The "Conservatory" cocktail. Named since this has a sort of herbal (even medicinal, in a good way), floral quality to it, that puts me in the frame of mind of sitting in a garden or conservatory as gentle sunlight filters through the leaves above - perhaps reading a pleasant book, perhaps simply enjoying the simple pleasures of the flowers and ivy.

Recipe:
1.75oz bourbon (I used OGD, the ordinary 40% bottle)
0.25oz demerara semi-rich syrup
0.75oz lemon juice
4 dashes Angostura aromatic bitters
4oz ginger beer (I've made it with Fever Tree and Q so far. I favor Fever Tree but both worked great. I'm sure Reeds would be terrific too.)
Lemon wheel for garnish

Build in chilled highball glass, stir gently before adding the ginger beer, then top with ginger beer and ice. Garnish with lemon wheel.
