The quality of the products you use will determine the quality of the end product.
There is also an overlooked rule in The Only Trip of a Lifetime. Which states that all the crap of this world is just not worth your while or back strain... So treat yourself to what you deserve and avoid the bottles of Smirnoff, Jose Cuervo, and Gordon's.
