Final answer:
The statement that highland agaves are larger than lowland agaves is true in regard to tequila production, highlighting the impact of growth regions on the characteristics of agave and the resulting tequila.
Step-by-step explanation:
When it comes to tequila production, the correct statement is that highland agaves are larger than lowland agaves. This is an interesting aspect of agave growth, as it highlights the differences between plants grown in different regions and how those differences impact tequila production. The central flower spike of the agave plant is not where most of the fermentable sugars are; instead, they are contained in the agave's core, known as the piña. It is important to note that blue agave is not particularly amenable to machine harvesting due to the plant's structure and the careful processing it requires. Highland agaves are indeed typically larger and often thought to produce a sweeter and fruitier tequila than their lowland counterparts.
