We've been using Amador Wine Shipping and its services for both our businesses as well as personal wine shipments. There is not a better place that will take care of wine shipping AND from various wineries which is almost impossible otherwise.
They have many options and will ship when you ask for it. They provide a nice cool storage area for wines and overall they provide us with a good quality in service from beginning to end.
Not sure why a post from 8 years ago still resonates on here, but that person only posted this one review, so hopefully others will read other reviews that are more current.
