In a large pitcher, mix together the pineapple juice, lime juice, and hot sauce. Give it a stir, then set aside.
Make the Micheladas
Start by rimming your glasses with Tajin:Pour the Tajin onto a small plate then rub a lime wedge around the rim of the glass then dip it into the Tajín. Pour 1 cup of ice into a beer mug, then pour in 1/2 cup of the Michelada mixture. Top off your mug with beer, then give your Michelada a stir. Garnish with a pineapple wedge, then serve.
Note*** if you're using a glass smaller than a beer mug, pour in about 1/4 cup of the Michelada mixture into the glass instead of 1/2 cup.
