Most things really. We have loads of spirits, because we rarely drink them (except for gin) so: scotch, brandy, rum (white and dark), vodka, Calvados, tequila, Pernod, grappa and Mezcal.
Vermouth (red and white) mostly used in cooking, Aperol (love an Aperol spritz), and fortified wines (Madeira, Marsala, sherry, several kinds of port) also mostly used for cooking (except for the port).
Stickies: Cointreau, Chambord, Kahlua, Poire William, Grand Marnier, Limoncello, Baileys, kirsch, Drambuie, Amaretto, .
Oh, and Pimms, plus wine (red, white and fizz) and beer. I believe there may be a rather old bottle of Rekorderlig lurking at the back of the fridge. And there's home made sloe gin out in the garage.
I realise this makes us sound like pissheads, but if we were pissheads, we'd have drunk it all!
For gin lovers, Tesco have quite a good offer on Tanquerays atm: £25 for a litre. I'm sure it was around £20 a bottle last time I bought a bottle, which was ages ago as the last 2 bottles were gifts.
