Alfalfa is a 7,000 hectare South African farm owned by the van der Merwe family, with 410 hectares dedicated to 19 grape varieties such as Chenin Blanc and Pinotage. The farm is located in the Breede River Valley near Worcester, and the winery, Alvi's Drift, takes its name from a low water bridge built by the family's ancestor. The farm and winery have been expanded over generations and now include a game reserve in addition to vineyards, orchards, and a dairy facility. Alvi van der Merwe and winemaker Linley Schultz currently manage the 6,000 tonne winery and produce wines under the Alvi's Drift
