I am from India and making homemade wines and mead for past 6-7 years. until recently I don't even have access to wine yeast. I use to mature baker's yeast in fruit juice for a week and then use to start to start a new culture from this yeast in fresh juice. After consecutively followiing the same process for 4-5 times. I generally had yeast strong enough to deal with high alcohol.Now wine yeast is available but, its overpriced because of import duties. For a packet of 5 5g small pack of redstar or lalvin wine yeast I end up paying close to $18-25. which leave little room for other additives. Besides I want to use as little chemical in my wine and mead as possible. I am looking for natural substitute of pectolase, tanin and yeast nutrient. Can somebody guide me in this.
