Apfelstrudel/Strudel is a strudel, sweet pastry
Außenseiter literally, outsider. A foreigner
Bauernschlau this refers to a type of intelligence that might be unexpected from an "uneducated" folk. When someone refers to this "farmer's cleverness", it is usually in reference to a brilliant and unexpected idea, or prank, or joke. Kind of like "playing dumb" and getting the best out of something.

Sommerfrischler a slang term for vacationers, literally meaning someone who is out to take in the fresh summer air
Speck smoked side of pork, bacon (very special to the region and as unique as Canadian bacon is to Canada).
Stube in a home is like a parlour, but it's not. There is usually a tiled oven, table and chairs, and sometimes a single bed near the tiled oven or something else to lounge on. It was used as the multi-functional gathering room in every house.
Stube in a guesthouse was usually the dining area, also containing the main heating source of the house, the tiled oven.
Tracht traditional dress, man or woman but can sometimes refer to only the man's suit
Vorsäß literal meaning, "before the pasture". There are three stages when taking livestock up to the alpine pastures. Before the snow melts at the very top, farmers took their animals to the Vorsäß to lower pastures, then to the higher fields, then back down to the lower pastures before bringing them home to the valley for the winter.
