Nothing really spectacular. Gluwein is a tradition from my family (which has some roots in Germany). I always had it at my parents home during Christmas time. And since my wife enjoys it, she agrees with me making a batch for Christmas. Tacos came about because my wife makes good tacos and neither of us is much into the traditional ham or turkey dinners which are common. One year, we just agreed to tacos and that’s been that. Christmas now means tacos and Gluwein.
