So coming from someone who owned a charcuterie business. She needs an LLC, Food license, insurance – and more especially if in CA. atleast if she wants to be legal about it.
Also obviously whatever she is charging for these classes should be taxed so she can pay taxes for her LLC. also – if she is preparing anything it might need to be in a commercial kitchen.
Also technically to include the wine in the price package she needs a soft liquor license.
