I didn't venture into these aisles much, but from what was drunk at parties in my flat, imported American beers were considered pretty special. Juices were another issue. They only came in one-liter containers, which aren't very large, although considering that regular Scottish beverages were about half the size of the average American beverage, it's understandable why the containers were so small. They had orange juice, apple juice, pineapple juice, and a couple others, but I don't think Scotland had caught onto the idea of cranberry juices or the more interesting fruit juice blends. And there were many more varieties of other meat products, such as bacon, which is not like our bacon but thicker and less crispy.
Meats come frozen or fresh.
Frozen is much more convenient for those who are studying abroad, as it can just be stuck in a freezer the entire semester. Frozen vegetables were also a big deal in Scotland. The next aisle was the dairy aisle. Almost a third of Tesco's refrigerator was devoted to various butters and margarines. There was clover margarine, sunflower margarine, safflower margarine, and many others.
