, a freshly delivered baguette from a local baker, a small bottle of locally produced extra virgin olive oil (nice grassy flavor with the bread), and some fig vinegar that I haven't tried yet. They had local walnuts, apples, local honey and various squash as well but we didn't purchase them. A whole corner of the store was devoted to local wines, and it appeared they may offer tastings. I don't drink so that wasn't an area we explored.
The store is a non-profit intended to highlight the products of the area, and the woman who was working there was quite pleasant and kind. When I asked what type of tangerines were in the bin, she said that she didn't know but handed me a whole one and said "try it!". My impression is that what they stock will always reflect the season. I'd make it a point to stop there in the future, both to support a great project but more importantly, to pick up tasty fresh produce and gifts.
