Miss the Official G&T to Woodfords Notice
 

A gentleman who reminds me of "The Most Interesting Man in the World" used to frequent the Delta forum. No greater love this man had than Woodford's straight up.

Anyway, he kindly informed us Delta flyers when it was time to switch from our summer G&T's to Woodford.

Personnally, in Delta first class, I drink tequila with ice + a slice of lime.
In their Skylounges, the Filandia Vodka and Meyers Rum are the only free brooze that does not suck, so I'm limited to drinks based on those.

Sparkling Mineral Water, 24/7 - 365.

As I fly Delta this is exactly what I do too. ^

G&Ts are a year round drink for me.

For sure. A Stinger is my go-to winter drink. I enjoy scotch, bourbon and whisky much more in the fall and winter. Hard for me to envision ordering a gin and tonic outside of the summer. Some things just go better with the season.

The seasons definitely bring on new drinks of choice for me: in the warmer months, it's Sauvignon Blanc, Rose, G&Ts, and light beers then as it gets colder Cabernet and scotch. And not to be one of 'those people', but the Merlot US Airways is currently serving is pretty bad, so Heinekens for me this winter!

A little, I like some hot drinks in the winter I'll generally not drink in the summer (Hot Toddies, Irish Coffee etc.) plus for not drink drinks I'll drink far more hot chocolate and tea in the winter and less beer than in the hotter months.
