Welcome to series two of Scran - the podcast that's passionate about food and drink.

We are now airing fortnightly and this week, listeners are invited to take a stroll in some ancient woodlands in Perthshire as host Rosalind Erskine chats to founders of Birken Tree, Rob and Gabrielle, about how and why they harvest Birch water and the health benefits provided by it.

Rosalind also chats to restaurant critic for the Scotland on Sunday newspaper, Cat Thomson, about foraging finds, menus and what she's cooking now we are all at home.
