Have you found this at YOUR local farmers' market? I just found it today at ours in Middletown's North End. WHATTATREAT! 1/2 gallon in glass. It's delicious! I can't wait to make gelato with it, but meantime, I just had a glass and it is mm-mm-GREAT!
I know he goes to the Higganum farmers' market, too. I hope he finds a place to sell the milk in the winter. Locally, I recall Salem Valley Farms used to sell milk in glass at Portland's Tri-Town (and the now defunct PCM: Portland Country Market).
Anyway, a cool and delicious find. Try it if you see it! MOO.
