5.0 / 5.03 ReviewsAmazingI used it to make 5 gallons of home grown peach wine. I know...it's red wine yeast...but. After only 10 days, not 3 weeks the yeast was exhausted. I measured SG and did the calculation...alcohol 15.5% ! I highly recommend... worth the $.September 19, 2018Purchased
5 months agoI used Wyeasy 4946 to get a “stuck” mixture get movin again. Its working overtime and it looks like I’m getting 6 gallons of wine instead of compost fodder. Thank you MIDWEST!!!September 30, 2017Purchased
