you can buy assorted tequilas and here they claime that they have more than 500 brands of any kind of tequila you want (just don't buy jose cuervo ok). when you say tequila in mexico, they ask you what kind (like ordering a dimsum in china, they ask you what kind?) of tequila. There are two basic categories of tequila: mixtos and 100% agave. Mixtos use up to 49% of other sugars in the fermentation process, with agave taking up the remainder. Mixtos use both glucose and fructose sugars.
Tequila is usually bottled in one of five categories:
Blanco ("white") or plata ("silver") – white spirit, un-aged and bottled or stored immediately after distillation, or aged less than two months in stainless steel or neutral oak barrels;
Joven ("young") or oro ("gold") – is the result of blending Silver Tequila with Reposado and/or Añejo and/or extra Añejo Tequila;
Reposado ("rested") – aged a minimum of two months, but less than a year in oak barrels;
Añejo ("aged" or "vintage") – aged a minimum of one year, but less than 3 years in oak barrels;
Extra Añejo ("extra aged" or "ultra aged") – aged a minimum of three years in oak barrels.
What to buy: With 100% agave tequila, blanco or plata is harsher with the bold flavors of the distilled agave up front, while reposado and añejo are smoother, subtler, and more complex. As with other spirits that are aged in casks, tequila takes on the flavors of the wood, while the harshness of the alcohol mellows. The major flavor distinction with 100% agave tequila is the base ingredient, which is more vegetal than grain spirits (and often more complex). Fine Tequilas and the cheapest ones are 300 mexican pesos for a 750 ml bottle (hey this is not the cheap Jose Cuervo Kind ok but the premium kind and more expensive than patron) and depending on the brand goes up to 700 mexican pesos for a 1 liter bottle. the tequila stores are found everyhwere here in avenida de revolucion and throughout tijuana.
What to pay: again it can be as low as 300 mexican pesos a bottle to as high as 700 mexican pesos a bottle depending on the brand and depending on the kind of bottling if anejo or reposado, etc.
There are plenty of liquor stores in TJ, especially on La Revolucion. You can cant great deals on alcohol here. Customs will let you go through with 1 ltr of hard liquor per person.
What to buy: I like to stock up on my tequila here. A few of my favorites are Centenario, Casadores or Don Julio. Centenario, being the cheapest also goes down the smoothest. I also purchased Mezcal.
Another one of my favorite tequilas is Patron but that one is made in the US and therefore cheaper to buy it at home.
Legally, you may only bring ONE litre of alcohol back over the US border. Tequilla, Kaluha, rum... it's your choice.
What to pay: Compare shops. Most prices are about the same shop to shop but if you're a tightwad, you may be able to save a few bucks further up Revelucion Ave.
There are hundreds liquor stores in Tijuana which sell a lot of various liquors, wines, beer to U.S. citizens.
Remember: you can bring with you only 1 liter (33.81 oz) of alcohol, duty free.
What to buy: Mexican liquors (Tequila or Baja wines for example).
What to pay: Less than in the USA.
