This is a blend of white wools from flocks raised in South America. Yes, we know how vague that sounds! What we can safely say is that it is a very high quality wool. Dual-purpose, wool-bearing sheep are raised in two broadly defined regions of the continent: in the highland of the Andes mountains, and in the southern "cone", as the continent tapers southerly to a point moving away from the Equator.
The latter region contains two of the highest wool producing countries, Argentina and Uruguay. Merino sheep do especially well in Uruguay. Wools from this region are of the fine-to-medium range. In the Andean highlands of Peru, slightly coarser wool is the norm, but the sheep are mostly raised by smallhold farmers, rather than larger commercial concerns.
We don't have a micron width for this wool, but it feels somewhere in between a Merino and a Corriedale in terms of softness. The staple length looks to be between 8-12cm. Each bag contains 100g of wool.
