Wedding Alcohol Tiers — worth to splurge? Specific Alc listed

Hi yall!

My partner and I don’t drink, so we’re not super familiar on alcohol and their taste. However, we’re providing an open bar to our guests.

Right now, our package includes the Bottom Tier, however, I was wondering if it makes sense to splurge extra $2k for middle tier, or $3k for top tier?

Bottom Tier – Barton Vodka, Beefeater Gin, Calypso Rum, Dewars Scotch, Jim Beam Whiskey, Montezuma Tequila

Middle Tier – Tito’s Vodka, Beefeater Gin, Bacardi Rum, Dewars Scotch, Jack Daniels Whiskey, Jose Cuervo Tequila

Top Tier – Grey Goose Vodka, Tanqueray Gin, Bacardi Rum, Chivas Ragel Scotch, Jack Daniels Whiskey, Jose Cuervo Tequila
