So you are standing in the liquor store trying to decide what you want to buy. After way to long going back and forth you just buy a bottle. This could have been for various reasons, it had a cool design (we all done that), the "expert" recommend it, you just wanted to try it.
You buy the bottle that everyone tells you is cheap, not good, lacks depth,...etc but you just have to see for yourself.
When you finally get around to trying it you are like.... and you take another sip. Excitement washes over you because you found a new staple for your collection.
What bottle did that for you?
Now I guess the reverse should also be ask.
What bottle have you bought that was hyped up and you couldn't wait to try it? You make a nice dinner get your special glass out and take that first sip. Nothing. No wonderful sensation. You take another sip and complete disappointment washes over you and you ask yourself "How much did i just spend and why did I spend that?"
You now have another "Guest bottle".
