  • Mechanics of late fruit addition in fermentation?

    Background: We like the sort of robust chewy red that clings to the glass and has real depth of flavour - being happy to pay the price of long maturation times that go with this. To achieve this I put rather too much elderberry/blackberry etc in the recipe and rely heavily on a fruit press for flavour extraction. i.e. I typically press the fruit adding both pulp and juice to the primary fermentation, and then again press the pulp when transferring to secondary. Bananas and red grape juice instead of water help as well and the result we like (a lot ).

    I have read a few passing references here which sugest delaying adding fruit addition to secondary or even post fermentation so as to improve flavour retention. But how (in the context of my desired wine style) would you go about this?

    a) Perhaps make the #1 style wine and add the fruit later? I don't really fancy this one as it would seem likely to produce a lighter and less concentrated wine than I am looking to produce but perhaps I am wrong. At the end of the day I would rather add elderberry & blackberry juice/pul/whatever to an elderberry/blackberry wine than to some other base wine.
    b) Do some sort of fake sugar & nutrient wine fermentation in primary and then add the pulp & juice afterwards? Doesn't seem like 'good winemaking' practice to me and even less acceptable to me than using a base wine.
    c) Press fruit and reserve juice. Add pulp and sugar to primary then add back in the juice on transfer to secondary or even at first racking. This appeals as a potential method as it should preserve the fruitiness from the juice while still providing a good must for the initial fermentation. On problem I see is that reserving the juice while still adding the sugar to primary will increase the diissolved sugar% and possibly cause problems with sticking fermentations. Of course I could reserve some of the sugar as well and add this in with the juice later, but then we are fermenting the juice again which is what we are trying to avoid in the first place.
    d) Add the juice & sugar to primary reserving the pulp. When fermentation has almost finished add the pulp for alcoholic extraction. This seems an ideal method - until considering that the delicate flavours and fruitiness you are trying to preserve are probably located more in the juice than the pulp.

    So, different ways but all seeming to have drawback. Maybe the answer is a mix of methods or reserving part only of juice or pulp or both but if so how much? Any views on what actually is the best method?

    The "base wine" using grape juice, or even sugar and water base wine having fermented to around 16% alc by volume with then the addition of the fruit at the latter stages (to dilute alc to around 12%), or even at the end of fermentation, will retain more of the fruitiness/original ingredient flavours than ANY other method.

    It didnt seem "right" to me when i first came across these methods, but i have had it proven to me, on more than one occasion that it actually works.

    this is an area that has been explored by winemaking greats such as Gladys blacklock (from the past) and Bill smith (from the here and now....award winning wines.....available on Amazon) a fellow judge and colleague

    some fairly radical ideas and methods, but the more i look into it, the more I learn that the "perceived" wisdom......isn't always as wise as one would like!

    regards

    p.s. watch this space for a tutorial on just this very subject (im an incredibly busy bunny though (grapefest on the horizon....ooo brackets within brackets!!!)....so it may take a little time)

      The short answer is of course..........


      late addition mechanics?

      the later you add, the less will be blown off by vigorous fermentation, therefore the more of the original fruitiness is retained, giving a more varietal correct wine. Basically because it is a much gentler extraction, using the alcohol to do the work, rather than the fermentation blowing off the flavour/colour compounds.

      hope this helps


      although I feel a virtual wine circle discussion looming large over it

        I know you said that you do not have time for the tutorial yet, but do you have a suggestion for blackberry and elderberry wine using this method. I'm thinking along the lines of a strong no1 maybe using red grape juice and then adding the fruits after fermentation, just need an idea for amounts and anything else i would need to do

        ta in advance

          OK

          just for starters...and totally off the top of my head.....



          take a wine No 1

          but....mkae the initial SG around 1.100...ferment to almost dry...then add 2lbs elderberries, and 2 lbs blackberries (at around 1.010)


          then ferment to dry



          run alongside this batch...a wine made from 2 lbs elderberries, and 2 lbs blackberries




          when all finished (racked andd botled) compare the two

              i think i'll give this (off the top of your head recipe) a try with my stock of frozen blackberries. if i get organised enough i'll do a comparison brew, but i'm guessing that the much enhanced fruity flavours will speak for themselves anyway.

              one question .... 2lbs of blackberries and 2lbs of elderberries will add about 1 and a bit litres of juice to the brew i guess?
              To most people solutions mean answers. To chemists solutions are things that are mixed up.
              A fine wine is a fine wine, 1st time may be by accident, 2nd time is by design - that's why you keep notes.

                well if you want to blow off all flavour compounds this is certainly the yeast to use.


                all you are doing there is making two different strength brews and blending....im talking about running side by side tests to see what method retains more varietal phenols. One traditionally brewed, and one that is brewed "slightly" higher and them fruit additrions added very late....taking the volume down to 12%

                details later....

                  Thanks bob, i will start this at the weekend and do a proper comparison

                  and it shall be known as "totally off the top of my head wine"

                    take a wine No 1
                    Or make a base wine from elderberries & blackberries ?

                    I would normally ferment the elderberries on the pulp for 6 days (a bit long I know) adding the blackberries at day 3 (giving the BB less time so as to avoid bitterness from the pips) and then strain to secondary. Adding the pulp later at end of fermentation will by intention changes the conditions i.e. less vigorous fermentation and the presence of alcohol for extraction, do we think the old contact times for pulp fermentations (6 & 3 days in my case) still hold good or do we need longer/shorter extraction times using these new methods?

                      to be a fair comparision i would have to use the same yeast for both wines, i have

                      lalvin EC-1118
                      lalvin K1-1116
                      Gervin GV3 yellow label
                      Gervin GV4(26) purple label

                      suggestion for which would be best

                          I think you may be missing the point here.....the idea is to add the fruit late so the phenols don't get blown off by the vigorous early fermentation, making a base wine from blackberries and elderberries defeats the object

                              I understood that tannins come out preferentialy in higher alcohol conditions, so with tanninic fruits like elderberries, you get the fruit out of the must early to keep down the tannin level. By adding fruit at the end of the fermentation, I can understand how you'd improve the fruit flavours, but you'd surely risk having a tannin kick...?
