Luxuriate in the orchard, listen to the birds and rejuvenate your skin and your mind. Beautiful iron clawfoot tubs in the dappled shade of old apple trees,  a wood fired sauna, mud mask, blueberry smoothies, herbal teas, a splendid way to spend the day unwinding and opening up to the pleasures of summer in Maine. If you've been waiting for an excuse to treat yourself, this is it.

Thalassotherapy involves the therapeutic use of seaweed in a bathing context. It is a common alternative therapy in European spas. Using marine elements is an excellent example of the mind-body connection and how important it is to balance that connection for long-lasting wellness. In addition they are offering skin wraps made with botanical extracts of vinegar and bentonite clay. Base price is $50 per person for the whole experience.

Food Preservation Workshop using Solar Drying with Smithereen Farm; August 25 - 25

Solar drying can be among the simplest, least energy intensive, lowest-tech method of food preservation, widely practiced around the world and throughout human history. Smithereen Farm has received a USDA grant to promote Washington County local foods; one of the focus areas has been on value-added processing. Whether it's herbs, mushrooms, salt fish, algae or fruit -– dried foods are a good way to preserve the harvest, extend the season and create products with good markets.

Smithereen Farm, in partnership with Greenhorns, will host a FREE digital workshop focused on solar drying. We have undertaken a literature review and consulted with experts in the state to bring forward what is known and relevant to small growers looking to bring sundrying into their operation. As part of the grant Smithereen Farm is making available a shared processing space, commercial kitchen, and drying greenhouses – these can allow other producers and wild harvesters to safely process their harvest.

The workshop will cover what approaches and technologies are available, the relevant rules, and other considerations. This session will be virtual on Zoom and has been moved to Friday August 25th at noon, and will be recorded. If you are interested in renting the shared-use facilities please be in touch with Alex at [email protected].
