Don't want create more confusion in your life but if you have other choices tomorrow I would pick something else instead of rc-212... Not really the best choice for a Merlot or Cab... But better then what you have now! Read that link I sent you and pick something that sounds like what you are trying to achieve... Just be careful not to pick something that needs a lot of nutrients unless you know how to do that...
I think this is what they have. Unless they have more they don't have listed in their catalog
Yeast D-47, 5 grams ...Price: $.75 / Recommended for making wines from white varieties such as Chardonnay and rosé wines. An excel- lent choice for producing mead, however be sure to supplement with yeast nutrients, especially usable nitrogen. An excellent choice for dry whites, blush wines and residual sugar wines.
Yeast EC-1118, 5 grams ...Price: $.75 / The EC-1118 strain is recommended for all types of wines, including sparkling, and late harvest wines and cider. It may also be used to restart stuck fermentations. An excellent choice for champagnes and late harvest wines. Also a very good choice for dry whites.
Yeast K1-V1116, 5 grams ...Price: $.75 / The K1V-1116 strain tends to express the freshness of white grape varieties such as Sauvi- gnon Blanc, Chenin Blanc and Seyval. The natural fresh fruit aromas are retained longer than with other standard yeast strains. Fruit wines and wines made from concentrates poor in nutrient balance benefit from the capacity of
K1V-1116 to adapt to difficult fermentation conditions. Restarts stuck fermentations. Highly recommended for dry whites, aged reds, and late harvest wines.
Yeast RC-212, 5 grams ...Price: $.75 / RC 212 is recommended for red varieties where full extraction is desired. Lighter red varieties also benefit from the improved extraction while color stability is maintained throughout fermentation and aging. Aromas of ripe berry and fruit are emphasized while respecting pepper and spicy notes. An excellent choice for both young & aged red wines.
Yeast 71B-1122, 5 grams ...Price: $.75 / The 71B is used primarily for young wines such as vin nouveau and has been found to be very suitable for ice wine, blush and residual sugar whites.
