cheap shots i haven’t tried yet?

and by shots i mean liquors (is that the word?) that are like 35%+ i can have as a shot! the sheer amount of bottles in the alcohol section of tescos still overwhelms me but i’m tired of vodka, gin and tequila😭 i know i still have rum left tho but i can only really think of whiskys and brandy? anyone know what else is widely available that fits in the genre of drink i’m looking for if that makes sense😭 i had a heavy sambuca phase and now that makes me feel ill😭
